Companies should update their data as often as necessary to ensure the accuracy of their business decisions. This could mean daily, weekly, or monthly updates depending on the type of data and how it is used. For example, if a company relies heavily on customer data for marketing campaigns, they may need to update that data more frequently than other types of data. It’s also important to consider the cost associated with updating data too often; companies should weigh the benefits of frequent updates against the costs of doing so.
