Front End Add/Edit/Delete items from list

My dev partner is looking for guidance for some user based front end functionality.

So, in a nutshell, we have a list of properties that a site “member” can input, again from a front end interface. The data is input into a custom table he has created within the DB. That same front end page would simply display a table with the property listings for others.

When the posting member is logged in to the site, we want them to be able to go to the that page and see Edit/Delete on a per item basis and Add would be a single button.

However, we’re not familiar with doing this type of thing in PHP or in WP. We’ve done it in .NET but the method seems to be alluding us for PHP/WP. Are we missing something obvious? Any guidance on best practices for PHP/WP workflow for this type of scenario would be great…even a blunt pointer to the this in the codex would be great!

These “members” will NOT have any access to the WP admin. This is all front end function we’re trying to work through.
