| Title: cdataport |
| |
| <P>Sometimes it is necessary to recreate a database, copying data from another existing database. For instance, recreating development database instance from production data, etc. While most RDBMS provide data import/export tools, they normally require advanced DBA skills to use and are most often not portable across database engines. Cayenne will provide a lightweight ant task to do data porting between the databases with identical schema, using DataMap information.</P> |
| |
| <P><TT>cdataport</TT> is an Ant task that takes a Cayenne project (cayenne.xml) with at least one DataMap and two DataNodes and ports data from source DataNode to a destination DataNode. All DataMaps linked to either the source or the target DataNode will be considered for porting.</P> |
