ModelRight for DB2: A Complete Guide to ER Modeling and Schema Design
What it is
ModelRight for DB2 is a database modeling tool tailored to design, document, and manage DB2 schemas using entity-relationship (ER) diagrams and forward/reverse engineering workflows.
Key capabilities
- Visual ER diagram editor for entities, relationships, attributes, keys, and constraints.
- Reverse engineering: import existing DB2 schemas into diagrams.
- Forward engineering: generate DB2 DDL scripts from models.
- Synchronization/compare: detect and script differences between model and live DB2 databases.
- Support for DB2-specific features (tablespaces, storage parameters, types) and platform variants.
- Documentation generation (reports, HTML/RTF exports).
- Model versioning and change tracking (depends on edition/integration).
Typical workflows
- Reverse-engineer an existing DB2 database to create a baseline ER model.
- Edit the model visually: add entities, normalize tables, define keys and relationships.
- Validate model rules and referential integrity.
- Generate DDL or change scripts targeted for DB2, review, and deploy.
- Use compare/synchronize to apply incremental changes or keep model and database aligned.
- Export documentation for stakeholders and compliance.
Benefits
- Faster schema design with clear visual representation.
- Reduced deployment errors via generated DDL and compare tooling.
- Easier impact analysis and planning for schema changes.
- Centralized documentation of DB2 data structures.
Limitations & considerations
- Licensing and edition differences affect available features (check vendor docs).
- Complex DB2-specific optimizations may still require manual tuning in generated DDL.
- Integration with CI/CD or version-control may need additional configuration or third-party tools.
Best practices
- Start by reverse-engineering current schemas to capture reality before changing design.
- Use naming standards and consistent conventions in the model.
- Keep small, incremental changes and validate with compare/sync before applying to production.
- Regularly generate and store model documentation and DDL in version control.
- Review generated DDL for DB2-specific performance options (tablespaces, partitioning) before deployment.
When to use it
- Designing new DB2 databases or refactoring existing schemas.
- Teams that need visual modeling, documentation, and script generation.
- Environments where model-to-database synchronization is required.
