JSON by PL/SQL

JSON (JavaScript Object Notation) is a lightweight data-interchange format.
It's used for communication with javascript (AJAX).
A introduction to the format can be found here.



A simple JSON object example:

{
    "book": {
        "title": "Hamlet",
        "author": "William Shakespeare",
        "quotes": [
            "Like Niobe, all tears",
            "To be, or not to be",
            "All is not well; I doubt some foul play.",
            "A countenance more in sorrow than in anger."
        ]
    }
}
