SQL Server Supported Transaction Models -



SQL Server Supported Transaction Models -

i have question sql server transaction models. much know, have 5 models or modes of transaction in database(flat, distributed, nested, multilevel , chained). wanna know 1 of them exist in sql server (any version) or in improve way, sql have kind of transaction model , back upwards them? surfed web couldnt find related question. please help me

a quick search suggests next article exploring sql server's distributed transactions, should give starting point actual question.

update

from technet's documentation on transactions:

explicit transactions explicitly start transaction. autocommit transactions each individual transact-sql statement committed when completes. implicit transactions the next statement automatically starts new transaction. when transaction completed, next transact-sql statement starts new transaction.

so while terminology little different, flat, distributed, nested , chained supported. multilevel may be, i'm not familiar plenty semantics say.

you may interested in isolation levels in database engine, in sentiment can have much larger impact on application's characteristics (where distributed tranactions arguably more of scheme level concern?)
