This article mainly introduces the database design process does not include which processes, the article introduces in great detail, has a certain reference value, interested friends must read it!

The database design process does not include algorithm design.

The process of database design mainly includes requirement analysis, conceptual structure design, logical structure analysis, database physical design, database implementation, database operation and maintenance.

Database design

Database design (Database Design) refers to the construction of an optimal database schema and the establishment of a database and its application system for a given application environment, so that it can effectively store data and meet the application needs of various users (information requirements and processing requirements). In the field of database, all kinds of systems that use database are often referred to as database application system.

Define

(Database Design) refers to the process of designing the structure of the database and establishing the database on a specific database management system according to the needs of users. Database system needs the support of operating system.

Database design is the technology of establishing database and its application system, and it is the core technology in the development and construction of information system. Because of the complexity of the database application system, in order to support the operation of related programs, the database design becomes extremely complex, so the best design can not be achieved overnight, but can only be a process of "repeated exploration and gradual refinement". That is, the process of planning and structured database data objects and the relationship between these data objects.

Characteristics

Database construction is the combination of hardware, software and dry parts.

Three points of technology, seven points of management, twelve points of basic data.

The interface between technology and management is called "dry parts".

Database design should be combined with application system design

Structural (data) design: designing a database framework or database structure

Behavior (processing) design: design applications, transactions, etc.

Design of separation of structure and behavior

Traditional software engineering ignores the analysis and abstraction of data semantics in application, and delays the decision of data structure design whenever possible. The early database design focused on data models and modeling methods, ignoring the design of behavior.
