- * @fileOverview The **Db** class is a class that represents a MongoDB Database.
- *
- * @example
- * var MongoClient = require('mongodb').MongoClient,
- * test = require('assert');
- * // Connection url
- * var url = 'mongodb://localhost:27017/test';
- * // Connect using MongoClient
- * MongoClient.connect(url, function(err, db) {
- * // Get an additional db
- * var testDb = db.db('test');
- * db.close();
- * });
- */
