IIS-0534404Jayavel Shanmugasundaram [e-mail] UniversityHilda: A High-Level Language for Data Driven Web ApplicationsThis project develops technology to support data-driven Web applications. It is based on Hilda, a new high-level language that addresses some significant shortcomings of current Web application technologies. Hilda provides a uniform data model for the presentation, application and data layers; clear separation of application and presentation logic; support for structured programming driven by the logical structure of the application; and support for application-level conflict resolution.The project produces a Hilda compiler with advanced optimizations, client-server code partitioning, and data caching. It also provides tools to support application integration, testing and schema migration. Using these tools, the project develops several reference Hilda applications including CMS, a new course-management system that will replace a similar conventionally-built system currently being used by several thousand students.Among the broader impacts of this project will be open-source release of the optimizing Hilda compiler and tools, together with a number of substantial applications implemented in Hilda. One of these applications will be CMS; another will be an application to make data collected by the Arecibo radio telescope (http://www.naic.edu) accessible to members of Physics research community and the general public. The development of these Hilda applications will be done primarily by undergraduates, and by high-school students as part of the Ithaca Learning Web program. Project publications, software and results will be made available at http://www.cs.cornell.edu/database/hilda.

IIS-0534404 Jayavel Shanmugasundaram [e-mail] UniversityHilda：A High-Level Language for Data Driven Web Applications这个项目开发支持数据驱动Web应用程序的技术。它基于Hilda，一种新的高级语言，解决了当前Web应用程序技术的一些重大缺陷。Hilda为表示层、应用层和数据层提供统一的数据模型;明确分离应用逻辑和表示逻辑;支持由应用逻辑结构驱动的结构化编程;支持应用级冲突解决。该项目生产的Hilda编译器具有高级优化、客户端-服务器代码分区和数据缓存。 它还提供了支持应用程序集成、测试和模式迁移的工具。使用这些工具，该项目开发了几个参考Hilda应用程序，包括CMS，这是一种新的课程管理系统，将取代目前数千名学生使用的类似传统构建系统。该项目的更广泛影响之一将是开源发布优化Hilda编译器和工具，以及Hilda中实施的许多实质性应用程序。 其中一个应用程序将是CMS;另一个应用程序将使物理研究界成员和公众能够访问阿雷西博射电望远镜收集的数据（http：www.naic.edu）。 这些希尔达应用程序的开发将主要由本科生完成，并由高中学生作为伊萨卡学习网络计划的一部分。项目出版物、软件和成果将在http://www.cs.cornell.edu/database/hilda上提供。
