I have a large, complex 4D structure and I don't want to add any new tables or forms to it. What will 4D Ajax Framework do to my structure?

Nothing. You need to add one component to the application, but the rest of your data structure doesn't need to be touched.

Is a web application built with 4D Ajax Framework meant to replace 4D Client?

Not at all. We've introduced 4D Ajax Framework to give you more choices, not less. Using a web browser as a 4D client is meant to be an additional option to go alongside of using the existing 4D Client.

Why shouldn't I use a free Ajax framework like Dojo or YUI?

There's no reason you can't. However, there are some things that 4DAF does that those other frameworks simply do not offer. For example, we've focused 4D Ajax Framework on providing powerful query handling and data organizing, such as our data tree and calendar controls.

Will the apps I create with 4D Ajax Framework run only on 4D Server, or can I use 4D Runtime Single User?

4D web applications can run on either, as long as you have a copy of 4D Web Server in place.

Can I develop 4D web applications without 4D Ajax Framework?

Yes, of course! We think that once you've tried the tools 4D Ajax Framework has to offer, you'll love them so much that you won't want to do Web development without them, but they are not required in order to develop rich Internet applications with 4D.

4D Web 2.0 Pack is licensed per-developer and is hassle-free for deployment. So which version of the product do I need to buy if I develop on a standalone 4D Developer Edition, but deploy to customers on 4D Server?

4D Web 2.0 Pack is a development tool, so you should buy the version of 4D Web 2.0 Pack that will work with the product you develop with. "Hassle-free" deployment means that you don't have to worry about which version of 4D your customers are using.

I need to buy a 12-month renewal of 4D Web 2.0 Pack before my current subscription expires. What happens if I don't?

If you decide to not continue your subscription, you will still have full access to the version of the software you currently have and it will continue to function. However, you won't have access to any bug fixes, new features, or new parts of the product that we release after your subscription expires.

If you stop subscribing and then decide to resume a subscription after your current one has expired, you can ‘catch-up' by calling your 4D account representative or 4D Customer Service.
