There are various types of Content Management Systems (CMS) which are widely used for building and managing a website. Although Zen Cart is very good for running an online shop, it cannot be used for building a company website. Your organization may have a website running a CMS, and as you are going to open an online shop, you may need to integrate Zen Cart with that existing CMS. In my book Zen Cart: E-commerce Application Development, I have added an chapter of integrating Zen Cart with several popular content management systems. The publisher of my book, Packt Publishing Limited, has kindly made this chapter available to public. You may like to have a look at it and find your solution for building a shopping application which can be integrated with your existing CMS.
