A data warehouse is cloud-based central repository that collects information from varied sources. It lets businesses detect patterns, identify efficiencies, and make better business decisions. It takes time to cross-check the various systems and get accurate information, especially if the data is in flux or massive.

Contrary to a data lake which offers a way to dump all types of raw data (structured and unstructured) for future use cases, a data warehouse keeps a huge collection of well-organized, clean business data in a summary form (fitting into rows and columns) ready to be used in business intelligence. The data is retrieved dataroomtechs.info/ using structured query language (SQL) and the database is specifically designed to meet business requirements.

Digital marketing agencies utilize online data warehouses that access data from various sources and provide their customers with a an overview of their performance. This allows them to make well-informed decisions that have a positive impact on the bottom line, and deliver the best possible results for their customers.

Imagine an online data warehouse as a storage tank, set up to satisfy the needs of a household for clean water (data analysis). Imagine a bicycle maker needs to know more about its customer base. The company could use its data warehouse to gain information about the gender, age, location, and purchasing habits. This information would help the maker of bicycles to develop and market new models of bicycles that are more relevant to its intended audience.
