You can store your data in Database in your XUL applications. It supports transactions with SQLite. This Javascript class helps developers to communicate with SQLite very easily. It can be used to develop Firefox Add-ons or XUL applications. It uses Components.interfaces.mozIStorageService internally to provide these functionalities.
You can download the SQLite API from here.
Current version is 1.0.0.

Here we will create our first xul application on windows (it is the same in other OS). I expect you know nothing about xul but a bit familiar with javascript, css and xml or html tag format.
first of all download lastest version of xul runner from here or directly from here. At this moment the lastest version is xulrunner-1.9.0.10.en-US.win32.zip. Its important to download the win32 file from runtimes folder not the SDK!

This article shows how easily you can install RoR on windows xp. Using RubyInstaller. I am using windows xp and I installed MySQL previously which I wont talk about right now. Lets start.
1.Get the RubyInstaller
The latest version at this moment is 1.8.6-26 Final (2007-12-14) . Download it and run t. it is going to extract some files by default in c:\ruby which is ok for me. This Installer is going to copy some stuff:
- ruby
- a ruby book ProgrammingRuby.chm in your c:\ruby\doc folder
-
gem ruby plugin manager
-
scite an opensource IDE for ruby

If you do not have installed the RoR (Ruby on Rails) yet, read this article. Here we will create our first "hello world" application and gradually extend it to communicate with database.
Lets create our first project using MySQL configuration
Open the command prompt and find the destination you want to create your project. If you dont know how to use command prompt check . For example I want to create my project in drive D; so I use the following command.
rails --database mysql firstApp

Singleton pattern is a very popular pattern.It is used when you want a unique instance in your application to handle a functionality and it provides you with a common access point to that unique instance.
You can implement Singleton pattern in javascript in different ways. Here we try to design it the way you usually do in object oreinted language such as C#.
