Each menu has many menu items, items can appear on multiple menus, and each menu has a price on it. A customer can visit multiple restaurants and a restaurant can have multiple customers. Represent this situation of restaurants with an E-R diagram

LOST offers many different tours. For each tour, the tour name, approximate length (in hours), and fee charged is needed. Guides are identified by an employee ID, but the system should also record a guide's name, home address, and date of hire. Guides take a test to be qualified to lead specific tours. It is important to know which guides are qualified to lead which tours and the date
that they completed the qualification test for each tour. A guide may be qualified to lead many different tours. A tour can have many different qualified guides. New guides may or may not be qualified to lead any tours, just as a new tour may or may not have any qualified guides.

The objective o the analysis is to find what they should seek in a system that allows them to take orders online, at the store, or over the phone.

- The purchasing department handles purchase requests from other departments in the company. People in the company who initiate the original purchase request are the “customers” of the purchasing department. A case worker within the purchasing department receives that request and monitors it until it is ordered and received. Case workers process the requests for purchasing products under $1,500, write a purchase order, and then send it to the approved vendor. Purchase requests over $1,500 must first be sent out for a bid from the vendor that supplies the product. In that case, the purchasing department requests for bid where the vendors participate and the vendors develop their bidding strategy. When the bids return, the case worker selects one bid. Then, the case worker writes a purchase order and sends it to the approved vendor.

Based on your audit plan, the first cycle to audit will be revenue. The first thing you do is document the processes related to receiving and processing the various sources of income. On your initial visit, you were able to observe the following:Once customers have the items to purchase, they head to the register, where a clerk processes the sale. The pharmacy has three cash registers, but does not have an employee who specifically works as a cashier at each one. This provides flexibility in the operation because, of the three employees that the business has, one can collect at any of the cashiers when available. By not having to leave a single person as a cashier, the cashier can focus on providing more direct customer service, refilling merchandise on the shelves, and even assisting in receiving or dispatching…arrow_forward

The sales representative can place a new order for production. If special materials are required for producing the new order, then an order is placed for special materials with the supplier. Otherwise, if no special materials are required for producing the new order or the supplier has finished providing the special materials, the order is added to the production list. Afterwards, the order is scheduled for production. Once the order is confirmed, a letter is generated to the sales representation and to the manager. Draw the activity diagram for the above scenario.arrow_forwardA company makes items. Each item has a name, ID and component quantity. Every item contains many components. Each component can be supplied by one or more suppliers. Suppliers have names and IDS. Each component has ID, name, description, suppliers who supply them, and items in which they are used.
