Answer 2

Answer:

Data dictionary and transaction log are the two files which are used during operation of the dbms.

Explanation:

• Data Dictionary: A Data Dictionary is a list of names, definitions, and properties for data elements in a database, information system, or research project.
• Transaction log: SQL Server's transaction log is an essential component. Every database contains a transaction log, which is kept separate from the data file in a log file. A transaction log keeps track of all database changes. When a user issues an INSERT, for example, the transaction log records it.
