Glad that if you are glad.

for the sake of conclusion, I assume, your definition of ETA is “price for lower” collection, it is a master collection that contributes price to lower collection, in your case maybe, it contributes period of time, such minutes.

waypoints is lower collection, in my terms.

journey is middle collection.

Collections cascading and copy

Hi All, This is a series of tutorial about relational collections that are cascaded, meaning it is maintained in 1-to-many relationship. There are 5 levels of collection, from top to bottom: highest such as projects higher such as activities inside project middle such as purchase orders inside activity lower such as order items inside purchase order lowest such as accessories inside order item But, we will begin with lower first and later, we will use lowest, then going to middle, higher …

Whenever I can, I try to use 1-to-m relationship, because they are easier to manipulate, using generated records that are a copy of master collection that also related in 1-to-m.

For m-to-m, I usually use for description or delegation, moving from 1-to-m relationship to another 1-to-m, it is just for bridge, not for accumulation/summary.

Terms are always different, but levels and 1-to-m are forever the same.
