Abstract

While the size of data stores has grown exponentially and the complexity of data has increased significantly over recent years, the standard database operators we work with remain relatively unchanged. We are developing new relational database operators that allow users to more naturally ask and answer complex questions regarding large data sets for tasks such as data mining and big data analysis. We will discuss several operator variants and show how they can help us answer different types of questions that are difficult to answer with the currently available database operators.
