Statistical Database Query Languages.

Databases that are mainly used for statistical analysis are called statistical databases (SDB). A statistical database management system (SDBMS) may be defined as a database management system that provides capabilities 1) to model, store, and manipulate data in a manner suitable for the needs of SDB users, and 2) to apply statistical data analysis techniques that range from simple summary statistics to advanced procedures. This paper surveys the existing and proposed SDB data definition and data manipulation (i.e., query) languages. [ABSTRACT FROM AUTHOR]
