Exam 8: Analyzing Systems Using Data Dictionaries

An !ATTLIST describes an XML attribute in the DTD.

All default elements on an output data flow must be present on a data flow coming into the process.

Which of the following is not contained in the repository?

A data dictionary contains information about a data flow diagram, but not entities or use cases.

What become(s)important for large systems that produce several thousand data elements requiring cataloging and cross-referencing?

Describe the difference between base elements and derived elements.

One of the rules for analyzing a data dictionary is that elements present on a data flow coming or going to a data store must be contained within the data store.

A(n)________ element is one that has a smooth range of values.

There are three standard formats for mainframe computers: zoned decimal, packed decimal, and binary.

What is a reference work of data about data compiled by systems analysts?

The ideal data dictionary is automated, interactive, online, and evolutionary.

When a V is used as a formatting character for an element, it indicates where the decimal point should occur, even though the actual decimal point is not included.

XML is a way to define, sort, filter and translate data into a universal data language.

An XML schema is a more precise way to define the content of an XML document.

Which of the following is a flaw in the system design that is detected by analyzing the data dictionary entries?

________ data structures include additional elements necessary for implementing the system.

A data flow that contains data that are used between processes is called:

(a)Define the term data dictionary.(b)Define metadata.

Parenthesis represent an optional element in the data dictionary.

XML is used when users have different computer (systems)and software.
