Database data base

In order to meet the needs of multiple users in a certain department and multiple applications, a collection of interconnected data that is organized, stored and used in a computer system according to a certain data model.

Database Systems A system consisting of a database and its management software. The database system is a kind of ideal data processing core organization developed to meet the needs of data processing. The high-speed processing power and mass storage of computers provide the conditions for automating data management.

The database system is generally composed of four parts: Database, that is, the collection of relevant data stored by He Xiefeng on tapes, magnetic disks, optical disks or other external media, organized together according to a certain structure. Database Management System (DBMS).

It is a set of program systems that can describe, manage, and maintain databases. It follows a common and controlled approach to inserting new data, modifying and retrieving old data. Database Administrator (DBA).

Users and Applications. The basic requirements for the database system are: to be able to guarantee the independence of data.

The independence of data and programs is conducive to speeding up software development and saving development costs. There is less redundant data and a high degree of data sharing. The user interface of the system is simple, easy for users to grasp and easy to use.

It can ensure that the system runs reliably and can be quickly eliminated when there is a failure; Ability to protect data from unauthorized access or destruction; Error data can be prevented, and once it is generated, it can be detected in time. It has the ability to reorganize data, and can change the storage structure or data storage location of data to adapt to the changes in user operation characteristics, and improve the situation of data organization fragmentation and spatiotemporal performance deterioration caused by frequent insertion and deletion operations. It is modifiable and extensible.

It can fully describe the intrinsic relationship between data.
