Historical Roots
DB2 is a relational database management system produced by IBM that IBM refers to as a “data server.” What is a relational database? A relational database is a set of files that has been analyzed for all of the relationships between fields. The related fields are pulled out of the original files in order to minimize redundancy in the data being stored. For example, instead of storing the information that TN is the state Tennessee in every record, that information is pulled out of the original file and stored only once in a state code file.
