Data mining is an interdisciplinary subfield of computer science used to discover patterns in complex datasets. The field has been widely studied since the 70’s since it can produce useful insights that can help to better understand underlying relationships and trends in data sets.

The relational model was proposed in a paper published in 1970 by Edgar Codd, a computer scientist working at IBM. In previous years, some storage systems had already emerged, but the relational model was first proposed with a strong theoretical basis.
