Question

Apologies for the shopping list, but I’ve played with a few ORM-type libraries, and most are good, but none have done everything 🙂 On my next project, am hoping to find one that can do a few more things out of the box. Have you got any good suggestions?

This is what I am looking for:

1. Easily select deeply nested data.

   for example, PHP Yii’s CActiveRecord can do something like this: Contact::model()->with(‘phone_numbers’, ‘addresses’, ‘createdBy.user.company’)->findAll();

2. Easily create/return deeply nested JSON from the database or ORM

3. Easily load deeply nested JSON data, validate it, and save it to the database correctly

4. Supports optimistic concurrency control

5. Handles multi-tenant systems gracefully

Answer 1

Easily select deeply nested data / Easily create/return deeply nested
JSON from the database or ORM

Yet to find one…you need a generic way to convert to/from objects, arrays, json in and out, recursively

Easily load deeply nested JSON data, validate it, and save it to the

Supports optimistic concurrency control

Doctrine or brew your own w a “version” counter on a record

Handles multi-tenant systems gracefully
