Design And Implementation Of The Schedule Services System

With the system that has massive data query function as main object, focuses on the study of the slow reaction and low performance. In this paper, we use schedule services system to solve the above questions, which supports data tabulation ahead of time.The system can prepare data ahead of schedule in a specified period of time, which called background tasks. All the one-off or Periodic background tasks were background regular tasks, regular tasks for short.Schedule services system not only responses for conducting control and processing, providing flexible regular strategies, but also supervises and records information for the regular tasks. Considering schedule services system from regular tasks, it provides a container for background tasks, and not only handles the tasks but also provides flexible response mechanism.The service has been applied in the information system of Beijing Medicare, which provides a base and assurance of its implementation. The efficiency of modules in statistic business and complex statistics enquiry has greatly increased.This paper describes the main contents in the following aspects:1. The paper gives an introduction about the concept and application field of Schedule Services, especially its research background and the effect on system performance.2. According the characteristics of background tasks and the requirement of system function extension, the needs analysis of the schedule services system has been done.3. The paper gives a preliminary design for the schedule services system, especially on the analysis and design of business processes.4. The paper gives a detailed design for the schedule services system, especially on the analysis and design of the database structure, configuration files structure, classes and methods of the system.5. The function design and code design of the schedule services system.6. To introduce the method of installation, disposition, operation and supervisory control of the schedule services system.
