Enterprise Library - Caching

[Mythran]

Simple question, hopefully simple answer :)

In a multi-tier application, when should I cache my data? Business Logic
Layer or Data Access Layer?

Thanks,
Mythran

Hello
I think you should cache in the business logic layer. Database calls are
always expensive calls. It also depends on the application. If the
application uses any legacy systems like mainframe, I suggest using business
logic layer.
If you give me more application details, I think we can still debate the
pros and cons of database and business layers.
thanks
