Explain ACID rule of thumb for transactions.

 Posted by deccansoft on 9/18/2010 | Category: C# Interview questions | Views: 2253

A transaction must be:
1.Atomic - it is one unit of work and does not dependent on
previous and following transactions.
2.Consistent - data is either committed or roll back, no
“in-between” case where something has been updated and something hasn’t.
3.Isolated - no transaction sees the intermediate results of the
current transaction).
4.Durable - the values persist if the data had been committed
even if the system crashes right after.
