Operational databases, also referred to as OLTP On Line Transaction Processing databases, can track warehouse/stock quantities as customers order products from an online web store.
Operational database management systems (also referred to as OLTP On Line Transaction Processing databases), are used to update data in real-time. For example, a company might have an operational database used to track warehouse/stock quantities. As customers order products from an online web store, an operational database can be used to keep track of how many items have been sold and when the company will need to reorder stock.
