Comparison of Read Committed and Serializable Isolation (321)

Oracle gives the application developer a choice of two transaction isolation levels with
different characteristics. Both the read committed and serializable isolation levels
provide a high degree of consistency and concurrency. Both levels provide the
contention-reducing benefits of Oracle’s read consistency multiversion concurrency
control model and exclusive row-level locking implementation and are designed for
real-world application deployment.
