ERD and the FlowChart

[smithveg]

Hello,

 

Is there anyone know where can i get the osCommerce ERD and FlowChart Disgram?

I had tried to search in www.oscdoc.com, i found nothing.

I only get the database schema.

 

I had also get a set of ERD actually, i'm not understand about this. The symbol is different from what i learnt.

In this contribution ERD, can anyone tell me what means to crystal symbol between 2 entity.

Which is many, which is one. or many:many, or one:one.

 

Any helps, Thanks
