The aim of this lecture is to present how popular user-centric techniques, namely personalisation and recommendation, can be adapted to an OLAP context. The presentation begins with an overview of query personalisation and query recommendation in relational databases. Then it introduces the approaches proposed for personalising OLAP queries with user preferences, and the approaches proposed for recommending OLAP queries. All the approaches are characterized in terms of formulation effort, prescriptiveness, proactiveness, expressiveness, and in terms of the data leveraged: the current state of the database, its history, or external information.
