Custom vs. Off-The-Shelf Architecture

摘要

Members of the COTS-Based System Initiative at the Software Engineering Institute have developed the Generic Enterprise Ensemble (GEE), a generic approach to building distributed, transaction-based, secure enterprise information systems (EIS). GEE is a tool to help in the selection of technologies and architectural choices when building Enterprise Information Systems. Enterprise JavaBeans(TM) (EJB) is a specification from Sun Microsystems for an application server based on Java technology. In this paper, a comparison is made between GEE based solutions and off-the-shelf solutions based on the EJB specification.
