Research And Implementation Of Task-oriented Application System Customization Framework

With the rapid development of information technology, the diversification ofenvironment and the polytropy of demand, the software is required to have thecapability of adapting the enterprise’s dynamic “task-oriented” changes, while thecontradiction between the software large-scale production and the personality of theenterprise demand is growing, the traditional development pattern can not solve thegenerality and flexibility of the software efficiently.Basing on framework, workflow, component and related theory technology, thepaper researches and implements task-oriented application system customizationframework. The framework uses workflow to describe task flow, component to realizethe encapsulation of specific functions, and provides a range of toolset supportingapplication system customization and task execution. The paper firstly shows the designidea and method, gives frame model and formalized definitions, and points to theworking procedure of the framework supporting task processing. Meanwhile, the paperdescribes the characters in the system, includes customization, data diversity, andcapacity cooperation, then discusses the realization of specific functional modules,analyzes the implementation and working mechanism of the three aspects“workflow-component-task” which support the software system’s customization in theframework.Finally, a typical application is developed to verify the approach and strategyproposed in this paper, and a group of experiments are conducted to verify thefeasibility and collaboration of the framework. Results show that the framework canrealize the field software system customization and support the flexibility of task, meetthe requirement of generality and flexibility.
