• Develop an Context Diagram to model the following description given by the Head of the Centre for Professional Development (CPD) at GTUC: "We make our revenue from training courses. We have courses which we schedule at different locations. Once we have scheduled a course, customers phone in to place bookings for them and we assign instructors to teach the course. Sometimes the person making the bookings is not always the one who will attend the course hence we try to keep track of all the people who are authorized to book places in this way".

- 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 answerA company has various rules for how payments to suppliers are to be authorized.Some payments are in response to an approved purchase order. For approved purchase orders under $5,000, the accountingclerk can immediately issue a check againstthat purchase order and sign the check.

Government Solutions Company (GSC) sells computer equipment to federal government agencies. Whenever a federal agency needs to purchase equipment from GSC, it issues a purchase order against a standing contract previously negotiated with the company.

- James River Jewelry is a small jewelry shop. While James River Jewelry does sell typical jewelry purchased form jewelry vendors, including such items as rings, necklaces, earrings, and watches, it specializes in hard-to-find Asian jewelry. Although some Asian jewelry is manufactured jewelry purchased from vendors in the same manner as the standard jewelry is obtained, many of the Asian jewelry pieces are often unique single items purchased directly from the artisan who created the piece (the term “manufactured” would be an inappropriate description of these pieces). It has a small but loyal clientele, and it wants to further increase customer loyalty by creating a frequent buyer program. In this program, after every 10 purchases, a customer will receive a credit equal to 50 percent of the sum of his or her 10 most recent purchases. This credit must be applied to the next (or “11th”) purchase. Figure D-1 shows data that James River Jewelry collects for its frequent buyer program.…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.
