 This module provides relation database support for the `bal persist` feature, which provides functionality to store and query data from a relational database conveniently through a data model instead of using SQL query language.
 
-Currently, this package supports MySQL, MSSQL, PostgreSQL as the relational database. However, we are also planning to add support for other relational databases such as Oracle.
