Client/server database system

A database client for use in a database system including a database server including a storage section for storing information regarding at least one record and a holding section for storing a link to relate records to each other, said database client comprising:

• a link generating information table,
• wherein said link generating information table receives as an input thereto an attribute value of an arbitrary record and holds at least one link generating information item to generate a link relating records to each other;
• and
• a link controller for reading a link generating information item registered to said link generating information table, generating at least one link between records, and registering the at least one link to the database server.

A database server for use in a database system including the database server and a database client, said database server comprising:

• a first storage section for storing information regarding a plurality of records;
• a second storage section for storing a link to relate records to each other;
• a section for receiving and for storing registration of a link between a plurality of records, the link being generated by the database client according to a link generating information item stored in a link generating information table held by the database client to generate a link between records,
• wherein said link generating information table receives as an input thereto an attribute value of an arbitrary record and holds at least one link generating information item to generate a link between records,
• wherein the database client comprises:
• a link controller for reading a link generating information item registered to the link generating information table, generating at least one link between records, and registering the at least one link to the database server, and
• wherein the database server receives registration of the at least one link generated by the database client and stores the at least one link in the holding section.

A program product for implementing on a computer a database client for use in a database system including the database client and a database server having a storage section for storing information regarding at least one record and a holding section for storing a link to relate records to each other, comprising:

• a code for receiving as an input thereto an attribute value of an arbitrary record and making a link generating information table disposed in a storage of the computer for holding at least one link generating information item to generate a link relating records to each other;
• a code for reading a link generating information item from the link generating information table registered to the storage;
• a code for generating at least one link between records;
• a code for registering the link to the database server;
• wherein the database client comprises:
• a link controller for reading a link generating information item registered to the link generating information table, generating at least one link between records, and registering the at least one link to the database server, and
• wherein the database server receives registration of the at least one link generated by the database client and stores the at least one link in the holding section;
• and
• a storage media for storing the codes.
