1.1. Use case diagram:
- A UML use case diagram is the principal form of system/software requirements for an undeveloped software program. The use case specifies the intended behavior (what) rather than the actual means of achieving it (how). Once defined, use cases can have both written and visual representations (i.e. use case diagram). A crucial aspect of use case modeling is that it allows us to build a system from the standpoint of the end user. By describing all externally observable system behavior, it is an excellent strategy for conveying system behavior in user terms.
