Introduction Modern technology has supplemented computerized management information systems with new recipes to achieve enhanced performance than before, encouraging them to use their own scientific discoveries of modern technology to improve and develop its activities by increasing the completion rate, transaction accuracy, provide customer service in line with the needs and preferences helped accountable contribute the decision-making process. It is improving the quality of decisions, increasing their value and productivity based on the information. Demographic variables International Journal of Humanities and Social Science Research 22 among users of computerized management information have great impact on the performance development. Gad El Rab believes that accompanying these developments, the expansion in the use of information that computer applications has made one of its components key in order to take advantage of its large abilities which is equal to the increasing size of the organization, where it managed the importance of information systems in the benefits generated by such flexibility and speed of delivery, reduce costs and the possibility of providing useful information Systems in the appropriate time, in addition to being used on the level of administrative processes and activities at different levels. The preservation and dissemination of information is through the various aspects of the organization [19]. Gaza Electricity Distribution Company is private and limited joint-stock company, is working on the distribution of electric power in the Gaza Strip, and looks forward to working continuously to improve and raise the efficiency of its performance by relying on computerized management information systems, which are the backbone of the administrative development, to make the results of performance in line with the company's goals. Computerized management information systems allowed great opportunity for various business organizations in strengthening their competitiveness and achieve their desired objectives, also contributed to the development and improvement of the performance development by these systems rely on modern and sophisticated technology which enables these organizations to draw policies and directions based on real information and enable them to take correct administrative decisions, in addition to that computerized management information systems lead to develop and improve the performance of employees because of their relationship with the professional development of functional employees, and in the completion of the tasks and functions assigned to employees quickly, efficiently and with high productivity. The expansion of the business, and the presence of large organizational structures, prompted management to build a database and a larger system of positive interaction and structured to achieve its objectives and general goals, where the pursuit of this research is to identify the weaknesses in the computerized management information system in Gaza Electricity Distribution Company, and therefore attempt to treat and then be able to develop and raise the efficiency of the performance of their employees. So, the researchers tried through this research to answer the following main question: What is Performance development and its relationship to demographic variables among users of computerized management information systems in Gaza Electricity Distribution Company? The objective of this study is to:  To identify the perceptions of employees in Gaza Electricity Distribution Company toward demographic variables among users of computerized management information systems.  To recognize the effect of demographic variables of computerized management information systems and the development of performance in Gaza Electricity Distribution Company in accordance with gender.  To identify consequence of demographic variables of computerized management information systems and the development of performance in Gaza Electricity Distribution Company in accordance with age.  To discover the relation of demographic variables of computerized management information systems and the development of performance in Gaza Electricity Distribution Company in accordance with educational qualification.  To find out upshot of demographic variables of computerized management information systems and the development of performance in Gaza Electricity Distribution Company in accordance with years of services  To provide recommendations and suggestions to help improve performance by enhancing the use of computerized management information systems in Gaza Electricity Distribution Company.

International Journal of Humanities and Social Science Research 23 2. Literature review 2.1 Computerized Management Information Systems Resources AL-Gharbaoui reached to a positive relationship between the computerized health information systems and the level of functionality for those working in health centers [9]. Zinedine and Ajrami reached that electronic programs contribute to raising the performance levels and productivity of the workers at the Deanship of Admission and Registration in Al-Azhar University in Gaza, and that the software used in the deanship contributed to the selection of a qualified elements in the field of information technology [30]. Abu Karim concluded that the devices are the main requirement of computerized management information systems working to improve management performance systems, followed by users who are using information systems, then performance improvement, and software, while the least impact on information systems: technician specialists and databases. The results clarified that the response by the employees in the systems is high, and responding to maintenance by employees in systems is high, the results showed that the devices used are flexible enough, that the devices currently in use is one of the best and latest technology available, the management and operation of the databases is featuring high capability on the addition and modification, the management and operation of databases is characterized by high capacity storage, and there is statistically significant differences between the management information systems and the improvement of administrative performance attributed to years of service [1]. Al-Araby showed a statistically significant differences relationship between the use of information technology and (performance size, quality of performance, efficiency, simplify the work). The study also showed no statistically significant differences relationship between the use of information technology and fast task, no statistically significant differences about the impact of the