What is real-time data warehousing?

Real-time Data Warehousing refers to systems that reflect the warehouse's status in real-time. When a query is run against the real-time data warehouse to learn about a particular aspect of a business or entity, the answer reflects the state of that entity at the time the query was run. Data warehouses typically have latent data - or data that reflects the business at a past time. Real-time data warehouses provide current data with low latency.
