- Motivation
- To decouple SQL statement from business objects.
- Summary
- It is an object that acts as a Gateway to a database table. One instance handles all the rows in the table.
- When to Use
- This pattern is obsolete for direct implementation because ORM tools like Entity Frameworks work do this job more effectively.
- Generally used with Domain Model or Table Module to connect with data base.
- I prefer Table Data Gateway when the result set
representation is convenient for the Transaction Script
(110) to work with.
