T 4.28 Loss of data in a database
Loss of data in a database can be caused by a wide variety of factors,
including inadvertent manipulation of data (for example, through
unintentional deletion of data), database crashes and deliberate intrusions.
As a result, the availability and completeness of the data is no longer
guaranteed, and the following consequences might arise:
- Applications which rely on the data in the database can no longer be
executed or offer only partial function..
- The correlation of data is lost.
- Considerable time and effort are required to recover lost data.
Depending on the cause of the data loss, it can be difficult or even impossible
to determine precisely which data has been lost. This can lead to further
financial losses and security risks.
Example:
When a database model is changed, the old tables and structures must first be
saved and deleted. Then the new tables are created. The occurrence of an error
during any of these procedures can easily cause data to be lost or render it
incapable of transfer.
