Chapter 3:

1)According to the Semantic Modeling principle, data in an AIS should model:

2. Multiple fields serving to identify a records uniquely are called a:

3. Reference files may be accessed during:

4. A                            file is necessary for batch processing but not for real-time update

5. ASCII:

6. To be meaningful to decision makers data need NOT be:

7. Check digits:

8. In a                         coding scheme, the code used is memorable or suggestive of the item

9. Real-time updating is not practical in conjunction with:

10. Fields in                                        format have variable lengths.

11. According to the general systems model, physical systems must include all of the following except

12. Primary keys must be

13. In the Data Hierarchy, a group of related                                                                   about an individual makes up a record

14. Master files are updated during

15. When records are to be retrieved singly

16. A coding system in which certain ranges of numbers are reserved for each category of the item being coded is called a                                                                                                                                     coding scheme

17. A coding system in which individual digits or groups of digits have meaning is called a coding scheme

18. When records are to be stored:

19. Loosening connections between subsystems is called:
