Research On The Application Of Software Reuse Technology Based On Components

The thinking of software reuse and the application of reuse technology are important to the software industry' development.Software component technology is the core technology that support software reuse,the design,development and use of reusable component can improve software quality,reduce development costs.Although people has been accepted and recognized the importance of software reuse,in practice it has not been widely used,systematize use of software reuse also limited.In software system development,how to meet the growing demand get attention,but rarely consider to build a suitable system for the field of software development with the use of the software component under this premise.First of all,this article from Software Reuse and software Component technology theory approach to study the component-based Software Reuse.In different stages of software development in accordance with the principles of software reuse opportunities to identify reusable chance,which is made into reusable components running on the future development of the software system.Secondly,Component-oriented design system is divided into different levels, through the assembly of functional autonomy of the various business components,to achieve large size and dynamic combination of reusable component.Based on the data components have a stronger ability to adapt changes in demand,that is add to the component,modify it,etc,will not affect the overall operation and performance framework.At last,the information systems development model based on component reuse will guide the overall development of information systems,which is mainly achieve the reuse of information systems analysis,design and realization,while the value extracted with the software reusable components to facilitate the application of other systems in the field.In specific applications,Component-based software reuse is able to solve information integration and interface services in bank CRM,and effective use of bank resources.Through information collection and processing package for the components of modules,to establish for a variety of business functions reusable component library, in accordance with the operational level and the different size requirements,complete software reuse and reconfiguration of system function,then enhance the bank information system capacity.
