I have a WO application that receives, stores and retrieves student study information. More here:
http://www.dyned.com/products/internetrm.shtml
In my model I have a group entity which have sub-groups via one-to- many relationship back to itself. These groups then have classes with students. There is a class entity with many-to-many relationships to the student entity. A student can be in more then one class.
There is a search I need to implement that returns matching groups, classes and students within a givem parent group. I can reach all the objects through relationships so starting with a parent group I can walk through all the sub-groups, classes and students arrays. This is time consuming.
I'm trying to think of a fetch specification that avoids some of the recursive looping I do now.
Any thoughts? Many thanks in advanced. kib"Success is not final, failure is not fatal: it is the courage to continue that counts.”
