When working with the database entities in SQL Server Data Tools, you are not working on the real database. Instead you are working on an in-memory model of the database. All pending changes are buffered in this working copy. The name for this feature is the Power Buffer. This tutorial explores how the Power Buffer optimizes pending changes and batches them all for a single update to the real database.
