TRUE/FALSE
1. Data and information are essentially the same thing.
ANS: F PTS: 1 REF: 5
2. Data processing can be as simple as organizing data to reveal patterns.
ANS: T PTS: 1 REF: 6
3. We are now said to be entering the “knowledge age.”
ANS: T PTS: 1 REF: 6
4. Information implies familiarity, awareness, and understanding knowledge as it applies to an environment.
ANS: F PTS: 1 REF: 6
5. Data constitute the building blocks of information.
ANS: T PTS: 1 REF: 7
6. Metadata present a more complete picture of the data in the database than the data itself.
ANS: T PTS: 1 REF: 7
7. The only way to access the data in a database is through the DBMS.
ANS: T PTS: 1 REF: 7
8. Database programming languages receive all application requests and translate them into the complex operations required to fulfill those requests.
ANS: F PTS: 1 REF: 7
9. The DBMS reveals much of the database’s internal complexity to the application programs and users.
ANS: F PTS: 1 REF: 7
10. One disadvantage of the DBMS is that it increases the risk of data security breaches.
ANS: F PTS: 1 REF: 8
11. An operational database is sometimes referred to as an enterprise database.
ANS: F PTS: 1 REF: 9
12. A data warehouse can store data derived from many sources.
ANS: T PTS: 1 REF: 10
13. The same data might be simultaneously structured and unstructured depending on the intended processing.
ANS: T PTS: 1 REF: 10
14. Corporations use only structured data.
ANS: F PTS: 1 REF: 10
15. Historically, a manual file system was composed of a system of file folders and filing cabinets.
ANS: T PTS: 1 REF: 13
16. Initially the files within a computer file system were similar to manual files.
ANS: T PTS: 1 REF: 14
17. Structural dependence exists when it is possible to make changes in the file structure without affecting the application program’s ability to access the data.
