There are no mid-terms. The exam of Decision Support Systems (801AA, 12 ECTS) consists of a written part and an oral part on the topics of the first module (50% of the final grade), and a lab project with discussion on the topics of the second module (50% of the final grade). See Module I: Decision Support Databases for the theory part. The project of Module II can be discussed only after passing Module I and not later than one year since then.

PROJECT

A project consists of a set of assignments corresponding to a BI process: data integration, construction of an OLAP cube, querying of the OPLAP cube, and reporting.

The project has to be performed by a team of 3 students.

Each part of the project must be documented with a brief pdf report (no more than 5 pages) describing your solution.

Final Project version to be delivered within 27/12/2024

• Dataset: Link
• First part of the project consists in the assignments described here: Project Part 1 (updated 26/11/2024). Deadline: 05/12/2024
• Second part of the project consists in the assignments described here: Project Part 2 (updated 28/11/2024). Deadline: 27/12/2024

Project to be delivered during the exam sessions Students who did not deliver the above project by 27/12/2024 need to ask by email a new project to the teachers. The project that will be assigned will require about 2 weeks of work. After the delivery, the project will be discussed during the oral exam. For those students, the oral exams will also cover some practical parts that could not be included in the project. Please write to all teachers!

Registration to the written exam is mandatory (pay attention at the deadline for registering!): register here

Please indicate in the notes “Only Lab” for doing only the discussion of the lab project; “Only DSD” for doing only the written+oral part of the DSD module; or “DSD+Lab” for doing both.

Important: the date of the discussion of the lab project will be communicated to you. The dates at the registration website regard only the written part of the DSD module.
