SSRS on Dynamics AX 2012

Hello Members,

I am a newbie to Dynamics AX 2012. I need to build SSRS reports on Dynamics AX. I have seen several videos which demo the development of SSRS reports using AOT. Is this the only way to design SSRS reports on Dynamics AX 2012? Is there any other optimized way to develop SSRS reports on Dynamics AX ? Is there a meta data database which is related to Dynamics AX which gets stored on SQL Server (like reportserverdb for SSRS) ? Is this metadata db can be used for SSRS report development ? Please guide me to the right resources which will provide this kind of information.

Thanks in advance!!!
