Modern Interactive Data Analysis (IDA) platforms, such as Kibana, Splunk, and Tableau, are
gradually replacing traditional OLAP/SQL tools, as they allow for easy-to-use data …

While OLAP has a key role in supporting effective exploration of multidimensional cubes, the
huge number of aggregations and selections that can be operated on data may make the …

Database access logs are the starting point for many forms of database administration, from
database performance tuning, to security auditing, to benchmark design, and many more …

In this paper, we discuss methods to assess the interestingness of a query in an
environment of data cubes. We assume a hierarchical multidimensional database, storing …

Recently, the learning-based models are shown to outperform the conventional methods for
many database tasks such as cardinality estimation, join order selection and performance …

This work studies the problem of constructing a representative workload from a given input
analytical query workload where the former serves as an approximation with guarantees of …

We consider the problem of generating SQL notebooks of comparison queries for
Exploratory Data Analysis (EDA). A comparison query allows to find insights in a dataset by …

The query optimizer is responsible for identifying the most efficient Query Execution Plans
