Abstract
This paper presents a method for increasing concurrency in shared data bases. A data base is taken to be a collection of entities with structure, such as relations. Concurrency is increased in the sense that several readers and a single writer may access a set of entities. At the same time, either serializability or a slightly weaker form of consistency can be seen by all transactions. Each transaction is assumed to obtain all its resources when it starts. The method also allows for convenient recovery from crashes which do not affect the information on secondary storage.
