Web SQL DatabaseWeb SQL Database� Databases right in the browser� Around 5MB per domain� Accessible across tabs and windows� Based on SQLite� Features: Transaction, SQL queries

var db = window.openDatabase("NoteTest", "1.0“, "Example DB“, 200000);

3636

var db = window.openDatabase("NoteTest", "1.0“, "Example DB“, 200000);

function saveMe(id, text, timestamp, left, top, zIndex) {db.transaction(function (tx) {tx.executeSql(
