Mathematica Professional 8.0
Develop
Develop applets, applications, documents, or infrastructure components and systems using Mathematica's unique mix of capabilities--achieving record times on large projects or making small developments practical at all.
Full programming language
Mathematica has a fully featured, modern, symbolic language that enables you to create anything from models and algorithms to complex simulations, from simple macros to complete applications.
Advanced development tools
Write, manage, debug, optimize, and deploy large projects with state-of-the-art Wolfram Workbench development tools. 
System integration support
Mathematica comes with built-in tools for full integration with your existing systems--legacy code, databases, web and grid infrastructures, etc.--acting as a client or a server.
Automated interface construction & Personal development environment
Mathematica 6 brings a revolution in the concept of interactive computing—for the first time allowing dynamic interfaces to be created instantly as a routine part of everyday work. Based on a series of inventions at Wolfram Research, Mathematica 6 builds on Mathematica's powerful core symbolic architecture to allow sophisticated interactive interfaces to be created from single lines of input—as easily as getting answers to simple calculations.
- Manipulate function for creating full-function dynamic interfaces for arbitrary objects.
- Uniform support for manipulating 2D and 3D graphics, math, tables, text, etc.
- Immediate creation of active 1D and 2D sliders, menus, checkboxes, buttons, etc.
- Full integration of controls with graphics objects.
- Real-time computation based on parameter values defined by interactive controls.
- Full integration of all interfaces into scrollable Mathematica notebook documents.
- Automatic support for gamepads and other human interface devices.
- Fully scalable underlying symbolic dynamic Mathematica language system.
- Threaded support for dynamic dependency tracking and updating.
Mathematica 6 makes it practical to build applications for just yourself or an individual colleague, even if it's only for better communicating a single idea.
