In this article we’re going to build a simple Login Extension using EclipseLink in place of the default DBManager API provided by SFS2X.
EclipseLink is a powerful ORM (object-relational mapping) framework, that is compliant with the Java Persistence API (JPA) standard.
NOTE: the tutorial presupposes you have an understanding of the basic concepts of object-relational mapping and you’re familiar with at least one database technology. If you don’t have experience with these tools we recommend to check this introduction.
