The Book on the open HPI Course: Hasso Plattner Explains In-Memory Databases
The almost 300 page book on the course explains in detail “the inner mechanics of in-memory databases,” as stated in the subtitle. Plattner, who as a professor at HPI leads the research area, “Enterprise Platform and Integration Concepts,” has written the work primarily with students in mind. However, it is also aimed at software developers, IT experts, analysts and business decision-makers. The material is divided for readers into 34 units. 110 illustrations, simple explanations and more than 100 self-tests facilitate comprehension of the contents. Special attention has also been paid to supplying extensive answers to the self-study questions. The detailed answers, which were not yet available in the online course, provide readers with a deeper understanding of the concepts presented and round off the relevant sections didactically.
The thematic focuses on the inner workings of column-oriented in-memory databases. Among the areas addressed are: the physical storage of data and access to it, basic database processes, compression mechanisms and efficient algorithms for the parallel processing of requests. In addition, the impact on future company applications and their development are discussed. The reader is given an understanding of the radical differences and advantages of the new technology as compared to conventional line-oriented and disk-based databases.
