What is a database? -Questions for new users

What is a database ?, J. martin gave a complete definition to the database: the database is a collection of related data stored together. The data is structured and has no harmful or unnecessary redundancy, it also serves a variety of applications. Data Storage is independent of programs that use it. New data is inserted into the database, and the original data can be modified and retrieved in a public and controllable manner. When a system contains several fully separated databases, the system contains a "database set ".

We can fully understand the general meaning of the database from this well-recognized and comprehensive definition. First, the database is the place where data is stored. However, with the development of databases, there is an increasing demand for data operations. People have designed the methods and structures of stored data, that is, the stored data is associated, and structured data. And the data is simplified to the maximum extent until there is no harmful or unnecessary redundancy.

Secondly, the database provides a variety of application services, and the database itself can easily and quickly perform a series of data management such as efficient addition, deletion, modification, and query of data. It can also be said that databases are a collection of related data stored together in an organizational manner to solve specific tasks. In addition, this allows for the automatic management of a large amount of data with the help of computers.

Again, the database can provide data support for many programs and services, and the database is completely independent of the service programs that use it. In this way, data can be perfectly independent and shared.

This is the database we are going to learn. I hope the new contacts will help us.
