Q: Consider an entity moving from location A to B, while passing several intermediate locations where it will reside for only a relatively short time. When arriving at B, it settles down for a while. Changing an address in a hier- archical location service may still take a relatively long time to complete, and should therefore be avoided when visiting an intermediate location. How can the entity be located at an intermediate location?

Draw the EER diagrams for the following problems using UML notation, Crow’s Foot notation and Chen notation: A large organization has several parking lots, which are used by staff. Each parking lot has a unique name, location, capacity, and number of floors. Each parking lot has parking spaces, which are uniquely identified using a space number. Members of staff can request the use of a parking space. Each member of staff has a unique number, name, telephone extension number, and vehicle registration number. The majority parking spaces are under cover and can be allocated for use by a member of staff for a monthly rate. Parking spaces that are not under cover are free to use when available. Up to twenty covered parking spaces are available for use by visitors to the company. However, only members of staff are able to book out a space for the day of the visit. There is no charge for this type of booking, but the member of staff must provide the visitor’s vehicle license number.

Suppose you had an information/briefing session with college’s Chief Information Officer (CIO) on some of the key use cases of the Campus Access Control System (CACS). The CIO described the process that the student lab-access sub-system goes through to authorise student’s access to the laboratories. Essentially, the lab access sub-system interacts with CACS and retrieves a list of students that are authorised to access a particular lab. If the student who is currently swiping her access card is in this list, then the lab access sub-system will grant access, otherwise access is denied.Use Visual Studio modelling tools to create a Use Case Diagram and a Sequence Diagram for the above process as described.
