(1) database access efficiency and Computer real-time processing speed are improved.Traditional table locking means, are often being opened
It needs to carry out using the query statement (the SELECT FOR UPDATE statement in such as SQL statement) with exclusive lock when beginning
Inquiry, which needs to fall into a long wait in the state that target data has had exclusive lock, exclusive until target data
Lock is released and can just trade, therefore when transaction flow access target data are more and exchange hour is long,
It is easy to cause transaction to need to wait lock and cause elongated the time required to transaction.And by using this method, greatly shorten this
The inquiry application lock table time in the case of kind is reduced time control with itself required time of individually trading because waiting
And the system resource occupied.
