Design the schema in a team. Deploy the schema on multiple PostgreSQL servers.
DbSchema model is using its copy of schema structure, independent from the PostgreSQL database.
This is a separation between schema design and the database, with numerous advantages:
- Manage Multiple Databases
- Compare and deploy the database schema on multiple PostgreSQL databases. Incremental changes can be applied.
- Model File
- Save the design model including the schema structure to model file, as XML text. The model file can be open from any computer, without PostgreSQL connectivity.
- Work in Team
- The model file can be stored in GIT and shared in a team. Each team member can modify it and commit model changes in GIT. Database administrators can deploy the schema changes on testing or production databases.
- Migration Scripts
- Generate migration scripts from one version of the schema to another by comparing two different model files with two versions of the same schema.
- Offline Design
- Schema can be designed offline, without database connectivity.
