nosql_repository library
Repository pattern for NoSQL databases
The purpose of this package is to define a structure of an interface to access a NoSQL database. The main abstraction it defines is the Repository class. The Repository class represents a set of operations that are used to access a collection in a database, which include the typical CRUD methods (Create, Read, Update and Delete).
The Repository is abstract. The goal is to create concrete implementations of it, but reference the abstract class throughout the code of the application, therefore abstracting away as much as possible the concrete database engine.
