Because spreadsheets are easy to work with, many businesses rely on them to take the place of a data mart or data warehouse. Instead of providing a consistent view of the entire company’s data, however, spreadsheets have unique views of limited amounts of data. It is up to the spreadsheet creator to decide what metrics are important, what data needs to be collected, how the data is formatted and what level of granularity is required.
