Well, this a testing ambiance that confine the code yet to be tested, alteration and absolute experimentation from the manufacture or archive environment, in the framework of Software Development which includes the Revision Control and the Web Development.

This concept secure the “Live” servers and their data, examination of the source code disposal, and the other bundle of code, content or data, public or proprietary, from the alteration that could be detrimental to a task-critical system or which could easily be reversible. Sandboxes duplicate the minimal functionality which is required for the testing of the program or other code which are under construction. For e.g.: Using the similar environment variable as, or having an access to the database of identical nature, the balanced previously implemented modification was intended to be modified, well there are several opportunities, as the need for the particular functionality would vary strongly with the essence of the code and the applications for which is intended to be.

Sandbox is a concept, which is typically constructed into the Revision Control Software which includes, Subversion (SNV) and CVS, which permits the developers to “Check-Out” a copy of the source code branch or a tree thereof, to inspect and work upon. Post the complete testing of the code by the developer, alteration made in the code of the sandbox should also be updated and checked back and need to be merged with the archive and thereby other developers and the end-users are permitted for the use.

By the further trail of analogy, the phrase “Sandbox” has the application in networking and computing to the other temporary or indefinite confinement regions, which includes the search engine sandboxes and the security sandboxes, which help in the prevention of the incoming data from poignant a “Live” System unless there have not been defined with any criterion or the requirement which need to be fulfilled.