use of information technology on job performance attributable to the variables (gender, educational qualification). In contrast, there were statistically significant differences about the impact of the use of information technology on job performance attributable to the variables (age, seniority, functional category) [6]. AL-Saraireh showed that the functionality of the faculty level was high, the researchers recommended that the universities to strengthen the functionality of faculty members, to identify their needs and desires to achieve the possible ones to satisfy them, and provide an incentive system, promotive, physical gifts, and moral, as they have a positive impact in maintaining the level of job performance high [16]. Myeong and Choi reached a positive change to the impact of information technology on decision-making policies [26]. Al-Otaibi concluded that there is clarity in a sample study of the importance of the use of information technology in human resource management, senior management supports the transition to the use of information technology to the management of human resources, provide adequate infrastructure to help in the use of information technology in management human resources, there are no statistically significant differences between the perceptions of the respondents attributed to demographic variables (gender, educational qualification, experience, functional level) [13]. Dweik showed that the computerized information health system currently used in the Gaza European Hospital has good effect on medical and administrative fields of the business as well as the medical and administrative decisions, and that there are constraints limit the effectiveness of health information systems and most important of them: the weakness of funds required [18]. AlHalabi concluded that the computerized management information systems requirements (physical, software, human and organizational) enjoys a high from the viewpoint of respondents efficiently, as the study found that there is no statistically significant relationship on the impact of computerized management information systems on the decentralization of the Ministry Finance in Gaza Strip due to demographic variables (gender, age, experience, educational qualification career, the scientific level) [10]. AL-Tahrawi found that the existence of specialized human resources management departments by (67%), non-governmental organizations provide financial resources to the development of the capacity of its staff internally and externally, and it will help them in the development of educational and academic standing, as well as an existing performance appraisal system on the basis of the bonus system [17]. AL-Omari found the presence of impact that statistically significant with the requirements of the operation and management information systems (physical, software, human, organizational) on the performance of employees in the telecommunications company, and statistically significant differences between the perceptions of the respondents on the subject of the study are due demographic variables (scientific level, years of experience, the workplace, the functional level), and the presence of good level of material resources, human resources, software resources and organizational resources. [12]. Supattra and Boonmak concluded that the administrative information and information technology increase the organization's effectiveness and efficiency of their performance and improve the strategic work in systems, when one rely on management information technology and information systems, the greater the efficiency of the organization and increased effectiveness and the better the culture of workers in the organization about the efficiency of performance and effectiveness [28]. Al-bshabshah reached to the presence of significant impact to the quality of information systems on the raising level of functionality, the presence of a strong statistically significant differences between the information systems of various dimensions and functionality of a relationship, the presence of a strong significant impact of software supplies on functionality, and there are significant statistical differences between the perceptions of the respondents attributed to (age, educational qualification, functional level) [7]. 2.2 Computerized Management Information Systems Computerized management information systems are the use of computers in the assembly and operation of the storage and dissemination of information, and notes that computers including content of the hardware and software serves as the tools you use certified information systems at Computer [27], management information systems is a comprehensive system works to collect all the information necessary for all management functions with the aim of administrative support private managers by providing in time clear and accurate information to help them plan and organize their work and thus take appropriate decisions in order to provide the necessary information, as others added to the definition of International Journal of Humanities and Social Science Research 24 computerized information systems [11]. The importance of computerized management information systems is highlighted in the fact that its main task is to provide the necessary data and processed to produce useful management information, in a timely manner, accurate and appropriate quantity and commensurate with the needs of decision-makers [23]., the information as a storage of the organization, including addressed from the information that allows configures of a historical description of their conditions, discovery of easy errors that might occur, which means that information systems should bring confidence to surveillance to be effective coordination and communication between the various interests through exchange of information and documents associated with the various flows, and because of their role in helping in the decision-making process by finding a basis or foundation for the analysis of the initial warning signs that stand out both internally and externally [20]. As well as helping to improve performance by increasing the speed of completion and accuracy of transactions, provide customer service in line with their needs and desires also help by reporting provided to support the process which make decisions and thus improve the quality of decisions and increase their value and productivity based on the information provided and the associated productivity organization [7]. The importance of management information systems for organizations classified into three main roles: support pilot operations, support decision making by managers, and support the development and implementation of strategies to achieve competitive advantage, also the importance of management information systems lies in the support of the organization and supporting basic operations [24]. 