The objective of (请作答此空) is to determine what parts of the application software will be assigned to what hardware. The major software components of the system being developed have to be identified and then allocated to the various hardware components on which the system will operate. All software systems can be divided into four basic functions. The first is (72). Most information systems require data to be stored and retrieved, whether a small file, such as a memo produced by a word processor, or a large database, such as one that stores an organization's accounting records. The second function is the (73), the processing required to access data, which often means database queries in Structured Query Language. The third function is the (74), which is the logic documented in the DFDs, use cases, and functional requirements. The fourth function is the presentation logic, the display of information to the user and the acceptance of the user's commands. The three primary hardware components of a system are (75).

You work in a company which is named Wiikigo Corp. The company uses SQL Server 2008. You are the administrator of the company database. Now you are in charge of a SQL Server 2008 instance. Now according to the company requirement, you are designing a consolidated repository of performance data. You must make sure that the four requirements below are met: the data collector is used to gather performance information; a single database stores performance information for all instances; performance information that is older than 15 days is deleted; reduce the administrative effort to manage performance to the least. So what action should you perform to achieve this goal? （） A、You should create a SQL Agent job process on each instance to store and delete performance data in a single database for all instances. B、You should configure a management data warehouse process on each instance, then use this process to store and delete performance data in a single database for all instances. C、You should configure an automated server-side trace process on each instance, then use this process to store and delete performance data in a single database for all instances. D、You should create and schedule a single Microsoft SQL Service Integration Services (SSIS) package process, then use this process to store and delete performance data in a single database for all instances.
