standard table for keeping record of updation in z tables

hi all,

my problem is that suppose i have a z-table ZXXX with maintanence allowed. now everytime i enter a new record definately some event is triggered . now that event must be a part of a standard business object . can any one tell me the name of the object.

even if some one has knowledge about a standard table which keeps record of tables in which records are updated.

regards
