CDO/DB Store

< CDO

The CDO DB store is an implementation of the CDO IStore that allows to store models and meta models in relational databases. It does not use 3rd party components other than database vendor-specific JDBC drivers. The DB store is a proprietary O/R mapper.

Features

Configuration

Annotations

You can define custom mappings on your model by using EAnnotations for DBStore: DBAnnotation.java

In order to optimize the schema on the database, it is recommended that you define the column length, specially when using the data type String.

Example:

 <eStructuralFeatures xsi:type="ecore:EAttribute" name="name" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString">
     <eAnnotations source="http://www.eclipse.org/CDO/DBStore">
         <details key="columnType" value="VARCHAR"/>
         <details key="columnLength" value="255"/>
     </eAnnotations>
 </eStructuralFeatures>
