Getting website content from different location

Question

I am developing an online accounting project. I do not want to give my code to the clients, but I have to give control of the domain to them. How can I configure the application such that it uses the Database from my client's domain and the application from my own domain ?

For eg : my application domain in www.a.com and my clients domain are b.com, c.com and so on. a.com holds the application source code and b.com holds the database.

Now what I want to do is get the application code from a.com and get database from b.com whenever b.com is opened.

Or is there any other way to achieve it ?

Look into setting a CNAME record through your domain name's administration settings and using sub-domains, perhaps.
