III-COR: Collaborative Research: The Morpheus Data Transformation Management System

本研究项目的目标是通过促进单独构建的数据库的集成，促进跨企业边界的信息共享。因为这样的数据库从来没有相同的内容，所以有必要编写转换（或适配器）来将这样的不同数据转换为公共形式。这种转换的构建被广泛认为是数据集成项目的主要成本。Morpheus项目的目的是通过抓取Web上公开可用的转换并提供高效转换构造的高级工具，在存储库中捕获大量此类转换。此外，强大的浏览工具，使用户能够找到““感兴趣的”“转换迅速在存储库中提供关键字搜索的文件，搜索内的分类层次结构的转换，搜索的出处转换，以及搜索的输入/输出特性。Morpheus有望大幅降低编写和维护数据集成转换的成本，这将缓解未来数据集成项目的难度。该项目将支持马萨诸塞州理工学院和佛罗里达大学的研究生。此外，转换构造将被用作两个机构的数据库课程中的学生练习。可从项目网站http://www.cise.ufl.edu/~jhammer/morpheus/获得进一步的信息，该网站将传播研究成果，并提供原型代码。

The goal of this research project is to facilitate the sharing of information across enterprise boundaries, by facilitating the integration of separately constructed data bases. Because such data bases never have identical content, it is necessary to write transforms (or adaptors) to convert such disparate data into a common form. The construction of such transforms is widely believed to be a major cost of data integration projects. The purpose of the Morpheus project is to capture a large number of such transforms in a repository by crawling the web for publicly available ones and providing high level tools for efficient transform construction. In addition, powerful browsing tools are anticipated that allow users to locate ""interesting"" transforms quickly in the repository by providing keyword search of documentation, search within a classification hierarchy of transforms, search by the provenance of transforms, as well as search by the input/output characteristics. Morpheus is expected to dramatically reduce the cost of writing and maintaining data integration transforms, which will ease the difficulty of future data integration projects. This project will support graduate students at both Massachusetts Institute of Technology and University of Florida. In addition, transform construction will be used as student exercises in data base classes at both institutions.
