Virtual Organizations (VO) are on the rise fueled by a more global base for commerce, technology development to support VOs and a more global demand for products, and virtuality can fundamentally transform the ways in which organizations operate. In order to operate successfully a VO must develop a knowledge infrastructure which allows for seamless flow of information between geographically distributed people, processes and repositories. To support this a virtual data warehouse needs an architectural design with a logically common meta-data, common semantics and common business rules. While data warehouses have been designed to support the traditional organization the VO’s high level of uncertainty and lack of centralized control make the construction of a data warehouse to support a VO more challenging. This paper presents two possible scenarios for accomplishing this along with advantages and disadvantages of both and measures of success.
