The tutorial extends and deepens the foundational concepts and challenges discussed in the lecture by examining, applying, and critically assessing various technologies and standards for integrating business information systems. In the first block, the tutorial starts with a consideration of XML and related technologies (e.g., DTD, XML Schema, Java and XML APIs, XPath, XQuery, XSLT, and XML application standards). This allows for a critical assessment of the integration of business information systems based on document exchange formats. In the second block, the tutorial covers integration through database technologies. This includes a treatment of relational databases, object persistence, and data warehouses. The part on object persistence is concerned with object persistence by means of RDBMS, the use of object-relational persistence frameworks (including JPA and corresponding example frameworks), as well as dedicated object-oriented databases. The part on data warehouses discusses (1) practical motivations, challenges, and procedures of establishing data warehouses, (2) prototypical architectures, components, and processes related to data warehouse systems, (3) data models used in the context of data warehouse systems (in particular, multi-dimensional data models), as well as (4) the practical implementation and assessment of an example data warehouse system. The considered end user components include static reporting, on-line analytical reporting (OLAP), and data mining tools. Finally, in the third block, the tutorial concludes with a discussion of decision support and expert systems (knowledge-based systems) and an application of corresponding example tools.
