A critical issue for complex component-based systems design is the modeling and analysis of architecture. Architectural specifications of software systems show them as a collection of interrelated components, and constitute what has been called the software architecture level of software design. However, since most of software architecture modeling tools, such as Rational Software Architecture (RSA), run as stand-alone programs, there are still some inconveniency and incapability in fields of team designing and data management. The JArchiDesigner System was designed as efficient, secure, and manageable networking JArchiDesigner system to support collaborative design process. With the JArchiDesigner System, multiple users are able to concurrently access and manipulate the same software architecture information stored in a server machine. This paper discusses the software architecture design and implementation of JArchi- Designer System.
