Restoring the data from table after deletion

Question

Hi,
If  I delete the data from the database (using delete command) , is there anyway to restore that data. I know it looks bit weird but I'm checking whether there is any technique in abap by which we can restore the data.
Your help would be appreciated.
Thanks,
Kranthi.

Hi Kranthi,
           When you delete lines of a database table using the DELETE command, the process is only complete after a database commit. Before the commit, any database change can be reset using a database rollback.To be able to perform a database rollback, a database system must generate a copy of each database object before making a change. These copies are kept in a rollback log until the end of an LUW. An overflow of the rollback log always results in the termination of the transaction which caused it. For example, attempting to remind a large number of defaulting customers in the same transaction could trigger such an error. You can only solve this problem by dividing the set of database updates into several smaller units ( LUWs) for the database system. You use this statement if you cannot be certain that all the database changes have been executed correctly.
For your information :
An LUW begins each time you start a transaction,when the database changes of the previous LUW have been confirmed (database commit) or when the database changes of the previous LUW have been cancelled (database rollback)
An LUW ends when the database changes have been confirmed (database commit) or when the database changes have been canceled (database rollback). Within an LUW, database changes are not made until after a database commit. Prior to this, any database change can be canceled by a database rollback.
