Q: The Microsoft Access 2013 application generator provides the ability to create and store forms, reports, and queries.

Q: Microsoft Access 2013 is a personal database that combines a DBMS with an application generator.

Q: 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.

Q: Personal DBMS products, such as Microsoft Access, create a clear distinction between the DBMS and the database application.

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

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

Q: In the general division of labor between database applications and the DBMS, the processing of forms is considered a DBMS task.

Q: The DBMS receives data update requests from the application program.

Q: Application programs are responsible for creating, maintaining, and supporting database backup and recovery systems.

Q: Referential integrity constraints must be enforced by the application program.

Q: The DBMS is used to create the database itself.

Q: Most organizations create and use their own database management system (DBMS) products.

Q: Metadata is the user data stored in the database.

Q: A database is self-describing because the user maintains a record of the database structure outside the database itself.

Q: A relational database can be defined as a self-describing collection of related tables.

Q: 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).

Q: Although users use database systems, they are not considered part of a database system.

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

Q: SQL stands for Structural Question Language.

Q: By separating data into tables containing data on only one theme each, making changes to the data is simplified.

Q: Usually, a database table containing both rows and columns is designed to store data for exactly two themes.

Q: A relational database stores data in the form of lists.

Q: One problem with storing duplicated data is the potential for inconsistent values.

Q: 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.

Q: 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.

Q: 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.

Q: The purpose of a database is to help people keep track of things.
