Software Development Framework

.NET Framework (pronounced dot net) is a software framework developed by Microsoft that runs primarily on Microsoft Windows. It includes a large class library known as Framework Class Library (FCL) and provides language interoperability (each language can use code written in other languages) across several programming languages. Programs written for .NET Framework execute in a software environment (as contrasted to hardware environment), known as Common Language Runtime (CLR), an application virtual machine that provides services such as security, memory management, and exception handling. FCL and CLR together constitute .NET Framework.

FCL provides user interface, data access, database connectivity, cryptography, web application development, numeric algorithms, and network communications. Programmers produce software by combining their own source code with .NET Framework and other libraries. .NET Framework is intended to be used by most new applications created for Windows platform. Microsoft also produces an integrated development environment largely for .NET software called Visual Studio.

Grails is an Open Source, full stack, web application framework for the JVM. Grails is an open source web application framework that uses the Groovy programming language (which is in turn based on the Java platform). It is intended to be a high-productivity framework by following the "coding by convention" paradigm, providing a stand-alone development environment and hiding much of the configuration detail from the developer.[citation needed]

Grails was previously known as 'Groovy on Rails'; in March 2006 that name was dropped in response to a request by David Heinemeier Hansson, founder of the Ruby on Rails framework.[1] Work began in July 2005, with the 0.1 release on March 29, 2006 and the 1.0 release announced on February 18, 2008.

G2One - The Groovy Grails Company - was acquired by SpringSource in November, 2008,[2] and it was later acquired by VMware.[3]

A JDK is required in your Grails development environment. A JRE is not sufficient.

Grails was developed to address a number of goals:

Provide a web framework for the Java platform.

Re-use existing Java technologies such as Hibernate and Spring under a single interface

Offer a consistent development framework.

Offer documentation for key portions of the framework:

The Persistence framework.

Templates using GSP (Groovy Server Pages).

Dynamic tag libraries for creating web page components.

Customizable and extensible Ajax support.

Provide sample applications that demonstrate the framework.

Provide a complete development mode, including a web server and automatic reload of resources.
