After reviewing your initial design, the placement office decides to revise the requirements. Make a separate ERD to show your refinements. Refine your original ERD to support the fol lowing new requirements: Allow companies to use their own language to describe positions. The placement office will not maintain a list of standard positions. Allow companies to indicate availability dates and number of openings for positions. Allow companies to reserve blocks of interview time. The interview blocks will not specify times for individual interviews. Rather a company will request a block of X hours during a specified week. Companies reserve interview blocks before the placement office schedules in dividual interviews. Thus, the placement office needs to store interviews as well as interview blocks. Allow students to submit bids for interview blocks. Students receive a set amount of bid dol lars that they can allocate among bids. The bid mechanism is a pseudo-market approach to allocating interviews, a scarce resource. A bid contains a unique bid identifier, a bid amount, and a company. A student can submit many bids and an interview block can receive many bids. 20. For the following problem, define an ERD for the initial requirements and then revise the ERD for the new requirements. Your solution should have an initial ERD, a revised ERD, and a list of design decisions for each ERD. In performing your analysis, you may want to follow the approach presented in Section 6.1. Design a database for managing the task assignments on a work order. A work order records the set of tasks requested by a customer at a specified location. A customer has a unique customer identifier, a name, a billing address (street, city, state, and zip), and a collection of submitted work orders. A work order has a unique work order number, a creation date, a date required, a completion date, an optional supervising employee, a work address (street, city, state, zip), and a set of tasks. Each task has a unique task identifier, a task name, an hourly rate, and estimated hours. Tasks are standardized across work orders so that the same task can be performed on many work or ders. Each task on a work order has a status (not started, in progress, or completed), actual hours, and a completion date. The completion date is not entered until the status changes to complete. After reviewing your initial design, the company decides to revise the requirements. Make a separate ERD to show your refinements. Refine your original ERD to support the following new requirements: The company wants to maintain a list of materials. The data about materials include a unique material identifier, a name, and an estimated cost. A material can appear on multiple work orders. Each work order also has a collection of material requirements. A material requirement in cludes a material, an estimated quantity of the material, and the actual quantity of the material used. The estimated number of hours for a task depends on the work order and task, not on the task alone. Each task of a work order includes an estimated number of hours. 21. For the following problem, define an ERD for the initial requirements and then revise the ERD for the new requirements. Your solution should have an initial ERD, a revised ERD, and a list of design decisions for each ERD. In performing your analysis, you may want to follow the ap proach presented in Section 6.1. Design a database to assist physical plant personnel in managing assignments of keys to employees. The primary purpose of the database is to ensure proper accounting for all keys. An employee has a unique employee number, a name, a position, and an optional office number. A building has a unique building number, a name, and a location within the campus.

Like methods, delegates can also be generic. To declare a generic delegate, use this general form: delegate ret-type delegate-name<type-parameter-list>(arg-list); Notice the placement of the type parameter list. It immediately follows the delegate s name. The advantage of generic delegates is that they let you define, in a type-safe manner, a generalized form that can then be matched to any compatible method. The following program demonstrates a generic delegate called SomeOp that has one type parameter called T. It returns type T and takes an argument of type T.

A cloud application is the software architecture that the cloud uses to eliminate the need to install and run on the client computer. There are many applications that can run, but there needs to be a standard way to connect between the client and the cloud. In this section we ll take a closer look at the protocols that are used to manage connections between both parties.
