作业管理的概念非常重要，目的在于强化操作系统的批处理功能，提供对作业的提交、调度、执行及控制等机制，从而能够更加有效地利用系统资源、平衡网络负载，提高系统的整体性能。 分析了为什么要引入和发展作业管理系统、作业管理系统应该包含的基本功能要素。 基于作业流的作业管理系统具有典型的客户/服务器模型结构，由客户、通讯代理、服务器三层体系结构实现。客户端提供完全的GUI用户界面，完成用户对作业流的管理及对系统的管理功能；通讯代理采用TCP/IP网络通信协议以及与平台无关的数据通讯协议来实现客户与服务器之间的完全通讯；服务器端提供对作业流的全面支持，上层由作业流定义子系统和作业流引擎负责完成对作业流的定义与执行，底层使用网络队列系统来实现对作业的调度与执行，使用户能够最大限度地利用计算机网络系统中的各种资源，以提高执行效率、降低作业成本。

The notion of Job Management is very important, for the purpose of strengthening the batch processing of OS, providing the mechanism of job submitting, scheduling, executing and controlling. Thereby, the system source can be utilized effectively, the network load can be balanced, and the system performance can be improved. This article points out the reasons for developing the JMS, the elementary functional elements of the JMS. The Job Management System based on JobFlow is provided with the typical model structure of C/S, and it is realized by three-layer architecture of Client, Communication Agent and Server. Client supplies complete Graphic User Interface, accomplishing the management of JobFlow and system; Communication agent accomplishes complete communication between client and server by TCP/IP network communication protocol and platform independent data communication protocol; Server supplies full support of JobFlow, The superstratum are the JobFlow Definition Subsystem and JnwEngine, which are responsible for the definition and execution of JobFlow; the understratum is the Network Queue System, which realized the schedule and execution of job, thus all kinds of sources in computer network system can be utilized in order to improve execution efficiency and reduce job cost.
