Row Data Gateway pattern #1312

Open iluwatar opened 4 years ago

iluwatar commented 4 years ago

Description:

The Row Data Gateway pattern provides an object-oriented interface to a single row in a database table, encapsulating the database access logic within a gateway class. This pattern allows for a clear separation between business logic and database operations, enabling more maintainable and testable code.

Main Elements of the Pattern:

  1. Gateway Class: Represents a single row in the database, providing methods for CRUD (Create, Read, Update, Delete) operations.
  2. Database Access Encapsulation: Database queries and updates are encapsulated within the gateway class, abstracting the underlying database interaction.
  3. Separation of Concerns: Business logic is separated from database access logic, promoting clean code architecture.
  4. Consistency: Ensures data consistency by managing row-level data operations through the gateway class.

Acceptance Criteria:

  1. Create a gateway class representing a single row in a database table, with methods for Create, Read, Update, and Delete operations.
  2. Ensure that the gateway class encapsulates all database access logic, separating it from the business logic.
  3. Provide unit tests demonstrating the functionality of the gateway class, including CRUD operations and data consistency.
