Scientific data types show promise for support of scientific computing at all computer system levels, from programming and visualization tasks, through compiler and database technology, to operating systems. Rather than having a distinct data type mechanism at each level, this project concentrates on a coordinated approach across the levels of compiling, data management and operating systems, centered on database support for scientific data types. Key aspects of the project are the development and deployment of a Hybrid Data Manager as a software substrate for rapid experimentation in coordinated data type support across these layers. The HDM uses object-oriented database technology to build a powerful front end for data type instances residing in other storage systems. Existing datasets, as well as newly created objects are to be supported using a staged approach that can lend some support to existing codes while providing full data type support for newly created applications. An important phase of the project is the deployment of the HDM on applications in current use in two scientific domains, computational molecular chemistry and microstructure property predictions in materials science. The experience gained in this project will provide input in the design of a new generation of database systems that will better support the space and modeling demands of scientific applications as well as integrate tightly with compiler and operating system components for increased performance.

科学数据类型显示出支持科学数据的前景 所有计算机系统级别的计算，从编程和 可视化任务，通过编译器和数据库技术， 操作系统.而不是具有不同的数据类型 在每一级的机制，该项目集中在一个 各级汇编、数据和 管理和操作系统，以数据库支持为中心 科学数据类型。该项目的主要方面是 作为软件开发和部署混合数据管理器 用于协调数据类型中快速实验的基片 支持这些层。HDM使用面向对象的 数据库技术来构建一个强大的数据类型前端 存储在其他存储系统中。现有的数据集， 以及新创建的对象将使用 可以为现有代码提供一些支持的分阶段方法 同时为新创建的 应用.项目的一个重要阶段是部署 关于目前在两个科学领域使用的应用程序， 计算分子化学与微结构 材料科学中的性能预测。取得的经验 在这个项目将提供输入的设计一个新的 新一代数据库系统将更好地支持 科学应用的建模需求， 与编译器和操作系统组件紧密集成 以提高性能。
