摘要：The paper focuses on design patterns applied in software application development. As an application grows in complexity, adding new functionalities or modifying the existing ones becomes a very complicated and time consuming activity. Sometimes, a simple task as searching sections of source-code responsible for some operations will represent a difficult activity if the application consists in a large amount of source code. Thus, the problem of application development becomes a management problem, meaning that it deals with the proper management of complexity. This goal is common with the software development抯 generic goals which include the administration of the continuously growing complexity of business processes. There are some commonly accepted architectures, such as Model View Controller (MVC). We consider that Flex is on a growing popularity trend as Rich Internet Application (RIA) are becoming a standard for web interfaces, therefore the paper抯 intent is to illustrate a possible implementation of MVC for a Flex client without using a standardized MVC framework.
