"concurrency" is a valid word in written English and can be used in various contexts.
The term "concurrency" refers to the occurrence of two or more events or processes happening at the same time. It can also describe the ability of a computer system to handle multiple tasks simultaneously. Example: The software update was causing issues with concurrency, as it was unable to process multiple user requests at once, causing the system to crash.
The key to maintaining database correctness is therefore to ensure that only complete transactions are applied to the data and that multiple concurrent transactions are executed (under a concurrency control mechanism) in such a way that a serial order can be defined that would produce the same results.
Parallel concurrency on such a scale is precisely what is needed in these multitasking, multimedia times.
Robin Milner, in full Arthur John Robin Gorell Milner (born Jan . 13 , 1934Yealmpton, Devon, Eng. died March 20 , 2010 Cambridge, Cambridgeshire) English computer scientist and winner of the 1991 A.M. Turing Award, the highest honour in computer science, for his work with automatic theorem provers, the ML computer programming language, and a general theory of concurrency.
Without concurrency control, both may think they have succeeded, while only one booking is actually entered into the database.
A key concept in studying concurrency control and the maintenance of database correctness is the transaction, defined as a sequence of operations on the data that transform the database from one consistent state into another.
Access to a database by multiple simultaneous users requires that the DBMS include a concurrency control mechanism to maintain the consistency of the data in spite of the possibility that a user may interfere with the updates attempted by another user.
"The third thing is this issue of concurrency and making sure where you have really excellent foster carers who want to be the adoptive parents they can do both at the same time.
"The goal was to establish the basic association between different kinds of sexual relationships and concurrency," says Anthony Paik, an assistant professor of sociology, whose results were published in the March issue of Perspectives on Sexual and Reproductive Health.
"Obviously there are different goals from the publisher side, from marketing, but for [the development team], we managed three times the amount of concurrency than we were aiming for.
