As yet another vendor introduces AJAX to their WCM offering, it’s worth considering what benefits these interfaces bring you. Last year, Jonathan Downes and Joe Walker at CMS Watch provided a great introduction to the subject of Ajax in content management systems, but there are a couple of other points you should consider.

Firstly, in the last year or so, users have become much more familiar with these kinds of interfaces. Most webmail systems make use of the tool and there are countless portal-type sites and map applications that use JavaScript to create smoother browser-based interfaces. This should mean that people will be more comfortable with richer interfaces than with simple web forms.

Secondly, Downes and Walker tell us that Ajax generally equates to better performance. While the interface may give the end-user an impression of efficiency, this isn’t necessarily the case for the server. Remember that with each interaction, you’re sending a request — albeit small — to the server. Given that most CMS licences run on a per CPU basis and many environments have as a consequence been under-specified, introducing these tiny rapid requests could put some serious strain on your hardware and your budget.

These interfaces can be more user-friendly than some client software, but as with any CMS selection process you just need to be wary, size your environment appropriately and test with real editorial users to see if they get the desired usability benefits. It’s pretty safe to say that the smaller the number of users, the more benefit and least risk in deploying these kinds of tools.

A final word of caution: in the Iliad, Ajax was certainly mighty. But he was passed over by his peers for a hero with more guile and ended up destroying himself. Is this the sort of technology you want to unleash in your CMS campaign?
