While relational databases exclusively set values in tables in relation to each other, object-related database management
adds further dependencies. Whereas rel
are used,among other things, for time sequences with which, for example, the sales or profit trends of a company are displayed, an Object Relational Database Management System (ORDBMS) can be used to add further complex or multimedia data types
inaddition to the relational data
. In order to enable the management of such multimedia data types, they must be defined and typed in a user-specific manner in object-related database management.
