+2011-03-03  Ingo Weinzierl <ingo@intevation.de>
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
+	  Changed the method signature of createCollection(). The Backend needs
+	  the ArtifactCollectionFactory to create new instances of artifact
+	  collections.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
+	  Implemented the interface method createCollection().
