Finishing implementation of sql-backend for datebook. But I have to

port the PIM datebook application to use it, before I could debug the
whole stuff.
Thus, PIM-Database backend is finished, but highly experimental. And some
parts are still generic. For instance, the "queryByExample()" methods are
not (or not fully) implemented. Todo: custom-entries not stored.
The big show stopper: matchRegExp() (needed by OpieSearch) needs regular
expression search in the database, which is not supported by sqlite !
Therefore we need either an extended sqlite or a workaround which would
be very slow and memory consuming..

+ * Finishing implementation of sql-backend for datebook. But I have to
+ * port the PIM datebook application to use it, before I could debug the
+ * whole stuff.
+ * Thus, PIM-Database backend is finished, but highly experimental. And some
+ * parts are still generic. For instance, the "queryByExample()" methods are
+ * not (or not fully) implemented. Todo: custom-entries not stored.
+ * The big show stopper: matchRegExp() (needed by OpieSearch) needs regular
+ * expression search in the database, which is not supported by sqlite !
+ * Therefore we need either an extended sqlite or a workaround which would
+ * be very slow and memory consuming..
