Abstract
In a multitenant database, one or more supporting data tables are used to write and store tenant data. Based on the contextual data returning an indication of validity of a detected database transaction, various actions are performed. Data changes may be captured if no valid context is found. At runtime, triggers are used to set a valid context or fix mode context, and database operations causing the data corruptions are captured in a change tracking data structure. The captured data from the database operations include a primary key and an original value for each data change. The original value and primary key for each data change is used to nullify the unintended write.
