 * History:
 * $Log$
+ * Revision 1.9  2003/12/22 10:19:26  eilers
+ * 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..
+ *
 * Revision 1.8  2003/09/22 14:31:16  eilers
 * Added first experimental incarnation of sql-backend for addressbook.
 * Some modifications to be able to compile the todo sql-backend.
 * A lot of changes fill follow...
 *
 * Revision 1.7  2003/08/01 12:30:16  eilers
 * Merging changes from BRANCH_1_0 to HEAD
 *
 * Revision 1.6.4.1  2003/06/30 14:34:19  eilers
 * Patches from Zecke:
 * Fixing and cleaning up extraMap handling
 * Adding d_ptr for binary compatibility in the future
 *
 * Revision 1.6  2003/04/13 18:07:10  zecke
 * More API doc
 * QString -> const QString&
 * QString = 0l -> QString::null
 *
 * Revision 1.5  2003/02/21 23:31:52  zecke
 * Add XML datebookresource
 * -clean up todoaccessxml header
 * -implement some more stuff in the oeven tester
 * -extend DefaultFactory to not crash and to use datebook
 *
 * -reading of OEvents is working nicely.. saving will be added
 *  tomorrow
 *  -fix spelling in ODateBookAcces
 *
 * Revision 1.4  2002/10/14 15:55:18  eilers
 * Redeactivate SQL.. ;)
 *
 * Revision 1.3  2002/10/10 17:08:58  zecke
 * The Cache is finally in place
 * I tested it with my todolist and it 'works' for 10.000 todos the hits are awesome ;)
 * The read ahead functionality does not make sense for XMLs backends because most of the stuff is already in memory. While using readahead on SQL makes things a lot faster....
 * I still have to fully implement read ahead
 * This change is bic but sc
 *
 * Revision 1.2  2002/10/08 09:27:36  eilers
 * Fixed libopie.pro to include the new pim-API.
 * The SQL-Stuff is currently deactivated. Otherwise everyone who wants to
 * compile itself would need to install libsqlite, libopiesql...
 * Therefore, the backend currently uses XML only..
 *
 * Revision 1.1  2002/10/07 17:35:01  eilers
 * added OBackendFactory for advanced backend access

+ * 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..
+ *
 * Revision 1.3  2003/12/08 15:18:10  eilers
 * Committing unfinished sql implementation before merging to libopie2 starts..
 *
 * Revision 1.2  2003/09/29 07:44:26  eilers
 * Improvement of PIM-SQL Databases, but search queries are still limited.
 * Addressbook: Changed table layout. Now, we just need 1/3 of disk-space.
 * Todo: Started to add new attributes. Some type conversions missing.
 *
 * Revision 1.1  2003/09/22 14:31:16  eilers
 * Added first experimental incarnation of sql-backend for addressbook.
 * Some modifications to be able to compile the todo sql-backend.
 * A lot of changes fill follow...

 * $Log$
+ * Revision 1.2  2003/12/22 10:19:26  eilers
+ * 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..
+ *
 * Revision 1.1  2003/12/08 15:18:12  eilers
 * Committing unfinished sql implementation before merging to libopie2 starts..

 * $Log$
+ * Revision 1.9  2003/12/22 10:19:26  eilers
+ * 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

+ * 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..
+ *
 * Revision 1.8  2003/09/22 14:31:16  eilers
 * Added first experimental incarnation of sql-backend for addressbook.
 * Some modifications to be able to compile the todo sql-backend.
 * A lot of changes fill follow...
 *
 * Revision 1.7  2003/08/01 12:30:16  eilers
 * Merging changes from BRANCH_1_0 to HEAD
 *
 * Revision 1.6.4.1  2003/06/30 14:34:19  eilers
 * Patches from Zecke:
 * Fixing and cleaning up extraMap handling
 * Adding d_ptr for binary compatibility in the future
 *
 * Revision 1.6  2003/04/13 18:07:10  zecke
 * More API doc
 * QString -> const QString&
 * QString = 0l -> QString::null
 *
 * Revision 1.5  2003/02/21 23:31:52  zecke
 * Add XML datebookresource
 * -clean up todoaccessxml header
 * -implement some more stuff in the oeven tester
 * -extend DefaultFactory to not crash and to use datebook
 *
 * -reading of OEvents is working nicely.. saving will be added
 *  tomorrow
 *  -fix spelling in ODateBookAcces
 *
 * Revision 1.4  2002/10/14 15:55:18  eilers
 * Redeactivate SQL.. ;)
 *
 * Revision 1.3  2002/10/10 17:08:58  zecke
 * The Cache is finally in place
 * I tested it with my todolist and it 'works' for 10.000 todos the hits are awesome ;)
 * The read ahead functionality does not make sense for XMLs backends because most of the stuff is already in memory. While using readahead on SQL makes things a lot faster....
 * I still have to fully implement read ahead
 * This change is bic but sc
 *
 * Revision 1.2  2002/10/08 09:27:36  eilers
 * Fixed libopie.pro to include the new pim-API.
 * The SQL-Stuff is currently deactivated. Otherwise everyone who wants to
 * compile itself would need to install libsqlite, libopiesql...
 * Therefore, the backend currently uses XML only..
 *
 * Revision 1.1  2002/10/07 17:35:01  eilers
 * added OBackendFactory for advanced backend access
 *

+ * Revision 1.2  2003/12/22 10:19:26  eilers
+ * 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..
+ *
 * Revision 1.1  2003/12/08 15:18:12  eilers
 * Committing unfinished sql implementation before merging to libopie2 starts..

 * ToDo: Define enum for query settings
 * =====================================================================
 * Version: $Id$
 * =====================================================================
 * History:
 * $Log$
+ * Revision 1.10  2003/12/22 10:19:26  eilers
+ * 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..
+ *
 * Revision 1.9  2003/08/01 12:30:16  eilers
 * Merging changes from BRANCH_1_0 to HEAD
 *
 * Revision 1.8.2.1  2003/06/30 14:34:19  eilers
 * Patches from Zecke:
 * Fixing and cleaning up extraMap handling
 * Adding d_ptr for binary compatibility in the future
 *
 * Revision 1.8  2003/05/08 13:55:09  tille
 * search stuff
 * and match, toRichText & toShortText in oevent
 *
 * Revision 1.7  2003/04/13 18:07:10  zecke
 * More API doc
 * QString -> const QString&
 * QString = 0l -> QString::null
 *
 * Revision 1.6  2003/01/02 14:27:12  eilers
 * Improved query by example: Search by date is possible.. First step
 * for a today plugin for birthdays..
 *
 * Revision 1.5  2002/11/13 14:14:51  eilers
 * Added sorted for Contacts..
 *
 * Revision 1.4  2002/11/01 15:10:42  eilers
 * Added regExp-search in database for all fields in a contact.
 *
 * Revision 1.3  2002/10/16 10:52:40  eilers
 * Added some docu to the interface and now using the cache infrastucture by zecke.. :)
 *
 * Revision 1.2  2002/10/14 16:21:54  eilers
 * Some minor interface updates
 *
 * Revision 1.1  2002/09/27 17:11:44  eilers
 * Added API for accessing the Contact-Database ! It is compiling, but
 * please do not expect that anything is working !
 * I will debug that stuff in the next time ..
 * Please read README_COMPILE for compiling !
