RC/Update for Db2

RC/Update for Db2 is architected to provide a comprehensive online interface for managing Db2 objects and data on z/OS. The main system components include: 1. **Online Interface:** Provides a user-friendly interface for executing Db2 commands and managing objects.

2. **RC/Editor:** Enables direct data modification while maintaining referential integrity. 3.

**Data Comparison Engine:** Facilitates data comparison between tables or points in time. 4. **Security Integration Module:** Integrates with z/OS security subsystems (RACF, ACF2, Top Secret) and Db2 authorization.

These components communicate through standard Db2 call interfaces and z/OS system services. The architecture leverages Db2's storage mechanisms and security features. The online interface allows users to execute commands such as `CREATE TABLE`, `ALTER TABLE`, and `DROP TABLE` directly.

Data modifications performed through RC/Editor are validated against referential integrity constraints defined in Db2. Security is enforced through integration with z/OS security, providing authentication and authorization services. Access control is managed through RBAC, leveraging z/OS security roles and Db2 privileges.

Audit logging is integrated with z/OS logging facilities, providing a detailed audit trail of all object changes and data modifications. RC/Update for Db2 enhances productivity by streamlining Db2 administration tasks and reducing the need for manual scripting. It competes with other Db2 management tools by offering a user-friendly online interface and robust data integrity features.
