jSQL is an extension to DDLx, offering a lightweight ORM (Object Relational Mapping) solution that runs on the JDBC v4.3 API. The jSQL framework provides strongly-typed semantics for the SQL language, as well as a cohesive binding to user data models. jSQL uses a SQL schema defined in a DDLx file to create a one-to-one, Object-Model-to-Data-Model API that is vendor agnostic.
