dbt

dbt uses SQL to model simple batch transformations, while it provides command-line tooling that encourages good engineering practices such as versioning, automated testing and deployment; essentially it implements SQL-based transformation modeling as code. It currently supports multiple data sources, including PostgreSQL.

It the CHT context, dbt runs data tests and migrations for CHT Sync. Once CouchDB data is synchronized and stored in PostgreSQL with CHT Sync, it undergoes transformation using predefined dbt models from the cht-pipeline repository. dbt is used to ingest raw JSON data from the PosgtreSQL database and normalize it into a relational schema to make it easier to query.

You can find more details about CHT data synchronization tools in the related documentation.
