Web-based applications are the de facto platform for distribution of, and interaction with, large-scale data sources. Traditionally these applications had been designed based on the well known 'three-tier architecture'. Invariably, the back-end tier in the architecture would have been implemented as a relational database, providing powerful features for optimization of data queries. Without such features, developing Web applications is much more difficult; leading to increased development time, cost, and decreased responsiveness for end-users.

基于Web的应用程序实际上是大规模数据源的分发和交互平台。传统上，这些应用程序是基于众所周知的“三层架构”设计的。因此，架构中的后端层将被实现为关系数据库，为优化数据查询提供强大的功能。如果没有这些特性，开发Web应用程序就会困难得多;这会导致开发时间和成本增加，并降低最终用户的响应能力。
