Add Database Schema for Resource Sharing Policies Management Component

[BimsaraBodaragama]

Purpose

Introduce database schema to support resource-sharing policies and their associated attributes. This resolves the requirement for managing organizational resource-sharing capabilities and ensuring consistency across multiple databases.

Goals

Provide robust support for defining, managing, and maintaining resource-sharing policies and their attributes, ensuring compatibility with diverse database systems.

Approach

Created two tables, UM_RESOURCE_SHARING_POLICY and UM_SHARED_RESOURCE_ATTRIBUTES, to store resource-sharing policies and their attributes.
Added primary and foreign keys for referential integrity, with cascading delete support.
Implemented sequences and triggers for automatic ID generation where applicable (DB2, Oracle, PostgreSQL).

Testing

Ensured schema compatibility with DB2, H2, Informix, MSSQL, MySQL, Oracle, Oracle RAC, PostgreSQL, and MySQL Cluster.
