Need help with Assumptions and Summary. Please helpme. You will create an Entity Relationship diagram (ERD) from thedatabase design model. This is not as easy as it sounds since whilethere may be a one-to-one correspondence between each databasetable and each entity in the ERD, the logical relationships betweenthe entities in the ERD may well NOT be the same as those betweenthe table in the database table – of necessity every DBMS canimpose implementation constraints on inter-relationships that donot reflect the real life data structure relationships (i.e.exactly what an ERD tries to capture). You will attempt to write acase narrative that describes the data entities as well as theactivities performed in this business situation as supported by thedatabase (you can assume this database is in use by some kind of anorganization) Based on the narrative you wrote you will now createa Swimlane diagram to describe the actors/roles and the flow ofactivities you have inferred. You then make a list of theassumptions (for each diagram) you have made about the case (forexample ) as you developed these models and the case narrative. Youwill then make a list of follow-up question to ask users to fill ingaps in your knowledge about this case in the wake of creating yourmodels. As a team you will check your work for logical consistencyacross the narrative and requirements models you have created,editing where necessary. . . .
