I'm still learning this stuff myself, but as I understand it the logical system 
components like file systems, database storage and shares tend to rely upon 
hardware system components like disk drives.  That reliance might be handled by 
an intermediary, though, like a storage management application that wraps the 
details inside an abstraction.

If you get the white paper, it helps a lot.  8)

But this would not be stored in the SystemStorage table right?  I store the 
applications as products.

        I'm not sure if MS Exchange shows up as a product or package, but I am 
pretty sure it shows up as one of them for the 'installed' nature of the 
software and as applications and software servers for their 'running' nature.  
The white paper has us using the 'hosted system component' type of dependency 
relationship to hook the 'installed' stuff to their related computer systems.
        
        For databases, remember that the concept of a database is somewhat 
virtual.  The data is organized in a logical fashion by the software server, 
but it lives on storage units that might not be in the same physical machine.  
I was taught to use the database storage instances to represent what is going 
on at the hardware level while the database instances show things at the 
logical level.

        Hi All,
        
        Would software that runs independently such as MS Exchange be 
classified as a "Hosted System component" or a "Component" of a Server_ABC? I 
did research and I am not sure what the impact would be upon selecting either 
option.  
        
        A co-worker also created database instances under the SystemSoftware 
table - not sure why? I thought it would be in the AST:Database or 
AST:DatabaseStorage table. Should database such as Oracle be stored in the 
AST:Databasestorage table and the instance under AST:Database?