2.3 Computerized Management Information Systems and the Development of Performance The development of performance in organizations is linked to the optimal use of financial and human resources available in the organization through the use of appropriate methods to achieve the objectives of the organization and therefore based on clear and objective goals doable to achieve the best level of performance [14], it is not limited to the use of this organization on a field without the other but are used in organizations at the senior management level are strategic and competitive dimension, used on the middle management level, where useful in processes of implementation and described the information here as a tactical dominated by the character of repetition, also used on the lower level of management so as to enhance the monitoring process of direct and supervise the conduct of repeated operations [31]. Therefore, the researchers believe that the computerized management information systems help in the development of performance where they help to speed decision-making on a sound basis provided real information, adequate and in timely manner, and provide information to the various administrative levels and help departments in operations planning, control, regulation, facilitate administrative communication between all administrative levels, and help the organization in strategic planning, opening of new markets, working to increase the efficiency of the performance of staff development the development of management techniques, make the best investment of the available data, the speed of completion of transactions and accuracy, reduce cost, and improve the level of service, as well as take advantage of the electronic devices in the analysis, display and save information. Performance development and its relationship to demographic variables among users of computerized management information systems in Gaza Electricity Distribution Company lead to the following main hypothesis in this study: H1: There is statistically significant relationship between demographic variables among users of computerized management information systems and the development of performance in Gaza Electricity Distribution Company. H2: There is statistically significant differences between the perceptions of respondents about demographic variables among users of computerized management information systems related to the development of performance in Gaza Electricity Distribution Company, enhance personal variables (gender, age, educational qualification, years of service). 3. Research design 3.1 Study Population and Sampling This study conducted at Gaza Electricity Distribution Company. It is highly reputable one and established in 1991. The population is (1022) employees, the control sample (733). The usable sample was (520), which makes response rate (71%). The sample of the study was selected using random sampling from different management levels where all levels are affected by demographic variables among users of computerized management information systems, the study sample size was (360) questionnaires, (360) questionnaires were distributed on study participants, (306) were returned back with a percentage of (85%). Table 3 shows the properties and characteristics of the study sample. Table 1. Distribution of members of the study population according to the personal data (n = 306) Characteristics and personality traits The number Percentage% Gender Male 222 2..2% Female 22 2..2% Age Less than 25 years 9 2.9% From 25 years to less than 35 years 22 2282% From 35 years to less than 45 years 929 2282% From 45 years and over .6 99..% Educational qualification High school or less 96 ...% Intermediate Diploma 6. 92..% BA 992 .2.2% Graduate Studies 22 96.2% Years of service Less than 3 years 2. 2.6% From 3 years to less than 6 years .2 99% International Journal of Humanities and Social Science Research 25 From 6 years to less than 10 years 29 9.6% From 10 years and over 226 22% Table 1 shows that most of the study sample aged (35-45 years), and that most of the study sample of graduates, where the proportion who hold a diploma or higher education has reached (96.7%), the rate is normal in the company that provide electricity distribution services and other advanced services which require workers with educational qualification, and that the majority of the company's employees are highly experienced workers with 6 years and over of experience reaching (29.6%) . 3.2 Research Instrument The first dimension referring to the model used in the study is demographic variables among users of computerized management information systems and the second dimension of the instrument is the development of performance. The authors with the help of other research literature [2, 8-10, 14-15, 25, 29-39] prepared the questionnaire. A five-point Lekert scale of agreement was used for measurement, running from "Strongly Agree" to "Strongly Disagree", with a Neutral category for scale midpoint. 3.3 Search Tools The researchers prepared a questionnaire for the "Performance development and its relationship to demographic variables among users of computerized management information systems in Gaza Electricity Distribution Company." 3.4 Structural Validity The degree to which is a test measures what it claims, or purports, to be measuring. It shows the relevance of each field of study to the overall degree of the questionnaire paragraphs. Table 1 shows that all correlation coefficients in all fields of the questionnaire are statistically significant at the level of significance (a ≤ 0.05) and therefore the questionnaire fields are considered to be valid to what it was supposed to measure. 3.5 Validity and Reliability Assessment The study adopted Cronbach's α to measure the internal consistence reliability of the questionnaire. The results showed that Cronbach's α value for all dimensions were > (0.05). It indicated that the design of the questionnaire had a high internal consistency. The researchers used Alpha Cronbach method to measure the stability of the questionnaire, and the results were as shown in Table 2. Table 2: Alpha Cronbach test results to measure the stability of the questionnaire No. The field Cronbach's alpha coefficient 1. Physical resources for computerized management information systems 6.2.. 2. Software resources for computerized management information systems 6.296 3. Human resources for computerized management information systems 6.26. 