Database Field Mapping: Step-by-Step Guide

Mapping the fields in a database table refers to associating the fields in the data table with object properties in the application. When setting up field mapping, it typically follows the following steps:

1. To create a new field in a database table: First, you need to determine the field information, including the field name, data type, length, etc.
2. Define objects in the application: Define objects in the application based on the fields of the database table, and set the corresponding properties for the objects, ensuring that the property names correspond to the field names in the database table.
3. Field mapping configuration: In ORM frameworks or database operation tools, setting field mapping by using configuration files or annotations to associate fields in database tables with object properties in the application.
4. Perform data operations: With the help of ORM frameworks or database operation tools, it is possible to directly manipulate data in database tables without the need to write SQL statements. The ORM framework will automatically map fields and convert object properties to database table fields.

In general, field mapping settings associate fields in a database table with object properties in an application to facilitate data interaction between objects and the database.
