• Provides database tables and the relationship between them

• Description designing a database (DB), a collection of data related to storage on

a computer through database management system as a basis for data query relatedsoftware

• Provide the entire needed database for OSM web application

1.2 Document Objectives

The Database Design Document has the following objectives

• To describe the design of a database, that is, a collection of related data stored in one or more computerized files that can be accessed by users or developers via a DBMS

• To serve as a basis for implementing the database and related software units It provides the acquirer visibility into the design and provides information necessary for software development

1.3 Intended Audience

• This document is intended for the following audiences

• Technical developers, who must evaluate the quality of this document

1.4 Scope

• This Database Design Document provides the basic database design of OSM web application

Trang 9

o Table, column definitions

o Column and row level validation rules (check constraints)

o Interfaces and dependencies with other components

• This Database Design Document of Online Service Market web application is composed of definitions for database objects derived by mapping entities to tables, attributes to columns, unique identifiers to unique keys and relationship

to foreign keys

3 Database-Wide Design Decisions

3.1 Key Factors Influencing Design

- The database should be designed independent when the frontend and backend are still being developed

- The database should be designed to meet the data warehouse principles 3.2 Performance And Availability Decisions

We use common dimensional tables for all the fact tables for better performance
