In an object--oriented database the objects are encapsulated, i.e., objects are only accessible by methods defined in the database system. Our definition of object-oriented serializability takes...
Position Statement to the Panel
Erich J. Neuhold, Thomas C. Rakow
Today's database systems control the execution of concurrent transactions by ensuring the serializability condition. Serializability is easy to understand and allows to reason
