Relationship between Sequence Diagrams and Use Cases in Object-Oriented Development
The Relationship between Sequence Diagrams and Use Cases
In the object-oriented development of a software system, there are supposedly N number of use cases documented in OOA (Object-Oriented Analysis), among which the numbers of brief, casual, and fully dressed use case descriptions are Nb, Nc, and Nf respectively. If the total number of sequence diagrams created in OOD (Object-Oriented Design) is M, let's discuss the relationship between M and N in reference to Nb, Nc, and Nf.
The number of sequence diagrams in OOD is related to the use cases documented in OOA. If each use case has a single sequence diagram, then M = Nb + Nc + Nf.
Explanation
In the development of a software system, the number of sequence diagrams created in Object-Oriented Design (OOD) is related to the number of use cases documented in Object-Oriented Analysis (OOA). The relationship between the total number of sequence diagrams created (M) and the numbers of brief (Nb), casual (Nc), and fully dressed (Nf) use case descriptions can be summarized as:
M = Nb + Nc + Nf
Ultimately, the specific relationship between M and N depends on the design decisions made during the OOD phase.
In the (object-oriented) development of a software system, there are supposedly N number of use cases documented in OOA, among which the numbers of brief, casual, and fully dressed use case descriptions are Nb, Nc, and Nf respectively. If the total number of sequence diagrams created in OOD is M, discuss the relationship between M and N in reference to Nb, Nc, and Nf. The number of sequence diagrams in OOD is related to the use cases documented in OOA. If each use case has a single sequence diagram, then M = Nb + Nc + Nf.
