Techopedia Explains Oracle Database (Oracle DB)
Databases are used to provide structure and organization to data stored electronically in a computer system. Before they were adopted, early computers stored data in flat file structures where information in each file was separated by commas (CSV files). However, as the number of fields and rows that defined the characteristics and structure of each piece of data continued increasing, it was only a matter of time before this approach would become unmanageable.
