I am implementing customer specific code and currently following simple approach like if (cusomterId == 23) do it. I want to separate out all the customer related code in separate place. But I have following problems.

In code is in 1. Stored procs 2. Plain old classes. 3. Controllers 4. Views

I came up with two solutions.

First is to create table CustomerFunctionlity with columns CustomerId, FunctionalityName, method/Proc, inputs/outputs

With this table I can simply check if exists, execute given function.

Another way is creating a factory which returns customer related object for an interface.

I am writting small end to end customer specific functionalities. How can I write maintenable code.

Thanks
