The setup described is common in a point-of-sale system where the 'Items' data store serves as a reference for retail prices during checkout. The 'Item Details' data flow retrieves the retail price for a specific item. It is not necessary for a data store to have both inputs and outputs, and not all processes require both inputs and outputs. It is also not necessary for the data flow to have a verb phrase.
