Domain specific architecture development for enterprise systems based on common object request broker architecture (CORBA)

摘要

Large business organizations with enterprise wide systems have followed an ad hoc incremental growth pattern. They are either monolithic, that are difficult to replace and maintain, or are components with little or no interoperability between them. Such systems suffer from lack of uniformity and definition in their information technology infrastructure. To migrate from this state, to systems that are extensible, interoperable and non-redundant in functionality it is very important to focus on the architecture. We use the healthcare enterprise system as a case study for the purpose of this thesis. It is indeed difficult, if not impossible to construct the overall architecture of the system without identifying the individual components of the system. Hence we follow an incremental methodology in identifying and developing each component. One such component is Order management, which is an essential component of a healthcare information system that offers enterprise wide functionality.
