Developed by:
University of Kaiserslautern, FRG D. Wybranietz and P. Buhler

Short Description:
The LADY programming environment has been developed to support the design, implementation, testing, debugging and monitoring of distributed systems with special focus on operating systems. In LADY a distributed system is viewed as a collection of cooperat ing objects connected though typed interfaces. The language offers dynamic modifications of the program structure such as generation and deletion of objects and their interconnections as well as migration and checkpointing of objects. Further Features inc lude the extensibility of programs and recursive definition of objects.

Model: loosely-coupled
Properties: process migration, object-oriented, message passing, lightweight processes
Transparency: location, access, concurrency
Running on: networked MC68000-based systems
Date: 1980 Ð 1985
