IODA architectural pattern

Description

The IODA (Input, Operations, Data, and Access) design pattern focuses on separating the concerns of input, operations, data, and access within a software system. This pattern promotes cleaner, more maintainable code by isolating different aspects of the system, thus making it easier to manage and scale.

Main Elements of the Pattern:

1. Input: Handles all the input operations, including user interactions and data input from external sources.
2. Operations: Manages the business logic and core operations of the application.
3. Data: Responsible for the data management, including data structures and in-memory data handling.
4. Access: Handles the persistence layer, including database interactions and external service integrations.

Acceptance Criteria

1. The implementation should include clearly defined classes or modules for Input, Operations, Data, and Access.
2. Each component should be independently testable, with unit tests covering the core functionalities of Input, Operations, Data, and Access.
3. Ensure adherence to the project's coding standards and contribution guidelines as outlined in the project's documentation.

No target files, entry points, or existing tests are specified. Start by reading the project's contribution guidelines and the referenced IODA architecture material, then identify where a new Java pattern belongs and define independently testable Input, Operations, Data, and Access components with unit-test coverage.
