Implementing Optimistic Concurrency:
Step 3-Creating a Business Logic Layer for the Optimistic Concurrency-Enabled DAL
This step of the VIDEO TUTORIAL will demonstrate on how to create a business logic layer that will become a wrap around the newly created data access layer in the previous step that supports the optimistic concurrency features. This is achieved by adding a new class file to the App_Code’s BLL folder titled as ProdutsOptimisticConcurrencyBLL.cs. A Delete and Update overload methods that take the optimistic concurrency features into consideration also added to the newly created ProductsOptimisticConcurrency table adapter. In addition, two patterns known as DBDirect as well as DB Batch Patterns are examined in deleting and updating product tables in the database.
