Serializable and Repeatable Read isolation levels offer protections so your users won’t see weird or incorrect data – but there are tradeoffs for those protections.

In this course, you’ll dig into:

• How to tell if your existing applications are using these types of isolation levels
• When you might want to raise your isolation level in SQL Server
• The tradeoffs you make if you choose serializable or repeatable read with disk based tables.

Note: In this course, we focus on disk-based tables. In-Memory OLTP (“Hekaton”) works differently — it’s not lock-based! Learn about In-Memory OLTP and Isolation Levels here.
