Inhalt:

Based on application scenarios from various organizations, we will discuss aspects of distribution, autonomy and heterogeneity. This helps us to organize the problem space and to compare possible architectures of integrated information systems. Heterogeneity is addressed by schema mappings between and data mappings. We will discuss how to establish such mappings and how to apply them in data transformation. As query processing in federated databases is based on these mappings as well, we will also learn the basics on these systems. Another focus of this course is on the pre-processing and integration of data. Starting with a discussion on information quality, we will look at the spectrum of erroneous data and approaches to data cleansing. State-of-the-art software for information integration will be presented, in particular as part of the exercises.
