Question
What do you mean by optimistic locking?
Answers
Database tables are open for read/write over entire network for all users/sessions. It results in increased throughput but results in the loss of updates during parallel access.
For example:-

User x reads a record
User y reads the same record
User x updates that record
User y updates the same record

User y has now over-written the changes that User x made.   Your Comment
