| With the rapid development of information technology,the requirements of information are increasing.Workflow technology is playing an increasingly important role role in enterprises,campuses and government agencies.The purpose of using workflow technology is to change a series of business processes to task nodes processing and the related process information monitoring.As workflow technology could greatly improve the work efficiency,it is widely used in enterprises.With the increasing process applications,if we continue to use the original embedded methods to develop process applications,not only the process application development efficiency is low and process information is not uniform,so that the development,use and management of the process application is not easy.As a result,how to develop process application using workflow technology has become the research focus.Unified Business Process Center is one of the solutions for the rapid developing and running process applications.In order to realize rapid developing and the use of process applications,this thesis putforward the concept of unified business process center,which has functions of application management,model modeling,process modeling,form modeling and task center that can satisfy the needs process applications.1)In order to improve the usability of the business process center,this thesis designed visual process designer and form designer which can realize the " drag and drop".They can reduce the difficulty of operation in an intuitive way and improve the speed of development process application as well.2)Improve the task data table structure of original workflow system and design push interfaces of task,enabling the process center to develop process applications and integrate the existing process applications to implement the compatibility between different applications.This center can also manage and control all the process applications of schools,companies or government agencies uniformly.3)In terms of database query,this thesis raised a distributed caching scheme which can add a large amount of access data to the cache and reduce the IO operation of the database.4)In the process of examining and approving agency task,the use of asynchronous queue can reduce the pressure on the process center and improve the ability of the system.5)After the analysis of the experimental results,it is concluded that the visual operation will significantly reduce the time of the process and form design.With the use of distributed cache,the load could drop down to 1/3 of the original.The asynchronous queue has solved the problem of batch approval and the unified task center has solved the problem of compatibility between different applications.Experimental results show that the process center can quickly develop process applications and efficiently query and deal with the agency task,which has a high concurrent response capability. |
