WSO2 EMM provide scripts for installing and configuring MySQL and H2. Each of these databases supports stored procedures, which allow the business logic to be embedded inside the database as an API, providing a powerful mechanism to interact with a relational database. Because these procedures are stored in a precompiled format within the database itself, execution speed is very fast. Client programs can be restricted to access a database via stored procedures only, thereby enforcing fine-grained security, preservation of data integrity, and improved productivity.
The default database of the user manager is the H2 database that comes with WSO2 EMM. You can configure it to point to databases by other vendors such as MySQL, Oracle, PostgreSQL, and Microsoft SQL Servers, using the scripts provided by WSO2 for installing and configuring relational databases. The scripts in the <PRODUCT_HOME>/dbscript/ folder are available in all WSO2 products. They store data related to WSO2 Carbon, on top of which all WSO2 products are built.
The embedded H2 database is suitable for development. However, for most enterprise testing and production environments we recommend an industry-standard RDBMS such as MySQL etc.
