MongoDAO
Info
MongoDAO is the core of this framework. The DAO Pattern simplifies database usage.
The MongoDAO object holds a reference to a MongoCollection and adds functions for easy collection handling.
Features
- MongoDAO Base (Drop, Index, Count)
- MongoDAO CRUD (Create, Insert, Delete)
- MongoDAO Search (Search, Distinct, Aggregate)
