3 - Tier Architecture is like following :

1. Presentation Layer

2. Business Logic Layer /Data Manager Layer

3. Data Access Layer 

The communication between all these layers need to be done using Business Entities.

1. Presentation Layer is the one where the UI comes into picture. Presentation layer contains pages like .aspx or windows form where data is presented to the user or input is taken from the user.

2. Business Logic Layer is the one where all business logic are implemented. It contains business logic, validations or calculations related with the data, if needed.

3. Data Access Layer is the one which communicates directly to the database. DAL contains methods that helps business layer to connect the data and perform required action, might be returning data or manipulating data


Data from one layer to other needs to be transformed using Entities.

The ASP.NET Wiki was started by Scott Hanselman in February of 2008. The idea is that folks spend a lot of time trolling the blogs, googlinglive-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.

The ASP.NET Wiki articles moved to CodeProject in October 2013 and will live on, loved, protected and updated by the community.
