optimistische Parallelität (A method of managing concurrency by using a cached object's version information. Because every update to an object changes its version number, using version information prevents the update from overwriting someone else's changes); optimistische Nebenläufigkeit (A type of locking in which the data page or row containing one or more records (rows) -- (including the data being edited) -- is unavailable to other users only while the data is being updated, but is available between the Edit and Update operations) |
