List at least three conditions that contribute to data redundancy and inconsistency. Answer: Data redundancy occurs when different divisions, functional areas, and groups in an organization independently collect the same piece of information. Because it is collected and maintained in so many different places, the same data item may have:
- different meanings in different parts of the organization,
- different names may be used for the same item, and
- different descriptions for the same condition. In addition, the fields into which the data is gathered may have different field names, different attributes, or different constraints.

List and describe three main capabilities or tools of a DBMS. Answer: A data definition capability to specify the structure of the content of the database. This capability would be used to create database tables and to define the characteristics of the fields in each table. A data dictionary to store definitions of data elements in the database and their characteristics. In large corporate databases, the data dictionary may capture additional information, such as usage; ownership; authorization; security; and the individuals, business functions, programs, and reports that use each data element. A data manipulation language, such as SQL, that is used to add, change, delete, and retrieve the data in the database. This language contains commands that permit end users and programming specialists to extract data from the database to satisfy information requests and develop applications.
