Research And Extention Of DotNetNuke Framework In .NET Web Application Development

.NET is a very good technology or platform for developing enterprise application. Its connotation is extremely rich; the use crowd is also very huge.As proved, .NET can actually provides formidable technical support for the complex enterprise application. At present, many Open Source .NET development frameworks emerge continuously, and have provided our development work strong support. DotNetNuke is one quite new Open Source framework. Very few project can provide such powerful foundation construction for .NET development like DotNetNuke, simultaneously has provided rich practical classes and expansion functions. DotNetNuke is like the groundsill of a huge construction, has provided stably, reliable safeguard for the entire project; At the same time, not only this framework can provide help in some details for us, but also make the whole .NET project with very high flexibility in the overall situation. The framework can make realization of project much simpler, more efficiently, and produce more concise code.This article take the project -- The National Nucleus Emergency response System Software Platform which the author participates in as the background, carried on a more thorough analysis to the DotNetNuke framework, and studied the N-tier architecture of the framework, the data accessing strategy, processing flow and the core Design Pattern. On this foundation, realized the system using DotNetNuke framework, demonstrated the role which DotNetNuke plays to enhance development efficiency.
