Although several object-oriented distributed systems development tools exist, there is little, if no offer of solutions that homogeneously integrate all aspects of a distributed system. This article describes a toolkit that aims at supporting the construction and the execution of distributed systems. The tools are defined according to an architecture that fully complies with object-oriented principles, providing software developers with a relatively simple, yet effective and efficient, platform that makes the main difficulties normally found in distributed systems development transparent. Among those difficulties, it is the notorious impedance mismatch between the programming language and the object manipulation language. Such difficulty is not noticed in the toolkit presented. Moreover, all the benefits from object orientation are deeply exploited. For this reason, the toolkit permits fast development of distributed systems.
