What is 4DF????
4DF is a Library that manages your applications interaction with the database, providing ORM, database abstraction and 4DF or 4th Dimensional Form data which means that all data is saved in every state in every table over time. Nothing is ever deleted or updated, and you do not need to anything to implement this behavior, it happens automatically. It also provides a basic service layer for accessing your data through time, allowing you to retrieve current and historical data and filtering by time ranges.
