DaTuM provides a model for technical transformations which follows the familiar pattern of a chain of SQL views.
By providing a chain of data sets, the processing can by followed step by step by basic users of Excel or SQL.
DaTuM has all the required information to generate either VTL or SQL transformations, or transformations in any other technology that follows a pattern of transforming data sets as a Directed Acyclic Graph of functional immutable transformations.
DaTuM also has an advanced mode which can transform data directly from the Logical Data Model concisely using the concepts of Structs and Arrays from SQL 1999.
