A couple of things to consider:
1. from my experience large views (many columns) are slower than a parent-child relationship.
2. Depending on what you do, you may have trouble updating data from a view.
3. You can have a child relationship with only one record. Create a separate base table block on the same canvas with a link to the parent block, it'll look the same to a user. Let oracle do the work. 4. You can also create a separate block on the same canvas and manually control the data by programatically configuring the default where clause defined in the block.
5. I always suggest using base table items instead of created text items because you can program the data edits directly in the database instead of needing reams of code.

Hope that helps,
Lewis
