Access Repository through Service or directly?

Question

Hello,

is it a good coding standard to allow ASP.NET MVC controller actions to access a repository directly (even though a service layer is present for the heavy lifting, e.g. LoginService.Authorize() ) to retrieve, add, or update data? Or should everything go through the service, and from there to the repository?

Answer 1

It's better to go through the service layer (depending on how you've implemented it though), because that's the point of it - to be a single access point, thus any business-specific things you do there, are represented and implemented across all callers.

Answer 2

For smaller applications/webs, i tend not to use service layer, because it just maps Repositories methods 1:1, and I loose KISS. But in the end, it depends on business model; repository abstracts db access, and services encapsulates logic.

Answer 3

It really depends on the complexity. If you're dealing with any transcation scoping, I'd definitely decouple that away from the controller into your service layer.
