Integrating coarse-grained and fine-grained tool integration

The problem of integrating separately written tools so that they work cooperatively, a key issue in computer-aided software engineering (CASE) frameworks, is addressed. An extended object-oriented approach to tool integration that integrates coarse-grained and fine-grained approaches is described. The advantages of both the approaches are discussed, and the techniques by which integration is achieved are described. The approach described addresses both the data and control aspects of tool integration. The keys to the integration are the uniform use of operations and events applied to objects, irrespective of granularity, and the decentralized description of the behavior of classes, permitting independently developed tools to provide separate functionalities for the same objects.<<ETX>>

Hyper/J/spl trade/: multi-dimensional separation of concerns for Java/spl trade/

This paper describes how to accomplish multi-dimensional separation of concerns (MDSOC) with Hyper/J/sup TM/, a tool available for free download, in the context of standard Java/sup TM/ development. Hyper/J does not require any special languages or language variants, compilers, development environments, or processes - it works with standard Java, using any compiler, development environment, methodology and process. It can be used at any stage of the software lifecycle - from design and initial development of code, to the evolution of pre-existing code (whether or not it was developed using Hyper/J), to the adaptation and integration of separately developed components.
