A data warehouse is a data management system for data reporting, analysis, and storage. It is an enterprise data warehouse and is part of business intelligence. Data from one or more diverse sources is stored in data warehouses, which are central repositories. Data warehouses are analytical tools designed to assist reporting users across multiple departments in making decisions. Data warehouses collect historical business and organizational data so that it can be evaluated and insights can be drawn from it. This helps develop a uniform system of truth for the entire organization.
Due to cloud computing technologies, the cost and difficulty of creating data warehousing for businesses have been dramatically lowered. Previously, enterprises had to invest much in infrastructure. Physical data centers are making way for cloud-based data warehouses and their tools. Many large enterprises still use the old data warehousing method, but it is evident that the cloud is where the data warehouse will function in the future. The pay-per-use cloud-based data warehousing technologies are quick, effective, and highly scalable.
