随着数据管理应用程序变得越来越复杂，它们可能需要高效的分布式查询处理，但也需要订阅管理、数据归档等。为了实现这些应用程序，当前的解决方案包括将多个系统堆叠在一起。不同计算模型的并置妨碍了对应用程序进行整体推理，浪费了提高性能的重要机会。
我们提出了一个对AXML [7]语言的简单扩展，允许它声明性地指定和部署仅基于XML和XML查询的复杂应用程序。我们的主要贡献是复杂的分布式AXML计算的一个完整的代数模型。虽然非常有表现力，但该模型在概念上是统一的，并且能够在分布式复杂流程中进行许多强大的优化。
As data management applications grow more complex, they may need efficient distributed query processing, but also subscription management, data archival etc. To enact such applications, the current solution consists of stacking several systems together. The juxtaposition of different computing models prevents reasoning on the application as a whole, and wastes important opportunities to improve performance.
We present a simple extension to the AXML [7] language, allowing it to declaratively specify and deploy complex applications based solely on XML and XML queries. Our main contribution is a full algebraic model for complex distributed AXML computations. While very expressive, the model is conceptually uniform, and enables numerous powerful optimizations across a distributed complex process.
