Microservice pattern: Shared database

[iluwatar]

Description:
The Microservices - Shared Database design pattern involves multiple microservices sharing a single database schema. This pattern can be used to manage distributed data transactions and maintain data consistency across different microservices.

Main elements of the pattern:

• Shared Database: A single database is shared among multiple microservices.
• Data Consistency: Ensuring data consistency and integrity across microservices.
• Transaction Management: Handling distributed transactions efficiently.
• Service Independence: Maintaining the autonomy of each microservice while sharing a common data source.
• Database Schema Design: Careful design of the database schema to avoid tight coupling between microservices.
• Security: Implementing robust security measures to protect the shared data.
• Scalability: Ensuring that the shared database can handle the load from multiple microservices.

Acceptance Criteria:

1. Create a new package for the Microservices - Shared Database design pattern within the project.
2. Implement a working example demonstrating the shared database pattern with at least two microservices.
3. Ensure that the example includes:
   • A shared database schema
   • Transaction management across microservices
   • Data consistency mechanisms
4. Include unit tests and integration tests to validate the functionality.
5. Provide comprehensive documentation explaining the implementation, including code comments and a README file in the package.
6. Ensure the implementation adheres to the project's contribution guidelines and coding standards.
