Can you explain transactions in WCF? (Views: 3469)


5        0

We have 6 type so transactions are there The data affected by a transaction is called volatile.
Chaos: - pending changes from more highly isolated transactions cannot be overridden.
ReadCommitted: - Volatile data can be modified but it cannot be read during the transaction.
ReadUncommitted: - Volatile data can be read as well as modified during the transaction.
RepeatableRead: - Volatile data can be read but not modified during the transaction and
also new data can be added.
Serializable: - Volatile data can be only read. But no modifications and adding of new
data is allowed.
Snapshot: - Volatile data can be read. But before modifying the data it verifies if any
other transaction had changed data. If yes then it raises error.
By default, the System.Transactions infrastructure creates Serializable transactions.
