The Corda platform, and the installed CorDapps store their data in a relational database.
Corda Enterprise supports a range of commercial 3rd party databases: Azure SQL, SQL Server, Oracle and PostgreSQL.
The documentation contains the required database user permission and schema creation steps for production systems for a new Corda installation or database upgrade for upgrading Corda nodes. Database schema updates may be also required when deploying CorDapps on a node or upgrading CorDapps.
For development/testing purposes, the simplified database schema setup for development documentation covers database setup with simplified user permissions. Documentation on understanding the node database explains the differences between both setups.
