Save Time – Business users can quickly access data from multiple sources within a data warehouse, meaning that time won’t be wasted on retrieving data from multiple sources. Boost Confidence – Having data transferred automatically to your data warehouse by a structured system, as opposed to being transferred by human labor, gives you more confidence that your data is clean, current and complete. Increase Insight – Data warehouses structure your data so it’s easily analyzable. Improve Security – Managing who has access to your data is much easier when there’s a centralized connection point. Data warehouses make security completely customizable, so you’re able to give access to whoever you’d like and lock down all of your other systems.
