An Implementation Control/Component by Eiffel Software Inc.

Eiffel Software has streamlined it's product line and now offers 2 versions: EiffelStudio, Enterprise Edition; and EiffelStudio, Free Edition.

The EiffelStudio Enterprise Edition offers a full, rich, expanded feature set and a significantly improved compiler. Using Eiffel's unique features such as Design by Contract^TM and multiple inheritance, you'll be able to create the most robust, reusable and fast applications possible - and you'll do it aided by the new enhancements and additions for version 5.3 that will increase your productivity (and enjoyment).

The EiffelStudio Free Edition has the same compiler and basic features as our Enterprise Edition, without the commercial license and some of the productivity-related tools.

Regardless of the version of EiffelStudio you choose, the Eiffel Development Framework is a rich, thoroughly planned development system - and as such, there are many, many reasons to use EiffelStudio. Here are the top few:

A few of the features of EiffelStudio
Design by Contract
Design by Contract (DBC) is a unique mechanism that demands and simplifies the production of quality software. It ensures that your code will have substantially less errors because it follows "the rules" of development. Our customers tell us that because of DBC they can dramatically lower the number of bugs and spend more time designing. In short it makes programming fun again.

Clean Syntax
You can create easy to read classes with Eiffel's simple, unambiguous plain-English syntax. This greater readability makes the development and maintenance of large and/or multi-participant systems about 10 times easier.

Genericity for .NET
Eiffel genericity allows classes to be written in a way where it can be reused in a multitudeof different scenarios without the need to change any code in the class itself. By employing genericity in your system, you can dr
amatically reduce the amount of bugs and will end up with far less code to maintain throughout the lifecycle of your software.

Multiple Inheritance
Robust multiple inheritance facilities are essential to support combining various abstraction
s and reusable components. The Eiffel-unique mechanisms of renaming (to eliminate name clashes), "join", and "select" (removes ambi
guities from multiple redeclarations) ensure a powerful tool that dramatically improves both modeling and design/implementation.

Fast Executables
Eiffel is very performance-focused, and produces executables that are comparable in speed to C/C++ code with far less development effort or expertise required. Eiffel also employs system-wide optimizations that are not possible with other languages.

Seamless Framework
No more modelling, and then starting over again to design and implement. Eiffel allows you to model bulletproof software, design it, and test it - all in one continuous flow, all within the same tool, all in the same language.

Portability
Allows you to create applications once and run them virtually anywhere. (Not `create once, debug everywhere' as you find in other "multi-platform" solutions.

.NET compatibility
Eiffel is fully .NET compliant, allowing you to create open applications that can interoperate and share code with any other .NET language.

Ideal Migration path to .NET
Eiffel allows you to migrate from another platform (say, Unix) to .NET without having to `freeze' the current application, and without having to create a project so large that it would be totally unmanageable.

Best tool for business critical applications
When you positively need something that will not fail, Eiffel is the ideal choice for a development framework.

Powerful new GUI library
We have entirely redesigned EiffelBuild which gives developers the ability to create powerful multi-platform GUIs that will run identically on any of our supported platforms.

Reusable code
Allows you to shorten development time by a factor of 2 to as much as 10 times.
