DB2 is an enterprises RDBMS (Relations Database Management System) that offers efficient data safety and high-availability of your precious data. It stores the data in tables. The database tables are further stored in the table space. If the table space gets damaged due to any reason, then all the tables become inaccessible. This behavior causes severe data loss and put you in need of DB2 database recovery solutions if there is no updated backup in place.
