Ming is an API for working with data in MongoDB. It was designed to allow rapid construction of MongoDB-based apps in Drupal, where Field integration is not required.
Ming is a wrapper around the PHP Mongo classes, which adds some additional capabilities and behaviours. In addition to what raw Mongo support provides, Ming has the following features:
Preconfigure and connect to multiple persistent connections, from multiple Mongo database sources, using hooks, site variables, at runtime, or from the Mongodb module
Simple wrappers around common Mongo tasks (Insert, Upsert, Delete, Find), including some common variants
Shortcuts for accessing objects by MongoID, without the need to instantiate MongoID classes
A scaffold class (ming\Ming\Item) for building, saving and working with MongoDB data
Ming does not require the Mongodb module to be installed, but will work with it.
