Exam 1 - Chapter 1

1) The purpose of a database is to help people keep track of things

2) A possible problem with keeping data in lists is that if you delete a row of data from a list, you may also delete some data items that you want to keep

3) An advantage of keeping data in lists is that if you update a data value in one row of data in a list, other occurrences of the same data item in other rows will be automatically updated as well

4) An advantage of keeping data in lists is that if you add a new row of data to the list, you will never have null values occurring for any data item in the row

5) One problem with storing duplicated data is the potential for inconsistent values

6) A relational database stores data in the form of lists

7) Usually, a database table containing both rows and columns is designed to store data for exactly two themes

8) By separating data into tables containing data on only one theme each, making changes to the data is simplified

9) SQL stands for Structural Question Language

10) Relational database tables are commonly combined, queried, and processed using Structured Query Language (SQL)

11) Although users use database systems, they are not considered part of a database system

12) A database is a set of one or more computer programs that serves as an intermediary between the users and the database management system (DBMS)

13) A relational database can be defined as a self-describing collection of related tables

14) A database is self-describing because the user maintains a record of the database structure outside the database itself

15) Metadata is the user data stored in the database

16) Most organizations create and use their own database management system (DBMS) products

17) The DBMS is used to create the database itself

18) Referential integrity constraints must be enforced by the application program

19) Application programs are responsible for creating, maintaining, and supporting database backup and recovery systems

20) The DBMS receives data update requests from the application program

21) In the general division of labor between database applications and the DBMS, the processing of forms is considered a DBMS task

22) In the general division of labor between database applications and the DBMS, the application program determines which tables need to be modified

23) In the general division of labor between database applications and the DBMS, the application program formats the results of a query into a report

24) Personal DBMS products, such as Microsoft Access, create a clear distinction between the DBMS and the database application

25) There is no reason for serious database developers to learn many aspects of database processing technology because DBMS products like Microsoft Access hide these aspects

26) Microsoft Access 2013 is a personal database that combines a DBMS with an application generator

27) The Microsoft Access 2013 application generator provides the ability to create and store forms, reports, and queries

28) Microsoft Access 2013 databases are stored using the file extension accdb.

29) Microsoft Access 2013 uses the Access 2003 mdb file format as the default file format for database files.

30) Microsoft Access 2013 uses the AutoNumber data type to create surrogate keys

37) Which of the following is not a basic component of a database system? A) Database B) User C) ERD D) DBMS E) Data applications

38) A relational database is: A) a self-describing collection of related tables B) a collection of forms and reports that support a given purpose C) a library of queries and data files for querying D) a set of applications and the data sets for those applications E) a set of metadata

39) The component of a database that makes it self-describing is the: A) related tables B) applications C) library D) data set E) metadata

40) Which of the following would not be an example of database metadata? A) Names of tables in a database B) Properties of tables in a database C) Names of columns in a database and their associated tables D) Properties of columns E) Queries against records in the database tables
