Through a lot of the eighties and nineties “database” strictly intended “relational databases.” SQL dominated. 

Then with the increasing reputation of object-oriented programming languages, some assumed the answer to the “impedance mismatch” of object-oriented languages and relational databases was to map objects in the databases. Hence we ended up with “object-oriented databases.” The amusing issue about object databases
