Question

Quizplus · Accepted Answer

Concurrency control techniques allow multiple transactions or processes to access and manipulate the database at the same time, while still maintaining the integrity and consistency of the data. These techniques include locking, timestamp ordering, and optimistic concurrency control. Query processing refers to the methods used to translate and execute user queries on the database. Location transparency refers to the ability of a system to access physical resources (such as files or servers) without needing to know their specific location. Data redundancy refers to the duplication of data within a database or system, which can improve performance and availability but also increase the risk of inconsistencies and errors.
