This chapter discusses the history of data from ancient times to modern databases. It explains how humankind has been interested in data for at least 12,000 years, initially using simple methods like pebbles to track livestock. Over time, data storage evolved through clay tokens, double-entry bookkeeping in the 14th century, punched cards in the 19th century, and the development of mainframe computers in the 1950s using magnetic tape and disks. The chapter describes how data became a crucial corporate resource, driving the need for database management systems to securely store and provide efficient access to massive amounts of company data in order to gain a competitive advantage.
