Assignment Brief and Guidance:
You are employed as a Database Developer for a large IT consultancy company. The company has been
approached by FPT university which is expanding due to the growth of the number of students. FPT is
currently facing difficulties in dealing with managing the university. It decided to develop several academic
systems to manage the university easier including: Online Library system, Student Grading System,
Attendance System, CMS System, Scheduling System, Enrolment Systems, and so on.
You are tasked to select one of those systems to develop database for FPT university. Your tasks are to:
Work with FPT to find out about current requirements for each system
Analyze the requirements and produce clear statements of user and system requirements.
Design a relational database system using appropriate design tools and techniques
Develop a fully functional relational database system, based on an existing system design.
Test the system against user and system requirements.
Produce technical and user documentation
Part 2 (Assignment 2)
Once the designs have been accepted by your manager you have been asked to:
- Develop the database system using evidence of user interface, output and data validations and
querying across multiple 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.
- 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 and user documentation for a fully functional system, including
diagrams showing movement of data through the system, and flowcharts describing how the system
works.

1. Introduction. 1.1. Overview For more than a century now, human resource management, as a 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.

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.
1. Human resources provide benefits to an organization in a fashion similar to the manner in which financial and physical resources provide benefits.
2. The benefits associated with both conventional assets and human resources have value to the organization because these benefits contribute in some way to the accomplishment of the organizational goals. 3. The acquisition of human resources typically involves an economic cost and the benefits associated with such resources can personally be expected to contribute to the economic effectiveness. It follows, therefore, that these benefits are essentially economic in nature and are subject to measurement in financial terms. 4. Since the usual accounting definition of an asset involves the right to receive economic benefits in the future, human assets are appropriately classified as accounting assets. 5. It is theoretically possible to identify and measure human resource cost and benefits within an organization. 6. Information with respect to human resource costs and benefits should be useful in the process of planning, controlling, evaluating and predicting organizational performance.
1.6. literature review:
1.6.1. Introduction
Human resources are those who make up the workforce of some particular organization, economy or business sector. The "human capital" term may be understood as a synonym to the "human resources’" one. But at the same time, “human capital” one usually refers to a narrower view such as the knowledge the individuals embody as well as the economic growth. Some other terms that sometimes may be used instead of the “human resources” one include "talent", "manpower", "labor", "people" or "personnel". Any human-resources department of some organization is expected to perform human resource management, overseeing different aspects of employment (e.g., compliance with labor law and some of the employment standards), some aspects of dismissal and recruitment, as well as an administration of the employees’ benefits. Any human resources manager is known to be in charge for determining the work-related needs of the staff, using temporary staff or hiring employees in order to fill such needs, recruiting and training the best employees, supervise their work, managing employees’ relations, payrolls, benefits and compensations, preparing employees’ personal policies and records, ensuring high performance, ensuring equal opportunities for all the employees, dealing with discrimination and other performance issues. Ensuring that human resources practices conform to the regulations and pushing the employees' motivation so they achieve more within their organization, human resources managers might find the concept draw pro software a useful tool for making the needed human resources related drawings. The human resources flowcharts solution can be used while creating the human resources related drawings in the concept draw pro diagramming and drawing software, providing with a comprehensive collection of human resources themed icons, connectors, and images from the available stencil libraries, helping illustrating flowcharts, info graphics and workflow diagrams. Using this solution for mapping the human resources related management processes on every phase of human resource management, including the hiring process, the process of recruitment, payroll systems and human
This kind of systems can lead to a number of decisions beyond merely supporting the operational decision to retain, promote, transfer, or terminate a single employee. 1.6.2.5. FPT University reporting and compliance information systems FPT University reporting and compliance information systems provide information needed both to maintain compliance with government regulations and to improve productivity and reduce costs associated with employees
