Abstract
Our ability to collect data is rapidly surpassing our ability to store it. As a result, organisations are facing difficult decisions about what data to retain, and in what form, in order to meet their business goals while complying with storage restrictions. This is typically known as data reduction. This talk provides a description of the different aspects of Data Reductions, and attempts to give a more formal definition. It also presents the different directions that the Data Intensive System group @ Utrecht University is considering for this challenge.
