Data Concurrency

Data concurrency is the phenomenon through that multiple users operate on the similar data concurrently and get response at the same time as without the loss of consistent view of data and without waiting for response from the database.RDBMS permits a huge number of users to execute concurrently a mixture of applications and operate on the similar data concurrently. With this multi-user database access and RDBMS still minimizes data contention and assures data concurrency and consistency.  For  example, Oracle  8’s  data  concurrency  feature  enables  it  to  suit  well  for  both DSS and OLTP  applications. This characteristic could even be viewed as a unique providing from Oracle8.
