Explain the importance of documenting changes in database structure
What will be an ideal response?
Changes in database structure may introduce errors that do not become apparent for long periods of time. Documentation provides a record of changes to assist the investigation into the cause of database errors. Further, documentation of database changes can be used to determine the structure of the database at some point in the past. This is necessary for proper interpretation of any historical records that may need to be retrieved. Finally, documentation can assist in recovering the database from a previous copy in case of database failure. Not only do transactions have to be restored to the recovered database, but also any structural changes since the backup was created will have to be reapplied.
