Data Access

The Data Access layer is the API to access the database.

Whenever you change the database schema, the Data Access layer rebuilds the object model, which holds the metadata (information about tables, views, relationships). The schema changes are auto-discovered and cached locally and stored in the system tables.

The Data Access API (OLAPI) has the following features:

It is independent from the database schema

It is “connection-less” which means that it is suitable for mobile applications, access through internet and firewalls.

It is designed with performance and scalability in mind.

It is multi-platform and based in open standards (JDBC, JavaBeans, XML serialization and J2EE/WS).

The SQL API generates the SQL code dynamically.

Supported configuration: MySQL / JBoss. Oracle / Weblogic will be soon available
