// Database Adapter
|
|
//
|
|
// Allows you to change the underlying database.
|
|
//
|
|
// Adapter classes must implement the following methods:
|
|
// * a constructor with signature (connectionString, optionsObject)
|
|
// * connect()
|
|
// * loadSchema()
|
|
// * create(className, object)
|
|
// * find(className, query, options)
|
|
// * update(className, query, update, options)
|
|
// * destroy(className, query, options)
|
|
// * This list is incomplete and the database process is not fully modularized.
|
|
//
|
|
// Default is ExportAdapter, which uses mongo.
