  • [16-11-2021]: Instructions for the SSAS project in the Lecture of today: to avoid conflicts in deployment/process follow this steps once the solution is opened: (1) rename the project as <your account>_foodmart (2) from project properties select 'Deployment', then rename the database as <your account>_foodmart; (3) click on the button “show all files” just above “Solution explorer” right click on “view code” on the .database file that is visualized, and then change the ID from ruggieri_foodmart into <your account>_foodmart, and finally save the file; (4) change the credentials of connection to database on SQL Server. As an alternative solution you mayimport the project from the SSAS server and rename it as <your account>_foodmart (step 4 is still necessary).

A project consists in a set of assignements corresponding to a BI process: data integration, construction of an OLAP cube, qurying of a OPLAP cube and reporting.

The project has to be performed by a team of 2 students (at most 3 after asking authorization for that to the teachers).

Project to be delivered within 31 December 2021

Project to be delivered during the exam sessions Students who did not deliver the above project within 31 December 2021 need to ask by email a new project to the teachers. The project that will be assigned will require about 2 weeks of work and after the delivery it 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.
