Change impact analysis in enterprise-scale heterogeneous systems

许多工业软件系统是用多种编程语言编写的，并利用各种技术在不同的部分之间进行相互通信;我们称这些为异构系统。不幸的是，软件开发工具及其底层分析技术是为在同构环境中运行而创建的;虽然原则上可以为异构系统构建版本，但实际限制出现了：（a）对于语言/技术的新组合的可移植性差，（B）对于更大的异构系统的可扩展性差，以及（c）当对于软件系统的甚至很小的改变必须完全重复昂贵的分析时，较差的可演化性。所有这些问题导致在迁移到企业级异构环境时成本过高，导致工业开发退回到容易出错且效率低下的手动方法。为了解决这些问题，我们提出了四个研究目标：（1）增量维护变更影响分析;（2）异构系统中的模块化依赖分析;（3）快速分析的模块化依赖图的可扩展编码;（4）三个结果之间的集成和工业工具集。我们的工业合作伙伴Find it EZ Software将获得一种新的解决方案，用于支持企业级异构系统的分析，这是该领域其他解决方案所无法解决的。因此，他们的客户（在软件开发行业）将能够更好地修改他们的系统，从而为消费者带来更少的bug和更好的质量。该提案将带来就业机会，并将加拿大打造成软件变更管理“生产力工具”的卓越中心/全球领导者

Many industrial software systems are written in multiple programming languages and leverage varioustechnologies for intercommunicating between the disparate parts; we call these heterogeneous systems. Unfortunately, software development tools and their underlying analysis techniques are created to operate in homogeneous environments; while versions could be built for heterogeneous systems in principle, practical limitations arise: (a) poor portability to novel combinations of languages/technologies, (b) poor scalability to ever larger heterogeneous systems, and (c) poor evolvability when an expensive analysis has to be repeated in its entirety for even small changes to the software system. All these issues lead to prohibitively high costs when moving to enterprise-scale heterogeneous situations, causing industrial development to fall back on error-prone and inefficient manual approaches. To address these issues, we propose to meet four research objectives: (1) incrementally maintainable change impact analysis; (2) modular dependency analyzis in heterogeneous systems; (3) scalable encoding of modularized dependency graphs for fast analysis; and (4) integration between the three results and with an industrial toolset. Our industrial partner, Find it EZ Software, will obtain a novel solution for supporting analysis of enterprise-scale heterogeneous systems, not addressed by other solutions in this space. As a result, their customers (in the software development industrial) will be better able to modify their systems, leading to fewerbugs and better quality for consumers. This proposal will lead to employment opportunities as well as establishing Canada as a center of excellence/global leader in software change management "productivity tools
