许多组织已经意识到他们的遗留系统在适应新的技术要求方面的局限性。电子商务应用、平台独立性、预置组件的可重用性、重新配置能力和更高可靠性的趋势促使需要更新目前的系统。因此，通常使用传统方法设计和开发的遗留系统需要重新设计为新的基于组件的系统。这项研究的目的是开发一种方法来比较传统的和基于组件的系统模型。设计科学是用来构建和评估方法的方法。该方法结合和整合了现有的信息系统再工程和概念模型评估方法。实例研究表明，重新构建的基于组件的概念模型能够表示和丰富传统概念模型的所有构造。但是，数据流的使用存在冲突，因为数据流既可以表示事件，也可以表示进程、数据存储和外部代理之间的耦合。因此，该项目派生了一组附加规则，用于在生成基于组件的模型时改进重新设计步骤。
Many organisations have become aware of the limitations of their legacy systems to adapt to new technical requirements. Trends towards e-commerce applications, platform independence, reusability of pre-built components, capacity for reconfiguration and higher reliability have contributed to the need to update current systems. Consequently, legacy systems, typically designed and developed using traditional methods, need to be re-engineered into new component-based systems. The objective of the study is to develop a method to compare traditional and component-based models of systems. Design science is the approach used to build and evaluate the method. The method incorporates and integrates existing methodologies for information systems re-engineering and conceptual model evaluation. A case study illustrating the comparison method revealed that a re-engineered component-based conceptual model was capable of representing and enriching all the traditional conceptual model constructs. However, there was a conflict with the use of data flows as these can represent both events and also couplings between processes, data stores, and external agents. Thus, the project derived an additional set of rules to use when generating a component-based model to improve the re-engineering step.
