Essential Database Table Design Principles

The main principles of database table design include the following:

1. Normalization of data tables: Following the principles of database normalization, breaking down data into smaller tables to reduce data redundancy and enhance data consistency.
2. Data uniqueness: ensure that each row of data in the table is unique, avoiding duplicate data.
3. Data integrity: Establish appropriate constraints to ensure the integrity of data, such as primary key constraints, foreign key constraints, unique constraints, etc.
4. The relationship design of the data table involves determining the association between tables based on the relationships between different entities, such as one-to-one, one-to-many, and many-to-many relationships.
5. Name conventions for tables: When naming tables, fields, constraints, etc., follow certain naming conventions to make them easy to understand and maintain.
6. Performance optimization of data tables: when designing data tables, consider the query performance, choose indexes and partitions appropriately, and improve the efficiency of data queries.
7. Scalability of data tables: When designing data tables, consider the potential expansion needs of the system, allocate enough space and fields to make it easier for the system to adjust and modify as the business grows.
