1.0 Explanation of Use Case “Use Case” is a system engineering or software term that portrays how a customer or user uses a system to complete a certain task. In other word‚ “Use case” is act as a software modeling method that defines the logic to be implemented and the outcome of the error in the result can be encountered earlier. An interaction between external actors is defined by use cases to attain particular goals. Three main elements that construct a use case are: • Actors: Actors are the

Use Cases are not inherently object-oriented. Why then is use case modelling so important in the Object-Oriented approach? Discuss. Most projects have failed due to the problem of clarity in requirements. Requirements serve as a key part of system development since it is an input to system development and “a system” is produced as the output. Therefore if the requirement stage is wrong‚ the whole system will be wrong. Hence‚ the project fails. Input output Requirements System

ACTIVITY DIAGRAMS IN UML Activity Diagrams WHAT IS AN ACTIVITY DIAGRAM? Activity diagrams consist of activities‚ states and transitions between activities and states. Activity diagrams combine ideas from event diagrams‚ Petri nets and state modeling techniques An activity diagram is a special case of state charts in which most or all states are activity states and most or all transitions are triggered by the completion of activities in the source state. What is an Activity Diagram? The

twin. There are fewer than a dozen documented cases of this type of conjoined twin in the literature. Most infants with this condition are still born‚ or die shortly after birth. Manar was born with this parasitic head‚ but only Manar had a heart and the parasite was feeding of blood of Manar With Manar being recently born her heart is very small and can’t take it. This is affecting her Circulatory System. The circulatory system is an organ system that permits blood and lymph circulation to transport
