Quizplus · Accepted Answer

An Operational Data Store (ODS) is a database that is used for transaction processing systems and uses data warehouse concepts to provide clean data. The ODS is used for short-term decisions involving mission-critical applications rather than for the medium- and long-term decisions associated with the regular data warehouse. An analytical database is a database that is optimized for data warehousing and data mining, while a data backup system is used to create and maintain copies of data to protect against data loss. A data mart is a subset of an organization's data that is specifically designed to serve a particular business unit or function.
