Learning outcomes:
After successfully completing this module, students will be capable of handling large amounts of structured and unstructured data. They will know the basic structures of a (relational) database system and be familiar with implementation techniques (e. g. index structures and blocking mechanisms), as well as their benefits (e. g. query acceleration and transaction isolation). Students will be able to differentiate between transaction-oriented (OLTP) and analytical (OLAP) application scenarios. They will know the basic terms of so-called data warehouses and can express analytical information requirements in a suitable query language (e. g. SQL and MDX). Students will be familiar with basic information retrieval models (e. g. vector space model) and can apply them to sample data, in order to master unstructured data (e. g. text documents). They will be familiar with quality criteria (e. g. precision and yield) and can calculate them for the determined results. Students will be familiar with data mining methods, such as the analysis of shopping carts, as a means of gaining knowledge from data. Students will be capable of systematically determining the parameters of such procedures and critically assessing the results. Students will be familiar with the platforms available for distributed data processing, (e. g. MapReduce and Spark). They will be able to select a suitable platform for a given analytical task and implement the task using this platform.
