    <p>If I understand correctly you want to use the <code>Employee</code> action methods without being tied to <code>Employee</code> views. </p> <p>I would create a service layer in your application (maybe in a separate project) that deals with Employee logic. Then from your <code>Employee</code> controller and your <code>Timesheets</code> controller you call this <code>EmployeeService</code> service. </p> <p>This way your Business Logic (<code>EmployeeService</code>) is separated from your Presentation logic (<code>Employee</code> and <code>Timesheets</code> controllers and related views). So your controllers can use logic stored in <code>EmployeeService</code> and still utilize their own views for presentation.</p> <p>This in fact becomes a 2-tiered design. If your application is complex enough you might even separate your data access logic into separate layer - effectively making your application 3-tiered. </p> <p>A sample structure might be as follows.</p> <pre><code> Presentation Layer Project (PL) Controllers/ EmployeeController TimesheetsController Views/ Employee/ Timesheets/ ... Business Logic Layer Project (BLL) ViewModels/ Services/ ... Data Access Layer Project (DAL) Models/ Repositories/ ... </code></pre> <p>(Here PL would reference BLL and BLL would reference DAL project).</p> <p>This might give more information: <a href="https://softwareengineering.stackexchange.com/questions/135724/separating-data-access-in-asp-net-mvc">https://softwareengineering.stackexchange.com/questions/135724/separating-data-access-in-asp-net-mvc</a></p>

    1. COExactly how I do it. Controllers are just a thin glue between business logic and UI. At first it seems natural to put business logic in the controllers, but when you start down this path of trying to share business logic, you end up refactoring it out into another layer. Eventually this becomes so common that you just automatically begin every new controller implementation by creating and/or finding reusable service class to handle that backend stuff.

    2. COThis is essentially how I do it, but I'm not sure how that answers my question. With this approach I will still need to have separate views for access from different places? Really all I need to figure out is how to get the "return" links to always get me back to where I came from.

    3. COIf all you want is for your links to get you back to the calling page you'd set that in `Shared\_Layout` view from `ViewBag` variable, for instance, that tracks where you are. Use that to build your links. But `...then return back to where I was called from` - your controller would not do that for you.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
