Do you want to save the JSON string directly into DB ? or do you wanna extract the actual data(lets say name, address in your example) from json string and do save? it is very difficult to repopulate the data if you directly saves the data in form of Json. First of all I really do not understand why do you want to explicitly transfer the data specifically in the form of Json. If you use Ajax call($.post on save click in your example), the data is being serialized and sent to the destination where MVC4/Jquery takes care about serialization. Could you explain what is your specific scenario? You can do this simply, if you use MVC4 as below. Still you can use JQUERY calls on post. http://www.asp.net/mvc/tutorials/getting-started-with-ef-using-mvc/implementing-basic-crud-functionality-with-the-entity-framework-in-asp-net-mvc-application Or go through this in specific case. http://www.c-sharpcorner.com/Blogs/14611/ let me know if you need any help, thanks.

It would be better if you can elaborate your question, it is not clear. Where do you want to save? Do you want to convert the retrieved Json to Model and then update to DB?
