A data warehouse is an online central repository that collects data from various sources. It allows businesses to identify patterns, find efficiencies and make more informed business decisions. However, it takes time to cross-check different systems and obtain reliable, consistent data — especially when the data is in flux or huge.
A data warehouse is an accumulation of organized, clean business data that can be arranged into rows and columns for business intelligence. Data is retrieved through structured query language (SQL) and the design of the database is usually purpose-driven, with a focus on meeting specific business requirements.
Digital marketing agencies draw data from multiple sources to provide their customers with a the complete picture of their performance. This helps them to make informed choices that positively impact the performance of their business and provide the most effective results for their clients.
Imagine an online data warehouse as a water storage tank that is set up to meet the needs of a family for clean water (data analysis). Imagine a bicycle manufacturer wants to learn more about its customer base. The company could use its database to gather information about age, gender and the location. It can also find out more about the purchasing habits of customers. This data will allow the bike manufacturer develop and introduce new models of bicycles which are more relevant to its intended customers.
