An update protocol for an OODB with integrity

Some of the implications of providing referential and general integrity are outlined. Different query execution strategies required to support such integrity are described. SIM (semantic information manager) is an object-based database management system that implements some of these strategies. The strategy implementation is described along with some optimizations that have been introduced into the system. Some unresolved issues are described with respect to integrity enforcement in object-oriented databases that support high-level languages.<
