Data Mining Extensions (DMX) is a query language for Data Mining Models supported by Microsoft's SQL Server Analysis Services product. Like SQL, it supports a data definition language, data manipulation language and a data query language, all three with SQL-like syntax. Whereas SQL statements operate on relational tables, DMX statements operate on data mining models. Similarly, SQL Server supports the MDX language for OLAP databases. DMX is used to create and train data mining models, and to browse, manage, and predict against them. DMX is composed of data definition language (DDL) statements, data manipulation language (DML) statements, and functions and operators. == DMX Queries == DMX Queries are formulated using the SELECT statement.They can extract information from existing data mining models in various ways. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Data Mining Extensions」の詳細全文を読む スポンサード リンク
