Objective Database Abstraction Layer

Objective Database Abstraction Layer, or ODAL, for short , is designed as an Open Source  high-performance multi-purpose database manipulation framework.

The main goal of the project is to create a maintainable, flexible, fast and scalable database abstraction layer with a convenient and simple API.

These goals are achieved by minimizing manual work required to create and maintain the database access layer and consistently applying “separation of concerns” principle. ODAL generates code whenever it is possible out of the database metadata because in the vast majority of projects the database is a given and invariable part created with a different set of tools.

The framework metadata descriptors are the source for code generation of persistent objects, validators, convertors, optionally object trees and its factories. The metadata descriptors, in its turn, are also generated from any JDBC compliant database using provided tool
