The banking sector is undergoing a significant transformation as a result of new technical and regulatory requirements which have greatly increased their agility and responsiveness in their core activities. Banks have been digitising their methods of operation which has resulted in the collection of enormous volumes of data due to constant pressure from new players or competitors in the market and the development of mobile devices and technology. Managing data for regulatory requirements as well as gaining useful insights is one of the biggest challenges facing banks today. Any industry must consider data quality and banks need high-quality data to comprehend their market and clientele.
