What Is Data warehouse software?
Data warehouse software acts as the central storage hub for a company’s integrated data that is used for analysis and future business decisions. The integrated information within data warehouses comes from all branches of a company, including sales, finance, and marketing, among others. Each of these departments may have its own repository for singular, specific, and relevant information, which are known as data marts. Data warehouses can be built in two ways. The first is a top-down design, which collects all data from the company at a granular level and then allocates the data to specific data marts. The other is a bottom-up approach, where the data marts are created first and then later combined to form a complete data warehouse.
