[amp_mcq option1=”where data is located” option2=”the size of the disk storage device” option3=”It allows a many-to-many relationship” option4=”It is conceptually simple E. It will be the dominant data base of the future” correct=”option1″]
The correct answer is: A. where data is located
A data dictionary is a repository of information about data, including its meaning, origin, usage, and format. It is used to document and manage data in an organization. A data dictionary does not provide information about where data is located, as this information is typically stored in a separate database.
Option B is incorrect because a data dictionary does provide information about the size of the disk storage device. This information is important for planning and managing data storage resources.
Option C is incorrect because a data dictionary does not allow a many-to-many relationship. This type of relationship is not supported by most data dictionaries.
Option D is incorrect because a data dictionary is not conceptually simple. It is a complex system that requires careful design and implementation.
Option E is incorrect because a data dictionary is not necessarily the dominant database of the future. Other types of databases, such as NoSQL databases, may become more popular in the future.
