Table Data Gateway
Table Data Gateway is a design pattern in software development that provides an object-oriented interface for accessing data in a database table. It acts as a gateway between the application and the database, encapsulating all SQL queries and data access logic for a single table. This pattern simplifies data access by providing methods for common operations like insert, update, delete, and find, making the code more maintainable and testable.
Developers should use Table Data Gateway when building applications that require straightforward, table-centric data access without complex business logic in the data layer. It is particularly useful in scenarios where the database schema is stable and the application primarily performs CRUD (Create, Read, Update, Delete) operations, such as in simple web applications or administrative tools. This pattern helps reduce code duplication and isolates database interactions, improving modularity and easing testing by allowing mock implementations.
