X/Open XA

Index X/Open XA

In computing, the XA standard is a specification by The Open Group for distributed transaction processing (DTP). [1]

12 relations: ACID, Atomicity (database systems), Data store, Database transaction, Distributed transaction, DRDA, Front and back ends, Standardization, The Open Group, Transaction processing, Tuxedo (software), Two-phase commit protocol.


In computer science, ACID (Atomicity, Consistency, Isolation, Durability) is a set of properties of database transactions intended to guarantee validity even in the event of errors, power failures, etc.

Atomicity (database systems)

In database systems, atomicity (or atomicness; from Greek atomos, undividable) is one of the ACID (Atomicity, Consistency, Isolation, Durability) transaction properties.

Data store

A data store is a repository for persistently storing and managing collections of data which include not just repositories like databases, but also simpler store types such as simple files, emails etc.

Database transaction

A transaction symbolizes a unit of work performed within a database management system (or similar system) against a database, and treated in a coherent and reliable way independent of other transactions.

Distributed transaction

A distributed transaction is a database transaction in which two or more network hosts are involved.

Front and back ends

In software engineering, the terms front end and back end refer to the separation of concerns between the presentation layer (front end), and the data access layer (back end) of a piece of software, or the physical infrastructure or hardware.

Standardization or standardisation is the process of implementing and developing technical standards based on the consensus of different parties that include firms, users, interest groups, standards organizations and governments Standardization can help to maximize compatibility, interoperability, safety, repeatability, or quality.

The Open Group

The Open Group is an industry consortium that seeks to "enable the achievement of business objectives" by developing "open, vendor-neutral technology standards and certifications".

Transaction processing

Transaction processing is information processing in computer science that is divided into individual, indivisible operations called transactions.

Tuxedo (software)

Tuxedo (Transactions for Unix, Extended for Distributed Operations) is a middleware platform used to manage distributed transaction processing in distributed computing environments.

Two-phase commit protocol

In transaction processing, databases, and computer networking, the two-phase commit protocol (2PC) is a type of atomic commitment protocol (ACP).
