What is the meaning of "Unit of Work" concept in NHibernate and other ORMs?
984
The unit of work class coordinates the work of multiple repositories by creating a single database context class shared by all of them.
A unit of work is a recoverable sequence of operations within an application process. It is used by the database manager to ensure that a database is in a consistent state. Any reading from or writing to the database is done within a unit of work.
The Unit of Work pattern is used to aggregate multiple operations into a single transaction. With this we ensure that either all operations succeed or fail as a single unit. Note that you can use the Repository pattern without using the Unit of Work pattern.
The Unit of Work pattern is used to group one or more operations (usually database CRUD operations) into a single transaction or “unit of work” so that all operations either pass or fail as one unit.
It is explained very well in this blog post.
"A Unit of Work keeps track of everything you do during a business transaction that can affect the database. When you're done, it figures out everything that needs to be done to alter the database as a result of your work."
