RE: Record Locking
Hi Bob
Record Locking in tables takes place whenever someone access a record in a table
This prevents the situation where two users log onto the database, access the same record and begin to change it. This would corrupt the data.
Access uses a database engine (Jet) to avoid data corruption caused by simultaneous updates.
The database engine imposes locks on records as they're edited. A lock notifies the engine that someone is editing the record. It's up to the database engine to appropriately respond to the lock, which prevents data corruption.
So when a user access a record, Jet creates the .LDB file and makes entries in the LDB notifying other copies of Jet of the user's activities.
Hope this helps
