| Kurzbeschreibung | This course provides the basics of relational databases from the perspective of the user. We will discover why tables are so incredibly powerful to express relations, learn the SQL query language, and how to make the most of it. The course also covers support for data cubes (analytics). | ||||||||||||||||||||||||||||||||||||
| Lernziel | Do you want to be able to query your own data productively and efficiently in your future semester projects, bachelor's thesis, master thesis, or PhD thesis? Are you looking for something beyond the Python+Pandas hype? This courses teaches you how to do so as well as the dos and don'ts. This lesson is complementary with Big Data for Engineers as they cover different time periods of database history and practices -- you can take them in any order, even though it might be more enjoyable to take this lecture first. After visiting this course, you will be capable to: 1. Explain, in the big picture, how a relational database works and what it can do in your own words. 2. Explain the relational data model (tables, rows, attributes, primary keys, foreign keys), formally and informally, including the relational algebra operators (select, project, rename, all kinds of joins, division, cartesian product, union, intersection, etc). 3. Perform non-trivial reading SQL queries on existing relational databases, as well as insert new data, update and delete existing data. 4. Design new schemas to store data in accordance to the real world's constraints, such as relationship cardinality 5. Explain what bad design is and why it matters. 6. Adapt and improve an existing schema to make it more robust against anomalies, thanks to a very good theoretical knowledge of what is called "normal forms". 7. Understand how indices work (hash indices, B-trees), how they are implemented, and how to use them to make queries faster. 8. Access an existing relational database from a host language such as Java, using bridges such as JDBC. 9. Explain what data independence is all about and didn't age a bit since the 1970s. 10. Explain, in the big picture, how a relational database is physically implemented. 11. Know and deal with the natural syntax for relational data, CSV. 12. Explain the data cube model including slicing and dicing. 13. Store data cubes in a relational database. 14. Map cube queries to SQL. 15. Slice and dice cubes in a UI. And of course, you will think that tables are the most wonderful object in the world. | ||||||||||||||||||||||||||||||||||||

Leistungskontrolle als Semesterkurs | |
| ECTS Kreditpunkte | 4 KP |
| Prüfende | G. Fourny |
| Form | Sessionsprüfung |
| Prüfungssprache | Englisch |
| Repetition | Die Leistungskontrolle wird nur in der Session nach der Lerneinheit angeboten. Die Repetition ist nur nach erneuter Belegung möglich. |
| Prüfungsmodus | schriftlich 180 Minuten |
| Zusatzinformation zum Prüfungsmodus | Working on the exercises is rewarded in the sense of ETH's continuous performance assessment with up to 0.25 bonus points. In principle, it is expected that students solve all exercises. In order to control this, the assignments will be collected in 3 weeks of the semester, announced in advance. Those who successfully solve ast least 2 of these 3 weeks of assignments get 0.25 extra points at the exam. |
| Hilfsmittel schriftlich | General dictionaries are allowed. This includes general English dictionaries (with word definitions) as well as general bilingual dictionaries (English <-> other language). Specialized dictionaries are not allowed. Dictionaries cannot be annotated by hand. |
| Digitale Prüfung | Die Prüfung findet auf Geräten statt, die von der ETH Zürich zur Verfügung gestellt werden. |
| Fernprüfung | Das Ablegen als Fernprüfung ist nicht möglich. |
| Diese Angaben können noch zu Semesterbeginn aktualisiert werden; verbindlich sind die Angaben auf dem Prüfungsplan. | |
