Discussion
Which one of the following statements is false?
Answer: B
Correct answer: Data elements in the database can be modified by changing the data dictionary.
The dictionary describes the data; it does not contain it. Editing the description does not change the stored values - changing an element means altering the data itself, through the DBMS. The other three statements are true: the DBA maintains it, it holds the name and description of every element, and it is primarily the DBA’s tool.
