LIST OF THE ACRONYM

First of all, I would like to thank my mentor Vo Duc Hoang for his constant support in mystudies and research, for his patience, motivation, enthusiasm and rich knowledge Without yourwonderful help, I would not have been able to achieve this.

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

Last but not least, I would like to thank my family: my parents Pham Phu Loc and Phan ThiThu They are always behind to care and help me have more motivation to complete the work well!The network plays a very important role in life.

From there, we will test the results that we have done Finally, we will operate the systemand 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 substantialproblem (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)

CHAPTER 1: DESIGN DATABASE

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

1.1Design 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

Figure 1.1-1: FPT school

- For a big IT consulting firm, you are a Database Developer The FPT University hasapproached the firm and is expanding due to the increase in the number of students FPT hasdifficulty interacting with university management at the moment.

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

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

Work with FPT to learn about existing system needs

Analysis needs and makes unambiguous user and system requirements statements.Conceive a relational database system utilizing design tools and processesDevelop a completely working relation database system based on the system design

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

- Thus, it is time for us to create a unified system to effectively capture and managestudents 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 cansolve all of the difficulties listed above:

+ Major: Each Major has a major identity,

the main name, and the foundation year.

+ Courses: every course has a course

management code, the year beginning, and theyear ending.

+ Student: Every student has a student

identity and belongs to a certain class identity(identified by ClassID).

+ Program: Each program has a managing

code and a name for the program.

subject: Each subject has a management code and belongs to a certain discipline (identified by

major) 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 andpractical periods and equivalent to how many credits (The number of credits includes boththeoretical 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 forclasses of the same course, major, and program.

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.

Figure 1.1-3: Entity Relationship Diagram

For the system, Reasons ERD is suitable because:

- The relations of entities recorded in the database is shown in an Entity RelationshipDiagram (ERD) An entity is an object, a data component in this context A collection of relatedentities 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, theircharacteristics and displaying their relations.

- Because the system requires a relational 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, and topics Easily and scientifically import and export data, thus ERD is a good choice.

- Next, we need to define 1-n, 1-1, n-n relationships to be able to connect the tablestogether:

In a class that will have many different courses and different majors, this is a 1-n relationship.

Each major will have many subjects such as Program, network, web, and database, this is a 1-n relationship.

Each student will have many learning outcomes from many different subjects, thisis a 1-n relationship.

Each lecturer can only teach one subject and a certain course, this is a 1-to-1relationship.

Each major will have a specific program of study for that discipline, this is a 1-to-1relationship.

Each course will have many different subjects for each course and each subject, thisis an n-n relationship.

1.1.5 Physical design

- The materialization of a database in an actual system is a physics-based concept Althoughlogical design may be done regardless of the ultimate data base platform, many physical databasefeatures are reliant on the details and semanticity of the DBMS target.

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

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

CRITICAL EVALUATION

After completing this assignment with my own efforts and with the help of my mentor.During the learning process, he was very dedicated to teaching and always answered my questions.With the knowledge that I have learned, I have presented very fully the questions that Assignmentraised in brief, with clear and specific images Moreover, I am confident that I can self-study and can make the Database Design & Development process for business.

In addition, I have mastered the basics of Database Design & Development, so I candefinitely create a large Database Design & Development to help many people connect with each

After completing this report, I have understood and grasped the principles, analysis and specification of a Database Design & Development system and their operation Moreover, with Microsoft SQL Management System software, I can use it to design, and code a complete database to be able to develop a website or application.

I am now confident that I can select the necessary devices and build the development anddatabase management workflows that are right for me.

Database Design & Development is really great! Thanks to it, I understand how the devices
