IUnitOfWork Methods

The IUnitOfWork interface represents the Unit Of Work pattern such that it can be used to query from a database and group together changes that will then be written back to the store as a unit.

Name	Description
HasChanges()	Checks if the unit of work is tracking any new, deleted, or changed entities or relationships that will be sent to the store if IUnitOfWork.SaveChanges is called.
SaveChanges()	Saves all changes made in this unit of work to the underlying store.
