The concurrency control of a DBMS is the mechanism that ensures the correctness and consistency of the data when multiple users and applications access and modify the database simultaneously.

The three-level database management system (DBMS) architecture splits databases into three distinct layers: An internal DBMS schema for low-level storage tasks. A conceptual DBMS schema for logical ...

Concurrent execution of transactions in database management systems (DBMSs) may lead to contention for access to data, which in a multilevel secure DBMS (MLS/DBMS) may lead to insecurity. Security ...

Concurrency control algorithm for shared disk cloud DBMS Abstract: Using shared disk architecture for relational cloud DBMSs enhances their performance and throughput and increases the scalability. In ...

We decompose the problem of concurrency control into the sub-problems of read-write and write-write synchronization. We present a series of timestamp-based algorithms (called synchronization ...
