Hi,
http://www.sap-img.com/abap/difference-between-badi-and-user-exits.htm
Customer Exit : Customer Exits consists of Function Module Exits, Screen Exits, Menu Exits to enhance the standard functionality of SAP Transations. Function Module Exits are implemented using Function Modules (FM). It can be implemented only once. So, it is not reusable. To create an implementation, you have to create a project in CMOD and provide the enhancement name. Inside the FM, there will an include. You have to follow the forward navigation technique & double click it to Create. Then write the code inside that include.
BADI : BADI's use OOPS Concepts. They are implemented using class & interfaces. It is reusuable. Same BADI can be implemented more than once but at any given time only one implementation can be active. BADI Can be Filter Depenedent as well as Filter Independent. SE18 is used for BADI Definitions and SE19 is used to create an implementation for an already existing BADI. For this
implementation, a class will be created which will contain methods which in turn will contain the code.
