The link from below (talk2you) brief what ORACLE EBS can do for an enterprise in one single system, from order entry, to inventory, to purchase/procurement, to financial management, to HR/payroll.. you name it.
Basically it touches almost all the business areas in an enterprise.
It is a very powerful system, my opinion( i have no experience with SAP) with lots of potencials.
If you want to learn by yourself, it will be overwhelming at begining.
But, computer system is, at the end, a system with clear architecture and logic. If you able to grab the architecture and logic, you will be close enough.
Business knowledge will be a great asset to support this system as APPS DBA, because you will be able to communicate with all the different interest groups/users groups, and help them understand/utilize the system better.
By saying all this, does not mean you have to know the detail operational business process, but you should know at high level, what is invocie/payment/checks.. what is gl, what is FSG..how they related to each other, for instance
Functional development ( i am not 100% sure about this term here), probably refer to function support(BA). Oracle EBS is a packaged application delivered with certain default/standard business process, which may not 100% cater the customer's requirement. So it is very normal BA will be involved heavily during the design/implementation/testing phase to make sure the system deliveres the results as the organization requires.
Form Developer/Application developer mainly responsible for interface design/development/support, and customization as an extention. This mainly fulfills organization's specific requirement for reports/interfaces.. to run from this system
