WSO2 provides scripts for installing and configuring several types of relational databases, including MySQL, IBM DB2, Oracle, and more. Each of these databases supports stored procedures, which allows business logic to be embedded inside the database as an API, providing a powerful mechanism for interacting with a relational database. Because stored procedures are stored in a precompiled format within the database itself, execution speed is much faster. Client programs can be restricted to accessing a database via stored procedures only, thereby enforcing fine-grained security, preservation of data integrity, and improved productivity.

These embedded H2 databases are suitable for development, testing, and some production environments. For most production environments, however, we recommend you to use an industry-standard RDBMS such as Oracle, PostgreSQL, MySQL, MS SQL, etc.
