Which of the following is NOT a method for identifying existing records in DBMS?

• A. Selecting a specific field
• B. Running a dynamic lookup
• C. Using a static database snapshot
• D. Using predefined queries

Answer: (C)

Using a static database snapshot is not a method for identifying existing records in a Database Management System (DBMS). A static snapshot refers to a fixed view of the database at a specific moment in time. It does not update with changes made to the database, which means it can become outdated and miss records added or modified after the snapshot was taken. In contrast, selecting a specific field, running a dynamic lookup, and using predefined queries are all active methods that allow you to identify and retrieve records based on current data in the DBMS. Selecting a specific field allows for pinpointing records based on unique identifiers. A dynamic lookup is a real-time search that updates with the latest information from the database, while predefined queries provide a structured approach to fetching records based on specified criteria. These methods are essential for effectively managing and accessing data within a live database environment.
