早期的信息系统主要是围绕价值链的二级行政流程构建的（例如，会计）。但自从互联网开始使用以来，越来越多的主要流程已经可以实现自动化：客户获取，订购，计费，甚至软件等无形商品的交付。因此，企业中越来越多的部分必须被建模，其中相当大的一部分通常是用面向对象的编程语言（如Java）实现的。为了促进这一复杂的任务，MEMO方法（多视角企业建模）允许从三个层面（战略，组织和信息系统）和四个角度（流程，结构，资源和目标）描述企业。视图的所有部分模型都通过一个共同的面向对象的核心进行集成。在这个框架中，我们提出了一个建模方法的IS层，事件驱动的方法链（EMC）。它是基于事件驱动的过程链（EPC）的Scheer，我们适应适合MEMO方法和面向对象的范式，从而使其适合于基于Web的应用程序的开发。为了说明这一点，我们使用一个软件贸易公司的例子。
Early information systems were mainly built around secondary, administrative processes of the value chain (e.g., accounting). But since the internet came into use, more and more primary processes have become accessible to automation: customer acquisition, ordering, billing and, in the case of intangible goods such as software, even delivery. Hence an increasing part of an enterprise has to be modeled and a substantial part thereof is implemented, usually in an object-oriented programming language like Java. To facilitate this complex task, the MEMO methodology (Multi-perspective Enterprise MOdeling) allows the description of the enterprise on three levels – strategy, organization and information system – and from four angles – process, structure, resources and goals. All partial models for the views are integrated via a common object-oriented core. In this framework we suggest a modeling method for the IS layer, the Event-driven Method Chain (EMC). It is based on the Event-driven Process Chain (EPC) by Scheer, which we adapt to fit both the MEMO methodology and the object-oriented paradigm thus making it suitable for the development of web-based applications. To illustrate this we use the example of a software trading company.
