The need to warehouse information advanced as companies began relying on pc techniques to create, file, and retrieve important business paperwork. The idea of data warehousing was introduced in 1988 by IBM researchers Barry Devlin and Paul Murphy. An entity-relationship model is the basic software when designing a relational database.
