I am currently investigating the possibilities of different CMSs for a company-site.
Done quite a few projects in classical ASP, ASP.NET, Joomla etc..

I would like to use Umbraco 5 for the first time.

For that project we have a SQL-Table with Job-Opportunities: 
like: JobName, Department, Description, etc..
These should be listed on a page. In ASP.NET I would use something like a Repeater, etc.. with PageSize option and automatic paging.
In the Backend (Backoffice in Umbraco, I assume) there has to be an Insert/Edit/Delete  Page with the corresponding input boxes, which are maintained by the company employees, not by web-developers.

Which route should I look at? I am completely stuck, is there an example anywhere?
Can I use my own data-tables, or could/should I use the Umbraco content tables for this?

Thank you,
Reinhard
