1.7. CHAPTER SUMMARY

  • Companies are desperate for strategic information to counter fiercer competition, extend market share, and improve profitability.

  • In spite of tons of data accumulated by enterprises over the past decades, every enterprise is caught in the middle of an information crisis. Information needed for strategic decision making is not readily available.

  • All the past attempts by IT to provide strategic information have been failures. This was mainly because IT has been trying to provide strategic information from operational systems.

  • Informational systems are different from the traditional operational systems. Operational systems are not designed for strategic information.

  • We need a new type of computing environment to provide strategic information. The data warehouse promises to be this new computing environment.

  • Data warehousing is the viable solution. There is a compelling need for data warehousing for every enterprise.
