A data warehouse is an archive of historical data that enables analysts to compare data from different sources to draw actionable conclusions. A data warehouse can be deployed on the premises or in a cloud. Which option you choose is contingent on your business’s needs and other considerations such as scalability, cost resources, control, and security.
Data warehouses are used to store large amounts of historical data from an organization and to perform in-depth analysis for business intelligence or reporting (BI). They can hold relational or nonrelational data. They are typically structured, meaning that the data is extracted, loaded and transformed (ELT) to meet pre-defined schemas before it is stored. This makes executing queries against them much easier than doing so directly against source Continued systems that are operational.
The traditional warehouses on-premises require expensive equipment and software to be hosted. They have a limited storage capacity compared to compute power and must continually discard old data to make space for the newest data. A data warehouse enables users to run historical queries that are impossible on operational systems as they only update with real-time information.
A cloud-based data warehouse, or managed service, is a fully automated and highly efficient solution that’s a good choice for companies that require to analyze vast amounts of data over the course of. It is often a affordable alternative to on-premise data warehouses, since it does not need to use oversized servers and also offers a flexible pricing. You can pay by throughput or hourly use or the amount of resources you are allocated.
