Explain Cyclomatic Complexity
For more complicated programs it is not easy to determine the number of independent paths of the program. McCabe’s cyclomatic complexity defines an upper bound for the number of linearly…

Both activity and state chart diagrams model the dynamic behavior of the system. Activity diagram is essentially a flowchart showing flow of control from activity to activity. A state chart…
A state chart diagram is normally used to model how the state of an object changes in its lifetime. State chart diagrams are good at describing how the behavior of…
Interaction diagrams are models that describe how group of objects collaborate to realize some behavior. Typically, each interaction diagram realizes the behavior of a single use case. An interaction diagram…
UML can be used to construct nine different types of diagrams to capture five different views of a system. Just as a building can be modeled from several views (or…
UML, as the name implies, is a modeling language. It may be used to visualize, specify, construct, and document the artifacts of a software system. It provides a set of…
We are all familiar with the flow chart representation of a program. Flow chart is a convenient technique to represent the flow of control in a program. A structure chart…
A structure chart represents the software architecture, i.e. the various modules making up the system, the dependency (which module calls which other modules), and the parameters that are passed among…
DFD models suffer from several shortcomings. The important limitations of the DFD models are the following:DFDs leave ample scope to be imprecise – In the DFD model, the function performed by…
A data dictionary lists all data items appearing in the DFD model of a system. The data items listed include all data flows and the contents of all data stores…