4. Organizational resources for computerized management information systems 6.292 5. The performance of employees 6.92. 6. All fields of the questionnaire 6.962 Table 2 showed that the value of Cronbach's alpha coefficient was high for each field of the questionnaire ranging from 0.803 to 0.926. As well as the value of the alpha coefficient for all the paragraphs of the questionnaire was (0.958). This means that the reliability coefficient is high, so that the researchers were certain about the reliability and validity of the questionnaire, which made them confident about suitability of questionnaire for analyzing the results and answering questions of the study and testing of the hypotheses. 3.6 Statistical Procedures The researchers used the questionnaire data for analysis through statistical analysis software (SPSS). Nonparametric statistical tests were used because Lekert scale is a main statistical measure which used the following tools: Percentages, frequencies, and relative arithmetic average are mainly used for the purpose of knowing repeated variable categories, and benefit researchers in the description of the study sample. 1. Cronbach's Alpha Test was used to determine the stability of the paragraphs of the questionnaire. 2. Spearman Correlation Coefficient to measure the degree of correlation. This test is used to study the relationship between the variables in the case of nonparametric data. 3. Sign Test to see whether the average degree of responsiveness has reached a degree of neutrality, a 3 or not. 4. Mann-Whitney Test to see whether there were statistically significant differences between two fields of ordinal data. 5. Kroskal-Wallis Test to see whether there were statistically significant differences between the three fields or more of the ordinal data. 6. Multi-linear regression model. 4. Data analysis and discussion of results H1: There is statistically significant relationship between demographic variables among users of computerized management information systems and the development of performance in Gaza Electricity Distribution Company. H2: There is statistically significant differences between the perceptions of respondents about demographic variables among users of computerized management information systems related to the development of performance in Gaza Electricity Distribution Company, enhance personal variables (gender, age, educational qualification, years of service). The use of "ManWhitney test", which is suitable for comparing averages of two sets of data, to see if there is a statistically significant difference. "KroskalWallace" test International Journal of Humanities and Social Science Research 26 was used also to see if there is a significant statistical differences and this test used for comparing the averages of 3 or more data sets. There exist statistically significant differences that showed the perceptions of the respondents about the development of performance and its relationship to some demographic variables among users of computerized management information systems in Gaza Electricity Distribution Company due to the variable of gender. The following table shows that by using the "ManWhitney" test shows that the probability value (Sig.) for all fields of study were greater than the significance level (a ≤ 0.05) and then there is no statistically significant differences between the perceptions of respondents about performance development and its relationship to some demographic variables among users of computerized management information systems in Gaza Electricity Distribution Company due to the variable gender. This result explains that both genders do the same business and rely on the same computerized management information systems requirements, therefore, the impact of these systems on the performance of both genders is the same. 4.1 The results of the second main hypothesis Gende: Table 3: The relationship of demographic variables among users of computerized management information systems to performance development in Gaza Electricity Distribution Company, due to the variable (Gender). The field Test value Potential value Physical resources for computerized management information systems 6.929 6..22 Software resources for computerized management information systems -6.226 6...6 Human resources for computerized management information systems 6.266 6..9.

The following table illustrates that using KroskalWallace shows that the probability value (Sig.) is greater than the significance level (a≤ 0.05) for all fields and then there are no statistically significant differences between the perceptions of respondents about these fields due to the variable age. This can be explained in that the provision of financial support, information and training to be by job rank as well. As for the development of performance, those with small business employees are characterized by the novelty of science and speed of learning while aged employees have significant expertise advantage, thus, there will be no difference in the effect of management information systems and the development of performance due to age. This is consistent with the study of Al-Otaibi, which concluded that there were no statistically significant differences between the perceptions of the respondents attributed to demographic variables (gender, educational qualification, experience, job rank) [13]. The current study disagree with study results of Al-Araby, which showed that there were statistically significant differences about the impact of the use of information technology on job performance attributable to the variables (age, fiscal seniority, job category) [6], as well as also disagreed with the study of AL-Omari, which reached to the presence of statistically significant differences between the perceptions of the respondents on the subject of the study due to demographic variables (scientific level, years of experience, the workplace, the job rank) [12], as well as also disagreed with the study of Al-bshabshah which concluded that there are significant differences between the perceptions of the respondents differences attributable (age, educational qualification, job rank) [7]. 4.2 The results of the second main hypothesis Age: Table 4: Relationship of demographic variables among users of computerized management information systems to develop performance in Gaza Electricity Distribution Company, due to the variable (age). The field Test value Degrees of freedom Potential value Physical resources for computerized management information systems 9.2.9 . 6.622 Software resources for computerized management information systems -6.622 . 6.662 Human Resources for computerized management information systems 6.62. . 6.9..

