A use case model diagram uses text and shapes to represent the relationship between a user and a system. Primarily, use case model diagrams are used to: Visualize the flow and behavior of the system Illustrate the functionality of the system Represent key system user interactions Depending ...
That statement is a true today as it was 25 years ago (when DeMarco wrote the book.) Many believe that DFDs are “cave-man-like” tools. A current rave (for task/function analysis) in the OO culture is Use Cases. But Use Cases are just stripped-down Data Flow Diagrams. Indeed, the...

Use cases are text documents, not diagrams , and use-case modeling is primarily an act of writing text, not drawing. However, the UML defines a use case diagram to illustrate the names of use cases and actors, and their relationships. A Video Clerk who wants to rent a video to a...

INTERSECT and EXCEPT compare two result sets against each other, and return rows in common, or rows that appear in one but not in the other.INTERSECT and EXCEPT are best explained using a Venn diagram. The circles in the diagrams below represent two result sets from the prod...
I explained the USE Method on this page and provided generic examples of metrics. See the example checklists in the left navigation pane for specific operating systems, where tools and metrics to apply the USE Method are suggested.Also see the complementary thread-based methodology, the TSA ...
Part 1explained the basic concepts of networking within vCD(VMware vCloud Director) andPart 2focussed on Network Pools. In the final and 3rd part we will focus on a use case and what happens on the vSphere layer with these different types of vCD networks. I will cover just a single use...
