    1. COI've changed the `entityA.products = orderedSet` to `entityA.setProducts(orderedSet)` and that has fixed the first bottleneck, apparently. The save action still takes ages, though. Looks like hardware limitation, as you said earlier, since in the simulator it only takes 0.2 secs to save the context, while in the iPhone is taking around 4-6 seconds for the very same data.

    2. COI'll try to explain myself better. The fetch is ordered (descently) using a numeric property of entity b. Once the fetch is made, all records are ordered using that field. Hence, I need an ordered relationship to be able to mantain that order. Anyway, I've just tried disabling the order attribute in the relationship, and the performance is more or less the same. I guess I'm doing something terribly wrong which is causing my performance problems. Thanks again!

    3. COThanks Andrew for your response. Answering your questions: 1. Yeah, indexing a relationship probably doesn't make any sense, so I'll remove it. But, I do need the ordered relationship. The order of the B records are important.... Is there any other way to do this using CoreData? 2. No, because I can't assing an ordered set to a bulk setter. I don't know if this is a mistake I'm making, or if it's a known issue. I confess I haven't read further info about this. 3. Yeah, all b records are previously fetched... 4. Does this rule remove also the b records? Or just the relationship info?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
