Abstract: Code and data versioning allow developers to work on code and data without affecting production code and data and without affecting the development activities of other developers. Code and data being worked on by a developer are associated with a task. The system automatically determines the dataset to use for a given development task from among a production dataset, a latest dataset, or a temporary dataset associated with the development task so that development code does not have to be modified to read from a specific dataset.
