Javascript and Database Connectivity

Is it possible for javascript to access a database directly? I feel my question is rhetorical owing to the fact that this is a security issue. But is it possible anyway?

http://www.daniweb.com/web-development/php/threads/197091/update-mysql-table-using-javascript You need to look into the jQuery.ajax function, this will send/receive information from a PHP document.

What you need to do is set up a PHP document that will handle the the form as though it were being posted to by http, or by setting the action on the tag.

You then need to make a function similar to this:

Yes it is.

I don't know more about it but javascript can connect with DB using ADODB.Connection.

Depends on what DB you want to use.

CouchDB is HTTP addressable, so can be hit from JS. http://couchdb.apache.org/

It is possible!
with the new html5 feature, js can connect through WebSql. a live example : http://html5demos.com/database
the syntax is similar to all the other sql wrappers : 

var db = openDatabase('mydb', '1.0', 'my first database', 2 * 1024 * 1024);
db.transaction(function (tx) {
    tx.executeSql('CREATE TABLE foo (id unique, text)');
});

it is currently supported by chrome, safari and opera
here's a tutorial : http://html5doctor.com/introducing-web-sql-databases/

Not from the browser. Javascript can be used on the server to set up server side functionality, though.

No. Setup a server side script which will talk the database and then call this script with AJAX.
