Active Record pattern

Description

The Active Record design pattern is a common architectural pattern used to manage database records. It simplifies data access by encapsulating the database logic within a model class. Each instance of the model corresponds to a row in the database, and the model class includes methods for CRUD (Create, Read, Update, Delete) operations.

Main Elements of Active Record Pattern:

1. Model Class: Represents a table in the database. Each instance represents a single row.
2. CRUD Operations: Methods for Create, Read, Update, and Delete operations are defined within the model.
3. Database Connection: The model class manages the database connection.
4. Simple Queries: Basic querying capabilities are encapsulated within the model.

Acceptance Criteria

1. A new model class should be created, representing a database table.
2. The model class should include methods for basic CRUD operations.
3. The implementation should adhere to the project’s contribution guidelines and include relevant documentation and unit tests.

Start by reviewing the repository's contribution guidelines and existing design-pattern implementations to determine where a new Active Record example belongs. Use the issue's model, CRUD, database-connection, documentation, and unit-test criteria as the completion checklist; no specific source file or test is named in the issue.