The Development of Performance 6.692 . 6..62 There exist statistical differences among respondents attributable to the scientific qualification. The following table shows that by using Kroskal Wallace shows that the probability value (Sig.) for each of the fields," the material resources for computerized management information systems", "programming resources for computerized management information systems", "organizational resources for computerized management information system" and "all the fields of systems resources for computerized management information" was less than the significance level (a ≤ 0.05) and then there exist a statistically significant differences between the perceptions of respondents about these fields due to the educational qualification. This is a natural result, where the employees who do not have International Journal of Humanities and Social Science Research 27 scientific degrees and needs physical and software requirements deal less than experienced staff with scientific qualification who need higher physical and software requirements, and thus need greater financial support from the senior management as well as their needs for more accurate information and more recent software and hardware. As for the fields of "human computerized management information systems resources " and "performance development" shows that the probability value (Sig.) was greater than the significance level (a ≤ 0.05) and then there are no statistically significant differences between the perceptions of respondents about these fields attributed to the educational qualification. This because the information system is maintained and followed-up remotely and this does not require a scientific level by the staff, as well as for the development of performance as the company's employees have the level of their job and their performance and their dealings with the computerized management information system, each according to educational qualification, thus there is no relationship for the scientific level on the perceptions of the respondents on performance development. 4.3 The results of the second main hypothesis Educational qualification: Table 5: The relationship of demographic variables among users of computerized management information systems to develop performance in Gaza Electricity Distribution Company, due to the variable (educational qualification).

For each of the fields: "the material resources for computerized management information systems", "software resources for computerized management information systems", "human resources requirement" and "all fields of computerized management information systems' resources", the study shows that the probability value (Sig.) was greater than the level significance (a ≤ 0.05), then there is no statistically significant differences between the perceptions of respondents about those fields due to the variable of years of service. This is a natural result that the years of service have a significant impact on the development of performance, and employees with long-experience have greater relationships with senior management and with all other organizational levels. This is consistent with the study of Zinedine and Ajrami, which concluded that there is no statistically significant differences at the significance level between the job performance of employees and using electronic programs due to the variable (years of services) [30], also agrees with the study Al-Otaibi, which concluded that there were no statistically significant differences between the perceptions of the respondents attributed to the variable (experience) [13], also agrees with the study of Al-Halabi, which concluded that there is no statistically significant relationship on the impact of computerized management information systems on decentralization in the Finance Ministry in the Gaza Strip due to variable (experience) [10]. And disagreed with the findings of a study Abu Karim, which reached to statistically significant differences between the management information systems with improve management performance due to the variable of years of service [1]. and also disagreed with the study Al-Araby, which showed that there were statistically significant differences about impact of the use of information technology on job performance attributable to the variables (age, fiscal seniority, job category) [6], and also vary with the study AL-Omari, which reached to statistically significant differences between the perceptions of the respondents on the subject of the study due to the variable (years of experience) [12].

It was found that the three dimensions listed by their effect on development of performance: human resources for computerized management information systems, organizational resources for computerized management information systems, and Physical resources for computerized management information systems. But software resource for computerized management information systems has been excluded from the form because it is ineffective on the development of performance according to Stepwise, and can be explained by the existence of many variables which have greater influence resource for computerized management information systems and the development of performance. The coefficient of determination is equal to (29%). This means that 29% of the variation in the development of performance can be explained by the previous regression multiple linear equation and this ratio is considered acceptable in human studies. The remaining (71%) perhaps go back to other variables that may affect independent of the organization in the development of performance. Notes from the former table: probability value of each of the three dimensions is: (0.00), (0.008), (0.008), respectively, which is less than the significance level (a ≤ 0.05) and so there is substantial relationship for each of the three dimensions and the Development of Performance. 5.
