The maintenance of materialized aggregate join views is a well-studied problem. However,
to date the published literature has largely ignored the issue of concurrency control. Clearly …

Weighted voting is used as the basis for a replication technique for directories. This
technique affords arbitrarily high data availability as well as high concurrency. Efficient …

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 …

There is growing evidence that for a wide variety of database workloads and system
configurations, locking-based concurrency control outperforms other types of concurrency …

A database schema should be able to evolve to reflect changes to the universe it represents.
In existing systems, user transactions get blocked during complex schema transformations …

Deadlock is one of the most serious problems in multitasking concurrent programming
systems. The deadlock problem becomes further complicated when the underlying system is …

Four major problems that complicate read and write accesses to instances in object-oriented
databases are discussed. The four problems are: difficulty in providing ad hoc commutativity …

Database Concurrency Control: Methods, Performance and Analysis is a review of
developments in concurrency control methods for centralized database systems, with a …

We define a series of locking protocols for database systems that all have three main
features: freedom from deadlock, multiple granularity, and support for general collections of …
