Mappings and Relations

By using relations and mappings you can connect your classes with tables. In doing so, you create a bridge between the relational world of database systems and the object-oriented world of Java.

We suggest reading this chapter carefully because the most important foundation of the benefits of working with Signsoft intelliBO is provided here. In this chapter the possible mappings and relations are shown. You can find a lot of examples building on what is explored in this chapter provided in directory /samples of your installation directory.

Please note that the following mapping-examples describe explicitly, how to set the attributes yourself and mostly disregards the default settings described in the JDO specification. Normally your JDO files will look much less complex than in the samples.
