SPSS Modeler uses a three-tier design. Users manipulate icons and options in the front-end application on Windows operating systems. This front-end client application then communicates with a Clementine Server software, or directly with a database or dataset. The most common configuration in large corporations is to house the Clementine Server software on a powerful analytical server box (Windows, UNIX, Linux), which then connects to the corporate Data warehouse. Data processing commands are automatically converted from the icon-based user interface into a command code (which is not visible) and is sent to the Clementine Server for processing. Where possible, this command code will be further compiled into SQL and processed on the data warehouse.
According to Rexer's Annual Data Miner Survey in 2010: [2]
[This section is not an overview of SPSS, it describes just the SPSS component architecture. An overview is expected to describe what SPSS is, what it does, and why that might be of interest.]
Early versions of the software were Unix based and designed as a consulting tool and not for sale to customers. Originally developed by a UK company named Integral Solutions Limited (ISL), the tool quickly garnered the attention of the data mining community (at that time in its infancy). Original in many respects, it was the first data mining tool to use an icon based Graphical user interface rather than requiring users to write in a Programming language.
In 1999 ISL were acquired by SPSS Inc, who saw the potential for extended development as a commercial data mining tool. In early 2000 the software was developed into a client / server architecture, and shortly afterward the client front-end interface component was completed re-written and replaced with a superior Java front-end.
SPSS Clementine version 12.0 The client front-end runs under Windows. The server back-end Unix variants (Sun, HP-UX, AIX), Linux, and Windows. The graphical user interface is written in Java.
