Unit Learning Outcomes:

LO1 Use an appropriate design tool to design a relational database system for a substantial problem.
LO2 Develop a fully functional relational database system, based on an existing system design.
LO3 Test the system against user and system requirements.
LO4 Produce technical and user documentation
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 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:
1. 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.
2. You have decided to implement a query language into the relational database system. The developed
system will be demonstrated to your manager in the report including:
 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.

Database Design
Scenario of the chosen system: Student Grading System
System Requirement Specification (SRS): The client requirement asked their system had to operate
smooth and effective. They want to manage their student’s grading on system easily to avoid confusion and shortcomings in
their management period. The client objective is managing student like: one student can learn how many classes, subjects?
And when they input the student information into system then how the system working? From class id, subject that the
student learns until the grading or result of this student.

Logical design (ERD): The entity relation design without regard to what RDBMS or system it will be on. One
common method of depicting entities and relationships in a diagram.
Figure 1 Logical design by app.diagrams.net
Explanation: As we had mention that we develop the student grading system for university. In this ERD, we designed at
least 4 interrelated tables to shown client about basic ideas of us. We used 4 entities including: Lectures, Class, Grading,
Student, Subject. In Lecture’s table, it has lectureID, LectureName, Address. In Class’s entity, it has ClassID, ClassName,
lectureID, StudentID. In Grading’s entity, it has SubjectID, SubjectName, Subjectresult. We set primary key for each entities
table: lectureID for Lecture’s table, ClassID for Class’s table, GradingID for Grading’s table StudentID for Student’s table and
SubjectID for subject’s table. After set primary key, we combine each entities which set primary key to each corresponding
entities of another table which set foreign key. In our student grading system project, one lecture can teach many classes, 1
class can grade many subjects and 1 class can be learned by many students.

Physical design: The design adapted to the RDBMS and system constraints and features. After we design the logical
of user requirement, we implementing the physical design by SQL server.
