Object identity set algebra is presented in the paper. The algebra is efficient to express queries to objects and gains support from underlying relational algebra and formal language theories. The algebra lies on top of relational algebra in the structure of layered mathematical models guiding object-oriented database systems. Object identity set algebra is defined precisely to apply mathematical set functions for querying objects in database systems.
