That is not correct, valgore.
Access 2007 fully supports ULS.
But, the new file format (accdb/accde), which is the format you will want to use if you have a strong desire to use MVF/MVD (Multi Valued Field/Datatype), macros or do extensive interactions with sharepoint, does not support ULS.
There is a distinction between the native databases for Access (Jet/Ace) and MS Access itself (the application, the development tool, ...).
As an aside, Jet 4.0 has always supported more functionality than has been available through the Access interface, say on validation, in the interface, Access supports column level and row level validation (i e, the field validation rule thingie, and what can be found in the table properties, making it possible to validate against another column in the same row). In addition, you can have the Jet engine also perform validation at table level, say for instance to only allow occurrences above average of some column in the same table or another table...
