  Object identifier (OID) is a unique set of numbers that allows Objectivity/DB to locate and manage persistent objects. An OID is 64 bits in length and it is composed of four 16-bit fields in the format of: DB-OC-PG-SL, where

  DB - database identifier (dbid)

  OC - container identifier

  PG - logical page number

  SL - logical slot number on the page

  OID value do not change during the lifetime of an object.

  for the tables u can give GUID data type and define OID

  Object IDs are described here:

  This is how they get encoded into a compact form:
