Explain Concurrency Control With Lock Based Protocols. Lock based protocols help to eliminate the concurrency problem in dbms for simultaneous transactions by locking or isolating a particular transaction to a single user. (i) enforce isolation among transactions. To know more about the concept of concurrency, read here:. Data items can be locked in two modes : A lock is a mechanism to control concurrent access to a data item. Data items can be locked in two modes : We have concurrency control protocols to ensure atomicity, isolation, and serializability of concurrent transactions. In this type of protocol, any transaction cannot read or write data until it acquires an appropriate lock on it. There are two types of lock: Concurrency control is provided in a database to: In a shared lock, the data item can only read by the transaction. A lock is a mechanism to control concurrent access to a data item.
