Teradata Warehouse Miner includes a graphical user interface, programmatic Microsoft® .NET interfaces for each analysis, as well as Metadata and Teradata database interfaces. All of these interfaces reside on the client platform and are outlined in this section.
The Teradata Warehouse Miner architecture consists of three logical tiers. The first tier, known as the “User Interface” contains the Teradata Warehouse Miner Graphical User Interface (GUI). The second tier, known as the “Business” tier, contains core Teradata Warehouse Miner analysis components, as well as components that allow access to the Teradata database. The Teradata Database represents the third tier, which is known as the “Database” tier. In addition to running analyses against the database, Teradata Warehouse Miner also uses the database to store information (metadata) about these analyses.
Although the first two tiers execute from a client, they all operate directly against a Teradata system, and are persisted within a metadata model that resides in Teradata. This metadata is a collection of one or more “Analyses” contained within a Teradata Warehouse Miner Data Mining “Project.” The Data Mining Project acts as an index into the metadata, allowing analyses to be created, saved, removed, modified and executed from the Project.
The Teradata Warehouse Miner framework is illustrated graphically below:
