Enterprise Distributed Component Object Model's Architecture of the Information System

The paper deals with the analysis of features of Distributed Component Object Model (DCOM) architecture of the information system. DCOM is a distributed software architecture developed by the company Microsoft. With the help of the software component one computer can send messages to program component of another computer, The connection is established automatically. For reliable operation it is required to provide secure connection between connected components, as well as create a system of redirection of traffic. We considered some advantages of DCOM: independence from language; dynamic finding of objects; scalability; open standard; Disadvantages of DCOM are the following : complexity of implementation; dependence on the platform; search through the Active Directory service; the lack of the naming of services through URL. We made the conclusion that Distributed Component Object Model’s architecture of the information system can be used in compatibility with CORBA and the EJB.
