Objects are always serialized/deserialized into a memory buffer (see ODB.Storage). Depending on the storage strategy the serialization buffer will be transferred to or from the target media.
Connection with the storage media
The media specific implementation defined the order in which objects are retrieved from the object table in ODB.Persistent.
The ODB.Storage.File package retrieves all objects from the object table in sequence and writes the object names into a so called index file and each object is written an individual file.
The individual objects are stored in single files.
