JSON or Java Script Object Notation was originally created by Douglas Crockford, starting around 2001. It is referred to as JSON because the file extension used is .json.

You can't connect directly from a browser to the database, as the browser doesn't have access.Even if you could, you shouldn't: If your Javascript sends SQL statements to the database, there is nothing stopping a random visitor from having fun by changing your SQL to "drop table", and your entire database is gone.What you do is setting up a server side web service (using PHP, Java servlets, Ruby on Rails or whatever) that accepts a URL, converts it to a DB query and returns the result as JSON. The primary thing from a security standpoint is that you never insert a string from the web into the SQL without validating it first.As an example, you could have something like this:--- browser javascript (using jQuery) ---$.getJSON("/productDetail.json?productId=123", function (data) {// do something with the data});--- server (using Java servlet) ---void doProductDetail(HttpServletRequest req, HttpServletResponse res) {int productId = Integer.parseInt(...); // get product ID from query paramString sql = ...; // generate the SQLString json = ...; // execute query, convert result to JSONres.write(json); // send to browser}
"Marshalling" is roughly the same as "serialization", a mechanism many languages use to take classes, objects and values from a running program and convert them into a (normally binary) format for persistence (write to file or database) or for sending over a network.A stream is a computer science concept meaning that bits are transmitted between a sender and a receiver one chunk at a time, like when sending a file over a network or writing to the hard drive.A marshal stream would be a stream with marshalling data.Marshalling isn't used in Javascript. The JSON serialization format can be considered a similar concept, but JSON differs from marshalling in the sense that JSON is only meant for serializing data, while marshalling in an object oriented language would also transmit the class definition and object methods.Marshalling isn't really required in Javascript, as there is no compilation stage, and you can get the same effect by using eval() on a plain string representation.

Framework is set of reusable software program that forms the basis for an application. Frameworks helps the programmers to build the application quickly. Earlier it was very hard to develop complex web applications. Now its very easy to develop such application using different kinds of frameworks such as Struts, Struts 2, Hibernate, JSF, Tapestry, JUnit, Log4j, Spring etc. In Java technology there are so many frameworks that helps the programmers to build complex applications easily. You can choose these frameworks for building your applications.
JavaScript Object Notation.
JSON is the acronym for JavaScript Object Notation. JSON is primarily used to transmit strutured data information between a server and a webpage. Douglas Crockford is the one is specified this type of format.
The most common record format is probably the JSON (JavaScript Object Notation) format. JSON is widely used for data interchange between systems due to its simplicity, readability, and ease of parsing by various programming languages.

XML is far better for data storage, JSON seems to be used more often for web services, api and the like.
The quickest way to learn JSON with PHP is to check out the following websites: Tutorials Point, W3 Schools, IT Newb, Stack Overflow and many many more.

Javascript allows client-side validation, modifying the designs on css files and also with ajax and jquery allows dynamic exchange of data between client and server. Database, XML files data can be retrieved by use of AJAX dynamically. It also allows manipulation of objects via JSON
