Relational-Object Mapping Technique

This paper is focused on describing a technique of creating object-relational transformation components by using code generation system based on database struc-ture. It reviews existing ORM solutions, as well as highlights their main advantages and drawbacks. We describe a technique to create relational-object transformation components by using code generation system to automatically generate persistence layer based on the database structure. Text template engine is used to generate SQL queries, business classes and APIs to access data from application code. Provided default implementations are sufficient to quickly obtain working persistence layer
