Title: Serializability in object-oriented database systems
Abstract: In an object-oriented database the objects are encapsulated, that is, objects are only accessible by methods defined in the database system. The definition of object-oriented serializability takes advantage of the semantics and of the nesting of the methods. Therefore, a lower rate of conflicting accesses than with the conventional definition of serializability is achieved. Transactions of an object-oriented database are defined as open-nested transactions. Depending on the semantics of operations, actions can be serialized independently of the calling transactions. The techniques already used in multilayer transaction systems are extended to object-oriented systems. Object-oriented serializability includes multilayer serializability but allows a nonlayered, more general structure of the database system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
