Link to Activity in Same Table (A2K, SP3)
I'm sure this has been covered before, but I'm not even sure how to search for it.
I'm putting together a database to track activities. These activities will have a start date and a duration, as well as various other information. In many instances, there will be activities dependent on other activities already in the table. I'd like to be able to create a report that flags what activities are dependent on others, and possibly even move their start dates when the parent activity end date moves. I can envision doing this using two separate tables, but this approach seems wasteful. <img src=/S/brickwall.gif border=0 alt=brickwall width=25 height=15>
Thanks in advance.

That approach may seem wasteful, but it is proper relational design. Anything else becomes a maintenance nightmare.
