The editor will share with you the five basic principles of database design. I hope you will gain something after reading this article. Let's discuss it together.

The basic principles of database design: 1, consistency principle to ensure the consistency and validity of data; 2, integrity principle, is the correctness and compatibility of data; 3, security principle; 4, scalability and scalability principle; 5, standardization principle.

Basic principles of database design:

1) consistency principle: unify and systematically analyze and design the data sources, coordinate all kinds of data sources, and ensure the consistency and validity of the data.

2) Integrity principle: the integrity of the database refers to the correctness and compatibility of the data. To prevent legitimate users from adding non-semantic data to the database when using the database. There should be an audit and constraint mechanism for the data input into the database.

3) Security principle: the security of the database refers to protecting the data and preventing illegal users from using the database or legitimate users illegally using the database to cause data leakage, change or destruction. There should be authentication and authorization mechanism.

4) the principle of scalability and expansibility: the design of database structure should fully consider the needs of development and transplantation, and have good expansibility, scalability and moderate redundancy.

5) Standardization principle: the design of database should follow the standardization theory. Standardized database design can reduce exceptions and errors in database insertion, deletion, modification and other operations, and reduce data redundancy.

After reading this article, I believe you have a certain understanding of the "five basic principles of database design". If you want to know more about it, you are welcome to follow the industry information channel. Thank you for reading!
