Overview Research and business is currently moving from centralized databases towards information systems integrating distributed and autonomous data sources. Simultaneously, it is a well acknowledged fact that consideration of information quality - IQ-reasoning is an important issue for large-scale integrated information systems. The paper shows that IQ-reasoning can be the driving force of the current shift from databases to integrated information systems and explores the implications and consequences of the shift. All areas of answering user queries are affected - from user input, to query planning and query optimization, and finally to building the query result. The application of IQ-reasoning brings both challenges, such as new cost models for optimization, and opportunities, such as improved query planning.
