# SQL initialisation

The sql-files in this folder initialize the ZITADEL database and user. These objects need to exist before ZITADEL is able to set and start up.

## files

- 01_user.sql: create the user zitadel uses to connect to the database
- 02_database.sql: create the database for zitadel
- 03_grant_user.sql: grants the user created before to have full access to its database. The user needs full access to the database because zitadel makes ddl/dml on runtime
- 04_eventstore.sql: creates the schema needed for eventsourcing
- 05_projections.sql: creates the schema needed to read the data
- 06_system.sql: creates the schema needed for ZITADEL itself
- 07_encryption_keys_table.sql: creates the table for encryption keys (for event data)
- 08_events_table.sql creates the table for eventsourcing
- 10_unique_constraints_table.sql creates the table to check unique constraints for events
