Today I will be blogging about AJAX. AJAX uses a number of old web technologies, but it has recently become a very hot topic. A number of cool web applications like Google Maps as well as new email services like Windows Live Mail Beta use AJAX. You may even have noticed it in our application when you create an invoice or use a coupon.
AJAX basically allows you to access information from another web address without actually visiting that web address. To me, it means real-time access to our databases. Although AJAX is a very useful technology, it does have a number of short-comings. Browser compatibility and usability are the top two on my list. I will be going into more details about the benefits and drawbacks of Ajax in my next post.
For the time being, here are a few useful links on AJAX. I have separated them into two categories:
