Drop-Downs from Entity Column Entries

Hello,  I was wondering if there is a means to make a drop-down to be derived from the the column entries in a particular entity, as opposed to enumeration? Or to make an enumeration list be updated consistently when a certain entity is updated, I am trying to make orders be completed faster by having drop-downs for part numbers as opposed to manual entry.  Additionally, what is the best way to configure the “orders” entity, because there are times when a order has 5 items, and sometimes 10 line items, what is the best way to store or manage this?  Thank you in advance.
