tables You want to include more than just the basics so you will implement a fully functional database system which will include system security and database maintenance features You have decided to implement a query language into the relational database system The developed system will be demonstrated to your manager Your manager has asked you to include in the report: Assessing whether meaningful data has been extracted through the use of query tools to produce appropriate management information Evaluating the effectiveness of the database solution in relation to user and system requirements, and suggest improvements Once the system has been developed, you will test the system and your manager will complete a witness statement indicating how your tests are performing against user and system requirements You will produce a brief report assessing the effectiveness of the testing, including an explanation of the choice of test data used Page Lastly you will produce technical and user documentation which will be given to the company You want to provide some graphical representations for ease of reference in the technical guide, so you have decided to produce a technical

discipline and practice in the management of people in an organization, has evolved and developed into different areas These disciplines and practices have gone through a process of trial and error, theory building and testing of various concepts by practicing managers and academics The underlying forces behind the evolution and development of human resource management have been (and still are) mainly environmental, and the quest for knowledge of better ways of acquiring and utilizing labor The changing organizational environment in the marketplace pushed managers to improve efficiency in the production and service delivery processes by increasing their ability to use the best practices of people management at the time That is, employee management techniques or methods that would improve production, reduce service delivery costs, and at the same time ensure sustained availability of competent staff in the organization This study is devoted to providing organizations with a human resource management system of the evolution and development of human resource management and the way it works and influences people management in contemporary organizations 1.2 System description Human resources management system (HRMS) was created to include the best practices for service human resources departments within the company and is the work of all employees department The target group of the system that serves the human resource procedures is special for the employees and managers This system is also classified according to staff branches and departments as it is classified according to the work of multiple systems; In addition to that it is organized in terms of personnel (promotions bonuses– trainings- Benefit) This system of work area makes it easy to enter movements daily work , also organizes holidays, whether in the day or hours , Emission a monthly report full and detailed and accurate for all staff movements within a specified period (work required -work actual ) The proposed system will allow improve perform the job functions of the employees department and faculty by provide system allows: - Tasks are dispensed paper charged for the time and effort - Keep electronic records of employee's information, benefits, education, adjustments, evaluations and requests instead of paper files that need extra space Page - Electronic working will be easy to completion tasks - Also there are data facilitates retrieval and interact with them - The system flexible to add, delete, edit for employee record and all information belong to human resources management 1.3 Problem definition 1.3.1 Goals The aim of this study is to build the human resources management system to increase the efficiency of the performance and the safety of the decisions taken and the advancement of the institution The researcher will study the human resource management system requirements used in any company in order to build a human resource management system efficiently 1.3.2 Objectives We will build a web-based human resource management system (HRMS) to increase the performance and organization of the entire range of human resources management services by developing these sections: - Rules section - Compute the net salary after adding salary, promotions percentage and loans - Detailed reports section - Direct email communication - Statistical data charts - Training section - Vacations section - Salary - Attendance 1.3.3 Critical success factors Increased performance of the entire range of human resources management services Provide a single point of contact for customers to take human resources management system (HRMS) procedures or to request any clarification Expand the coverage of the human resources management system (HRMS) to include the entire human resources services, including human resources management system (HRMS) planning, performance management and Internet recruitment systems The human resources management system (HRMS) will allow for trend analysis and reporting 1.3.4 Organization chart and responsibilities This table will present all activities that will be developed on the human ressystem, objective of every activity and the target audiences for each activity Page Table (1.1): Organization chart and responsibilities Question Objective Activity Target Audiences How to control on the access of the system? Making saved authentication to the system Developing Rules section HRMS give employee rules to access any par of the system How to Compute the net Salary for the employees? To compute the net salary for everyone on the system Computing net Salary after adding Salary, promotions percentage and loans HRMS compute net salary for all employees on the system How to get all Detailed information about any part of the system? To get detailed reports about any part of the system Developing Detailed Reports section HRMS will extract all data on the system How to make direct communicate with the employees? To communicate with all employees quickly How to realize the change of data on the system? To represent all data on thesystem Managing communication with whole system members Representing data on the system in graphs and statistics Employees who are members on human resource management system (HRMS) All data on the system stored on database 1.4 Feasibility study: Information has been collected by reference to sources, written references and information published in scientific, research and literary sites on the Internet 1.5 Human resources management general rules: The human resources management team suggests to the management team how to strategically manage people as business resources This includes managing recruiting and hiring employees, coordinating employee benefits and suggesting employee training and development strategies In this way, general rules related to human resources management system Human resources provide benefits to an organization in a fashion similar to the manner in which financial and physical resources provide benefits Page INSERT
