Liquibase 3.6.x data types mapping table

data type mapping smallDesigning a database, you have to choose data types for columns. It is not neutral which one is used. When you use Liquibase, you use an additional abstraction layer as it has its own data types. They are mapped to data types proper to a specific database engine later during scripts execution process. Choosing a data type, you should keep in mind the final data type on your database engine.
