The whole system became a programmed in the computer language TCL (tool Command Language). TCL is interpretative and string based computer language and characterizes itself by a simple syntax and a simple extensinability. These qualities it ideally for glue together of other specialized components (mostly libraries which are written in other languages (C, C ++)). The language becomes often for purposesRapidly Developments Prototypings Tcl uses a brilliant, simple syntax. The following additional components of the TCL were used. Although Tcl is a script language, the Tcl-applications are much faster than Java-programs and use very little resources. The object-oreinted implementing was possible by using XOTcl extension. This makes possible a clear structuralisation of the program.
[ Tk and Tix] a library for developing GUIs (Widgetset).
[TclX] Extended TCL
[ Mysqltcl pgtcl] interfaces to Mysql and Postgresql to relational databasess.
