What method can be utilized in DBMS to identify existing records?

• A. Using a sorting algorithm
• B. Running a dynamic lookup
• C. Creating a validation list
• D. Generating a report

Answer: (B)

The correct choice is running a dynamic lookup, which is a method commonly used in data management systems to identify existing records within a database. This technique involves querying the database in real-time to check for the presence of specific data. A dynamic lookup can efficiently retrieve records based on certain criteria, enabling the application to ascertain whether a record exists or if new data needs to be created. Dynamic lookups are particularly beneficial when dealing with large datasets or when a real-time decision is necessary because they minimize the need for pre-processed data and can adapt to changes in the database instantly. This makes the lookup process not only effective but also responsive to current database states. The other methods mentioned—using a sorting algorithm, creating a validation list, and generating a report—do not achieve the same result as a dynamic lookup. Sorting algorithms are typically used to reorder data rather than identify existing records. Creating a validation list may help in ensuring data integrity, but it is not a direct method for locating existing records in a database. Generating a report can provide a summary of existing records but does not actively interact with the database to identify specific records at the moment of querying. In summary, running a dynamic lookup is specifically designed to identify existing records in a database efficiently and in
