Thanks for your kind reply Nathan. I am yet to start development so I shared what I knew before hand with Asp.net + JSON and sql. Finally I am looking to deploy my app on Cloud (AWS or Azure or some other basic cloud so that my customers can use it from anywhere around the world with same performance and speed over the internet). I was initially looking at AJAX + JSON with ASP.NET on front end and oracle at bank end but now i have a SQL guy who can do it better. I could either do JSON front end (with Ajax call with JSON data) -- webservice (convert JSON in .NET Object or Object) and call -- SQL Stored Proc with SQLCommend and Parameters I am looking for a better way to do it since this design is almost 8 years old, toady we have latest and better techs which I may not be well aware of son kindly suggest. cheers varun sharma
