The purpose of this paper is to raise awareness and identify a number of challenges regarding the issue of data warehouse interoperation in Web-based collaborative environments. Adopting system and information quality as success variables, we argue that existing works fell short of addressing complex issues that relate to their refreshment and extent far beyond view maintenance solutions within single warehouses. Considering a solution that approaches warehouse refreshment as a business process in a federation of data warehouses, we define a special kind of materialized view that emanates from such an environment, provide a roadmap for implementing the appropriate warehousing architecture, and give some preliminary empirical results.
