Purpose of Perspectives in SAP HANA Studio

Hi Experts,

I have doubt about SAP HANA Studio Perspectives, What is the purpose of each perspective in SAP HANA SP5(Graphiti ,Debug,Lifecycle Management,Resource,Team Synchronizing,Java,Java Browsing,Java Type Hierarchy,JavaScript,Plug-in Development,SAP HANA Development). I know about Modeler,Admin Console, SAP HANA Development. Please any one tell me about purpose of above mentioned perspectives.

Thanks,
