Its usage has grown up in the later years due to the improvement of meta-language definitions and the application of such technologies in order to provide advanced tools for developers especially for code generation and code maintenance. In this paper it is shown the definition and the implementation of a code generator that handles the generation of the database, a persistence layer and a Data Transfer Object layer. The latter enables the access to the database in a session-less connection using a recursive notation for the selections of items to be retrieved. The implementation could help IT-SMEs while (a) creating application from scratch, (b) allowing code reusability, (c) reducing maintenance especially in a cross-platform software integration environment. In the following sections the approach is described in a theoretical formal definition and later a study case will be illustrated. Finally, the reader will find some proposals concerning the meta-notation in UML. %~
