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 1 (Assignment 1)
Before you start the development process, your manager has asked you to produce a report for the CEO
of FPT, containing:
1. Clear statements of user and system requirements. The system must have at least 2 user roles, including
business processes and statistical reports for FPT university managers.
2. The design of the relational database system using appropriate design tools and techniques. It should
contain at least four interrelated tables.
You would prefer to produce a more detailed document, so you will produce a comprehensive design for a
fully functional system which will include interface and output designs, data validations and cover data
normalization.
Your manager would like on the report your assessment of the effectiveness of the design in relation to user
and system requirements.
Part 2 (Assignment 2)
Once the designs have been accepted by your manager you have been asked to:

 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.
3. 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.
Besides, you will produce a brief report assessing the effectiveness of the testing, including an explanation
of the choice of test data used.
4. 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 andtesting
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 thebest practices of
people management at the time. That is, employee management techniques ormethods that would
improve production, reduce service delivery costs, and at the same time ensure sustained availability of
competent staff in the organization.

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.

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

The human resource department must maintain information on each of the organization’s
employees for a variety of decision and reporting purposes. One part of this employee information
system is a set of human resource profile records.
An employee profile usually contains personal and organization-related information, such as name,
address, sex, minority status, marital status, citizenship, years of service or seniority data,
education and training, previous experience, employment history within the organization, salary
rate, salary or wage grade, and retirement and health plan choices.
The employee inventory may also contain data about employee preferences for geographical
locations and work shifts.
Another part of an employee is an employee skills inventory which contains information about
every employee, such as work experience, work preferences, test scores, interests, and special
skills or proficiencies
1.6.2.2. Position control systems
A job is usually defined as a group of identical positions. Every position consists of tasks
performed by one worker. The purpose of the position control system is to identify each position
in the organization, the job title within which the position is classified, and the employee currently
assigned to the position.
Reference to the position control system allows a human resource manager to identify the details
about unfilled positions.
1.6.2.3. Applicant selection and placement information systems
After jobs and the employee requirements for those jobs have been identified and after a suitable
pool of job candidates has been recruited, the candidates must be screened, evaluated, selected,
and placed in the positions that are open.
The primary purpose of the applicant selection and placement information system is to assist
human resource staff in these tasks.
1.6.2.4. Performance management information systems
Performance management information systems include performance appraisal data and
productivity information data. Performance management information systems data is frequently
used as evidence in employee grievance matters.
Careful documentation of employee performance was measured and reported is critical to
