What is a data mart, and how does it differ from a data warehouse in terms of analytical purposes?
A data mart is a smaller, more focused repository of data, tailored for a specific business function or department. Unlike a data warehouse, which integrates data from across an organization, a data mart simplifies access to data by limiting it to relevant subsets for faster, targeted analysis.For example, A marketing data mart may focus only on marketing campaign data, while a data warehouse would contain all company data across departments like sales, HR, and finance.
