object_name - OBJECT_SPACE option

In many cases, a database consists only of the root object space and no object space must be defined.

In some cases the database is, however, build of a number of hierarchical object spaces where each object space may contain a whole universe of object instances. Object spaces are referenced in the defined hierarchy. In order to access a subordinated object space, a path to the object space must be defined in the data source.

The root object space did not get a name, i.e. object space names begin with the first subordinated object space.

Usually, this value is set in the configuration or ini-file in the OBJECT_SPACE option for the data source definition.
