UML Diagrams a. Design the UML diagram (activity) for the business case making of placing an order (order, invoice, delivery (fast, regular), payment) -Activity refers to sequence of actions. -The two parts of orders (completion of order and sending the invoice). -The order will be closed only when the product is delivered and paid. -Decision is needed, that has an incoming flow and several outgoing flows. b. Prepare a state diagram for an account. Consider the cases of: overdrawn, account with incorrect PIN, open close. - list the states for the account class - find out the events -from each event consider transition among the states -suspended state: the access to the account is blocked -overdrawn state: when customer withdrawals exceed the balance in the account -start from the normal state

Create a UML Activity Diagram for processing an order. Once an order has been finalized, four parties are involved in processing it: Online Sales, Accounting, Shipping, and Printing. Online Sales receive the order and sends the order to Printing, where the associated PDF file is inspected. If the file is not suitable, a new file is requested from the customer, and the received new file goes for the inspection. Once the file is suitable, Accounting is informed to charge the credit card. While this is done, Printing carries out the actual printing, and sends the result to Shipping. When Shipping has both received the printed products and confirmation from Accounting that payment was successful, the products are shipped to the customer. answer step by step and take screen shoot for your answer
Complete a decomposed lower level data flow diagram (DFD) for the following requirements for a customer posting payment to a store charge account. This is done by scratch using Microsoft Visio and based on the Gane and Sarson shapes as explained in the lesson and textbook (Chapter 6). The customer will send payment by mail and the payment will be posted through the system that updates the customer charge account. The payments have to be deposited systematically to the bank, recorded in the general ledger by the system, and the system should automatically send the customer a receipt. Your DFD should have two external entities, two data stores, and three processes. You should utilize Microsoft Visio to create this DFD.

Draw a complete ER-diagram for the following case. A lecturer (having an ID, name and room number) is responsible for organizing a number of course modules. Each module has a unique code and also a name and each module can involve a number of lectures who deliver part of it. A module is composed of a series of lectures and sometimes lectures a on a given topic can be part of more than one module. A lecture has a time room and date and is delivered by a lecturer and a lecturer may deliver more than one lecture. Students, identified by number and name, can attend lectures and a student must be registered for a number of modules. We also store the date on which the student first registered for that module. Finally, a lecturer acts as a tutor for a number of students and each student has only one tutor. Also show relational database schema including Primary and Foreign key constraints.

Q1. Draw an E-R Diagram for the following situation. At the university system each STUDENT must be assigned an ADVISOR who counsels students about degree requirements and helps students register for classes (COURSE). Each student must register (REGISTRATION) for classes with the help of an advisor, but if the student's assigned advisor is not available, the students may register with any advisor, We must keep track of students, the assigned advisor for each, and the name of the advisor with whom the students registered for the current term.

Attributes of COURSE include Course ID (the identifier), Title, and Credits. Attributes of REGISTRATION include Semester, and Year. Based on your background, think of logical and standard relationships between the given entities.
Develop a context diagram and level-0 diagram for following case study: “Drugstore at Combined Military Hospital fills medical prescriptions for all hospital patients and distributes these medications to the nurse sections responsible for the patients’ care. Doctors write prescriptions and send them to the drugstore. A drugstore technician reviews each prescription and sends it to the appropriate drugstore section. Prescriptions for drugs that must be formulated within the hospital are sent to the lab section, prescriptions for off-the-shelf drugs are sent to the LP (local purchase) section, and prescriptions for narcotics are sent to the LP (local purchase) section. At each section, a pharmacist reviews the order, checks the patient’s file to determine the appropriateness of the prescription, and fills the order if the dosage is at a safe level and it will not negatively interact with the other medications or allergies indicated in the patient’s file. If the pharmacist does not fill…
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.…

A consultancy firm provides consultancy, outsourcing, and interim management services. The firm considers acquisition of projects as part of those services. Acquisition can both be done for existing clients and for new clients, because it concerns acquisition of projects rather than clients. Acquisition is typically started at ‘networking events’ by partners of the consultancy firm. It is handled according to a fixed procedure, but no standard document is used. When a client shows interest in a consultancy service, an intake is done with the client. To maintain a long-term relationship with clients as much as possible, the firm will always try to establish a framework contract with new clients during the intake. For existing clients a framework contract does not have to be established. As another form of relationship management, regular meetings are held with existing clients. During these meetings the client’s organization is discussed with the client. This enables the client to…
