When I went to school, I talked about the database paradigm in the database. Now I suddenly want to review it. I checked it online and found that it was clearer to myself. First, let's quote a paragraph in Baidu Encyclopedia: The relationships in relational databases must meet certain requirements, that is, they must meet different paradigms. Currently, relational databases have six paradigms: 1nf, 2nf, 3nf, 4nf, and 5nf) and the sixth

Relational Database design paradigm Introduction The relationships in relational databases must meet certain requirements, that is, they must meet different paradigms. Currently, relational databases have six paradigms: 1nf, 2nf, 3nf, 4nf, and 5nf) and the sixth paradigm (6nf ). The first paradigm (1nf) meets the minimum requirements ). The second

The relational database paradigm must follow certain rules to construct a database. In relational databases, this rule is a paradigm. A paradigm is a set of relational patterns at a certain level. The relationships in relational databases must meet certain requirements, that is, they must meet different paradigms. Currently, relational databases have six paradig

Many rules need to be considered during the database establishment process. A good database design not only saves data storage space, facilitates the development of database applications, but also ensures data integrity. Defining a good database requires so many rules, it is not a headache for us to design. Therefore, in order to establish a good database, we must ensure database standardization during development-three major paradigms.Database three paradig
