OGSA-DAI（Open Grid Services Architecture Data Access and Integration）是一个用于构建分布式数据访问和集成系统的框架。直到最近，它还缺乏允许轻松创建分布式数据源联合的内置功能。OGSA-DAI框架的最新版本引入了OGSA-DAI DQP（分布式查询处理）资源。新的资源封装了一个分布式查询处理器，它能够在回答声明性用户查询时编排分布式数据源。查询处理器有许多扩展点，使其易于自定义。我们还引入了一个新的OGSA-DAI Views资源，它为定义关系数据上的视图提供了一种灵活的方法。这两种新资源的互操作性，加上OGSA-DAI框架的灵活性，使得可以构建高度定制的数据集成解决方案。
OGSA-DAI (Open Grid Services Architecture Data Access and Integration) is a framework for building distributed data access and integration systems. Until recently, it lacked the built-in functionality that would allow easy creation of federations of distributed data sources. The latest release of the OGSA-DAI framework introduced the OGSA-DAI DQP (Distributed Query Processing) resource. The new resource encapsulates a distributed query processor, that is able to orchestrate distributed data sources when answering declarative user queries. The query processor has many extensibility points, making it easy to customize. We have also introduced a new OGSA-DAI Views resource that provides a flexible method for defining views over relational data. The interoperability of the two new resources, together with the flexibility of the OGSA-DAI framework, allows the building of highly customized data integration solutions.
