A LITTLE BIT MORE ABOUT IT

Development &
MobileLightSwitch
“LightSwitch applications use the modern .NET stack of technologies, and
wrap them in an abstraction layer optimized for data management and
maintenance. LightSwitch makes it possible to build data-centric applications
quickly, through visual means.”
“With LightSwitch, you won’t be writing the same code repeatedly to provide data
access functionality or the user interface needed around it. You can write no code,
a little code, or a significant amount – and you can rest assured that it will
be high-value code, rather than mere ‘plumbing’. “

MobileOdata - http://www.odata.org/
OData is a a REST protocol based on existing internet standards including HTTP,
AtomPub, JSON, and hyper-media design patterns.
A main feature of REST APIs is the use of existing HTTP verbs against addressable
resources identified in the URI.
Conceptually, OData is a way of performing database-style CRUD using HTTP verbs
Create : POST
Read: GET
Update: PUT
Delete: DELETE
http://<your application url>/<Service name>.svc/<resource>
