Class CXS_DATABASE
The logical database managed by the object manager can consist of several physical databases. The (physical) databases are represented by objects of class CXS_DATABASE. With GetDatabases, the object manager provides all databases; with NewDatabase a new CXS_DATABASE object can be created.
The complete documentation of the class can be found here
Class CXS_SEGMENT
The ObjectStore database is divided into segments, which the object manager manages using objects of the class CXS_SEGMENT (see also CLASSIX.INI).
From the object manager, GetSegments gets all segments, QuerySegment gets the segment in which a particular object is stored, and NewSegment creates a new CXS_SEGMENT object.
