True-False Questions 1. Normalizing accounting data refers primarily to eliminating errors and outliers, thus creating ?normal data.? 2. An important reason for normalizing data is to eliminate data redundancy. 3. A flat file is a database with no records. 4. There are exactly three normal forms. 5. Databases cannot store more than one value in the same data field of the same record. 6. A database is in first normal form if all of its record?s data fields are well defined and the information can thus be stored as a flat file. 7. A database is in first normal form if the data it contains is free of errors and outliers. 8. A database is in second normal form if all of its records are in first normal form, and a second, duplicate record exists for each of them. 9. A database is in third normal form if all of its records are in second normal form, and there are no transitive dependencies. 10.

Databases are the same thing as database management systems. 20. A DBMS is an efficient database table in third normal form. 21. When purchasing a new database management system, managers should focus on the system?s technological capabilities rather than its compatibility with current systems. 22.

Database management systems allow their users to create ?input masks? which help to prevent input errors. 27. A database schema is a plan of the entire database. 28. A database subschema is a plot that can often be discovered with forensic accounting. 29. SQL is an example of a database query language. 30. OLAP is notable for its ?drill-down capability.? 31. Online analytical processing enables a computer system to display information that must be computed from the data stored in a database. 32. Pivot tables are powerful statistical tools, but allow the user little flexibility in selecting what data can be analyzed. 33. Object-oriented databases are used to archive older data that management no longer needs to process. 34. Multimedia databases have rendered traditional text databases useless. 35. It is not necessary for data to be ?clean? or accurate if they are stored in a data warehouse. 36. If creating a data mart is not cost effective, management should consider creating a data warehouse, which typically uses less money and time to design. 37. Data warehouses are only used for analyzing current accounting data. 38. Using Microsoft Access, ?referential integrity? enables you to delete a record on the ?one? side of a one-to-many relationship. 39.

Using Microsoft Access to create a select query with multiple criteria (all of which you want satisfied at the same time), you should specify them on the same Criteria line of the query. 43. Using Microsoft Access to create a select query with multiple criteria (all of which you want satisfied at the same time), you should specify them on separate Criteria lines of the query. 44. An OR operation (query) in Microsoft Access requires you to use multiple Criteria lines to create the query. 45. If you wish to create a select query with alternate criteria using Microsoft Access (e.g., you wish to see a list of all customers living in zip codes 12345 or 12366), you should specify them on separate Criteria lines of the query. 46.

A delete query in Microsoft Access is an example of an action query that enables you to delete all those records in a table satisfying specific criteria. 49. It is not necessary to spell accurately or correctly when creating queries in Microsoft Access because such matters as case or spelling are corrected automatically by the system?s spell checker. 50. It is not possible to conduct multi-table queries using Microsoft Access because each table in the system is independent of the others. Multiple-Choice Questions 51.
