0	DAL - Data access layer - It does all the functionalities related to connecting database, fetching records, executing scripts, etc.. Tomorrow in case, if you want to change the database from sql to oracle or mysql, u need to do changes only in this layer. BL - Business Layer - It has all the business related logic, validation and rules. DTO - Data transfer object. It transfers the data throught out the application (from DAL to BL to PL) Thanks, R.Vasanth MCTS(SQL Server & BI) http://bigdatatech.blogspot.com Rajesh081725, if this helps please login to Mark As Answer. \| Alert Moderator
