Implementing Model-level caching

Question

I was posting some comments in a related question about MVC caching and some questions about actual implementation came up. How does one implement a Model-level cache that works

Answer 1

You should have a seperate Model which does the SQL interfacing directly, eg. for a Customers table: $CustomerModel->GetCustomers($parameter); et cetera. Then, in those models, you can implement caching transparently without having to edit any of your existing MVCs.
