| description | The concept of a new universal relation system, called UDH (unified database handler), is given, allowing enquiries of relational databases without references to the underlying database scheme. Also, UDH attempts to decouple data manipulation requests from the database scheme via an additional layer above the database scheme, called semantic object scheme. |
