File Processing System Security Constraints Quiz

Atomicity of updates ensures that either all the database operations in a transaction are executed or none of them are.

Data redundancy refers to the duplication of data within a database or across multiple databases.

Data inconsistency occurs when different versions of the same data yield conflicting results.
