Consistency or data in DBMS


Consistency - data in DBMS(Database) is accurate in modeling real world, follows integrity constraints
User may ensure transaction consistent by itself
If DBMS is consistent before transaction then it will be after also.

System checks ICs & if they fail, the transaction rolls back (example is aborted).
DBMS enforces some Ics or depending on the ICs declared in CREATE TABLE statements.
DBMS does not understand the semantics of the data.
