Below is the code for BAL (Your can overwrite your default written code for the class file by pasting this code).

Download source code for 3-Tier Architecture in ASP. Seperation - the functionality is seperated from the data access and presentation so that it is more maintainable 2. As we don't have any business logic here so simply instantiate the Person DAL3 class of DAL and call methods. Now we have all set to go, now just run your project and try inserting records. Now, create a class named Person BAL3 into App_Code folder by right clicking it and write respective methods for calling Insert, Delete, Update and Load methods of Data Access Layer class file (Person DAL3) (In my case I have a 3-Tier folder inside App_Code folder, you can directly add inside App_Code or you can create a separate project for BAL and add reference of this project into your Presentation Layer). In the above method, I am instantiating Person BAL3 and calling the Update method by p[assing required parameters.In real scenario, you should create separate projects for BAL, DAL (as Class Library) and UI (as Web project) and reference your BAL into UI.
