INTRODUCTION

First of all, | would like to thank my mentor Nguyen Hoang Anh Vu for his constant support

in my studies and research, for his patience, motivation, enthusiasm and rich knowledge Without your wonderful help, | would not have been able to achieve this

In addition to my mentor, | would like to thank my friends who have helped me improve my knowledge of my subject And besides, | would like to thank the school for creating all conditions for me to have adequate facilities to help me complete my work

Last but not least, | would like to thank my family: my parents Phan Dinh Quy and Lam Thi Tam They are always be-hind to care and help me have more motivation to complete the work well! Network plays a very important role in life

From there, we will test the results that we have done Finally, we will operate the system and maintain it It is also a process to build a complete Database Design & Development system Let's find out in this assignment!

1.Use an appropriate design tool to design a relational database system for a substantial problem (LO1)

1.1 Design a relational database system using appropriate design tools and techniques, containing at least four interrelated tables, with clear statements of user and system requirements (P1)

1.2 Produce a comprehensive design for a fully functional system which includes interface and output designs, data validations and data normalisation (M1)

1.3 Assess the effectiveness of the design in relation to user and system

CHAPTER 1: DESIGN DATABASE

1 Use an appropriate design tool to design a relational database system for a substantial problem (LO1)

1.1 Design a relational database system using appropriate design tools and techniques, containing

at least four interrelated tables, with clear statements of user and system requirements (P1) 1.1.1 Scenario of the chosen system

- It chose to build various academic systems that would make the institution simpler to administer, such as: the online library, the student graduation system, the attendance system, the CMS system

- You are responsible for selecting one of the systems for developing the FPT university database Your responsibilities are:

=" Work with FPT to learn about existing system needs

=" Analysis needs and make unambiguous user and system requirements statements

" Conceive a relational database system utilizing design tools and processes

" Develop a completely working relation database system based on the system design that exists

" Test the system against needs of users and systems

= Produce user and technical documents

- Currently, FPT University has many discrete and inconsistent management systems such as: Online Library system, Student Grading System, Attendance System, CMS System, Scheduling System, Enrolment Systems, and so on

- Thus, it is time for us to create a unified system to effectively capture and manage students

in teaching and school management

- Therefore, we have proposed to build a “Student Management System” - a large system with a large source of data so that FPT University can thoroughly solve these difficult problems 1.1.2 System Requirement Specification (SRS)

- The creation of the FPT relationship database and division into clear and accurate tabulations can solve all of the difficulties listed above:

+ Major: Each Major has a major identity,

the main name and the foundation year et a E

+ Courses: every course has a course Reducing the amount

+ Student: Every student has a student

identity andbelongs to a certain class identity

(identified by ClassID) i

+ Program: Each program has a managing

Ai communication

code and aname for the program s See ea

online fee payment

subject : Each subject has a management code

and belongs to a certain discipline (identified by

MajorID) Figure 1.1-2: Student Management System + Subject: Each subject has a management code and belongs to a certain discipline (identified by MajorID)

+Result: Each result of the exam records a student who took the test for a specific topic during a certain test period (The student can take more than once a specific topic)

+ Lecturer: Each line in this table indicates a subject taught in a particular discipline within a certain program In this program, that subject is specified with a specific number of theoretical and practical periods and equivalent to how many credits (The number of credits includes both theoretical and practical credits)

+ Class: A class that has a class code to manage, belongs to a certain industry and is open to

a certain course, in a certain program The ordinal numbers are numbered in ascending order for classes of the same course, major, and program

- Functional requirements:

m1 " 7 ‘BT EC

The system has the main functions: storing information about students, subjects, study programs, classes, lectures, Along with that is the data retrieval at the request of users

This system has high security to avoid data loss,

Correct transaction actions are stored, and the system records the modifications and cancellations

Nice and easy to use external interface

The system stores data history for users to easily check and review

- Non-functional requirements:

There are no problems and the system operates stably 24/7 and high performance For instance, re-response time is within 1-2 seconds as well as throughput The system also have a scalability

It also contains many data and is quite reliable

Stable resilience and maintenance and excellent interoperability

- System requirements:

The system runs on Windows 7, Windows 8, Windows 10, Windows 11 (Preferred Windows 10)

Processor: Processor clocked at 1 gigahertz (GHz) or higher, or SoC

RAM: 1 gigabyte (GB) for 32 bits or 2 GB for 64 bit

Hard disk space: 16 GB for 32-bit OS or 20 GB for 64-bit OS

1.1.4 Explanation

“+ For the system, Reasons ERD is suitable because:

- The relations of entities recorded in the database is shown in an Entity Relationship Diagram (ERD) An entity is an object, a data component in this context A collection of related entities is a set of entities They may have characteristics that identify their characteristics

- The ER diagram shows the logical structure of databases by defining the entities, their characteristics and displaying their relations

- Because the system requires a relationship database to be designed The tables are tightly connected according to the ERD graph The system may simply and conveniently provide statistics

on student data, topics Easily and scientifically import and export data, thus ERD is a good choice

“+ Explain about ERD:

- Firstly, we need to identify the primary and secondary keys of each table while designing

an ERD diagram:

" Asmooth underline is the primary key

" Foreign keys are not seamless, specified with underscores

+ Conversion of the logical design in table definitions: pre-deployment designs, table definitions, standardization, primary and external key relations, fundamental indexing

+ Physical data database design after deployment, frequently carried out by a manager of a database

Table 1.2-8: Class Data 1.2.3 Normalization:

- The process of arranging data in a database is normalization This comprises the creation

of tables and the establishment of links between tables according to rules to both secure the data and flexible the database by removing repetition and inconsistency

“+ There are many different normal forms:

- First normal form (1NF):

=" Remove repetitive categories from tables

=" For every group of related data, create a distinct table

= Identify with a primary key each collection of associated data

"Do not save comparable data by using several fields in a single table

- Second normal form (2NF):

" Create distinct tables for sets of numerous record values

=" Connect these tables to an alien key

" Records should not depend on anything but the main key of a table (a compound key, if necessary)
