DotNetNuke:
DotNetNuke is a development framework that enables businesses to quickly build and deploy feature-rich, interactive websites and applications in Microsoft environments. Through an intuitive, menu-driven interface, even non-technical users can use DotNetNuke to easily create new sites or extend the functionality and features of existing web applications.
DotNetNuke evolved from a project called the IBuySpyWorkshop (IBSW.) It was renamed to DotNetNuke to avoid confusion with Microsoft’s portal starter kit, known as IBuySpy Portal. The new name was chosen to reflect the applications .NET (DOTNET) framework, and coupled with the term “nuke” (due to *nuke’s inherent, industry-recognized inclusion in several existing open source portal initiatives.)Professional and Community Editions DNN Corp. offers Professional and Community Editions of DotNetNuke based on the same widely adopted and exhaustive ely tested code base and backed by the same thriving open source community of users, developers, integrators, and vendors. Both Editions are powerful, easy to use, and nearly infinitely scalable.
DotNetNuke Professional Edition is the “certified” version of DotNetNuke Community Edition. In addition to all of the features and functionality of the Community Edition, DotNetNuke Professional Edition includes same-day product support, performance guarantees, and copyright guarantees to ensure indemnification, making it the perfect solution for organizations that intend to use the framework as a core element of their mission-critical web-based communications strategies.
DotNetNuke Community Edition, available for download free of charge, is widely used by administrators who don’t require the additional commercial features available in Professional Edition. Moving from Community Edition to Professional Edition requires no code modification or re-installation
