MDX tutorial (Multidimensional expressions), is a syntax which supports the definition and change of multidimensional objects and data. It is similar to the SQL (Structured Query Language). MDX is not a development in the SQL language. It is a fact that MDX can supply some functions but not as well as SQL can. Each MDX query requires a data request like in the SQL query. The example is SELECT clause. Moreover it requires a starting point, example is FROM clause, and a filter, example is WHERE clause.

Actually these keywords are used to fetch information from a cube for the analysis. MDX supplies some robust functions for the change of the data which are fetched. MDX is further extending with user defined functions. Like in the SQL the MDX also includes the data definition language (DDL) syntax which is used to manage data structures. Various MDX commands are there to create and delete the cube, measures, and objects. The purpose of the MDX is to access data from multiple dimensions. MDX tutorial makes it easier and sensitive.

There are most of the languages are used for data definition and manipulation like SQL. It is designed to retrieve the data in row and column. There are tables to represent two dimensional data. Where a row and a column intersect each other the point is called a field. SELECT statement is used in case of the column which is to be retrieved in an SQL query WHERE clause is used in case of the row which is to be retrieved. Multidimensional data means structures which have more than two dimensions.

These structures are called cubes which have multiple dimensions. In a cube where the dimensions intersect each other, there may be many elements of data which is called a measure. It is a complex task to query a simple data of a multidimensional data source. A cube can have multi dimension or only one dimension. If you want to understand the MDX tutorial syntax it is important to understand the concept of the cubes, dimensions, members etc.
