Abstract
A plurality of database access requests are received at a database system within a designated database access scope. The plurality of database access requests may include a first request to read from a first database table and a second request to write to a second database table. The second request may occur during or after the receipt of the first request. A database access dependency rule linking the first database table and the second database table may be created. The database access dependency rule may impose a protected database access framework when executing a subsequent write request to the second database table when the first database table is updated. The protected database access framework may store one or more values associated with the subsequent write request in a staging table that are capable of being used to undo the subsequent write request.
