摘要：This article deals with the specification and transformation of distributed systems under Model Driven Architecture (MDA). It reviews basic concepts and benefits of MDA approach, its relations with traditional software development and suggests an alternative method for specification of distributed internet information systems using unified modeling language (UML) notation and transformation of these specifications into program code. Transforma-tion method enables to ease work of the system analyst when creating large and complex information systems. It allows separating full system specification into different parts and converting functions of these parts into platform dependent program code. This article also refers to a synthesis of object interaction diagrams of distributed systems mentioned before.
