Build an object model for the TIMS system. Some of the details from Jesse’s emails include the following criteria. To summarize, these are your main goals. For the object model for TIMS, start with the JAD summary. If an external entity, such as a student, interacts with the system, then you should identify that entity as an actor – and sketch out (3) use cases that shows the interaction. For each use case, remember to create a use case description, which looks like a table with sections for use case name, actor, description, successful completion, alternatives, preconditions, post-conditions, and assumptions. Next, draw a use case diagram that shows the actors and their actions. Remember to put a system boundary around the diagram so you’ll know what is internal and what is external to the system. • for the object model for TIMS, identify three use cases to demonstrate interaction. For each use case, remember to create a use case description, which looks like a table with sections for use case name, actor, description, successful completion, alternatives, preconditions, post-conditions, and assumptions. • create use case diagram that shows the actors and their actions.
