Data Bases, Electronic form of data organisation. Since the mid-1980s, relational data bases (based on E. Codd's pioneering 1970 data model) have been used most frequently in Austrian businesses and administration. In research and development, a trend towards object-oriented data bases has been evident since the end of the 1980s.
