Use the Repository Reports feature to produce the following reports and matrices, either by printing the reports or by previewing them using your Web browser. The selection criteria from the Repository Reports dialogue box are listed, separated with a slash (/). Explain in a paragraph where the information produced may be effectively used.
What will be an ideal response?
a. Data Flow/Cross-Reference Listing/Data Element/Entire Project
b. Data Flow/Cross-Reference Listing/Data Structure/Entire Project
c. Record Contains Element (One Level) Matrix
d. Data Flow/Single-Entry Listing/Software Master—Normalized
e. Data Flow/Diagram Location Matrix/Data Stores versus Diagrams
f. Data Flow/Composition Matrix/Data Elements versus Data Flows
g. Data Flow/Composition Matrix/Data Elements versus Data Structures
h. Data Flow/Composition Matrix/Data Element versus Data Stores
These reports and matrices will vary depending on the exercises completed by the students. Suggestions for where the information produced could be used are included below.
a. Cross Reference Listing for data elements is useful for determining where each element is used within the system. It is useful for assessing the impact when an element must be changed.
b. Cross Reference Listing for data structures shows where structures are used in the design, and helps to find common structures, such as an address, that may be defined as a group of elements in a program or used as a structure in new screens, reports, or forms.
c. This is the composition matrix. Select Composition Matrix, then Data Elements versus Data Structures. This matrix shows the structures that each element is contained on and the elements found within each structure.
d. The Single Entry Listing, Software Master—Normalized, shows the details for a single entry. It is useful for printing any single entry in the repository.
e. The Data Flow Diagram Location Matrix for data stores shows the diagrams that contain each data store, as well as the data stores found on each diagram. It is useful for assessing proposed changes to a file or database.
f. This matrix shows the elements contained within each data flow and which data flows contain a given element. It is useful for assessing proposed changes to an element, and where the corresponding system design, such as a report, screen, or form, must be changed.
g. This is the same as point c.
h. This matrix shows the elements contained within each data store and which data stores contain a given element. It is useful for assessing proposed changes to an element, and which files must be changed.
