Hi Ganga,

These aren't exactly examples, but this is basically a simplified rule of thumb for business rules.

Value	Use Case
display	Use to provide client scripts access to server-side objects. For more information, see Scripting with Display Business Rules.
before	Use to update information on the current object. For example, a business rule containing current.state=3; would set the State field on the current record to the state with a Value of 3.
after	Use to update information on related objects that need to be displayed immediately, such as GlideRecord queries.
async	Use to update information on related objects that do not need to be displayed immediately, such as calculating metrics and SLAs.
