relational query

The MS algebra extends the relational algebra with extended operation semantics, the extended set of operation objects and new algebraic operators that support the statistical analysis queries. MS algebra is a theoretical framework for statistical and scientific database query languages.

二是MS代数包括很多支持统计分析查询的新代数操作，MS代数是构造对用户友好的统计与科学数据库查询语言的理论基础。

Structured Query Language ( SQL): In IBM System and products, a complete full-function, relational database management system with integrated query and report writing facilities.
