A method for facilitating usage and storage of bi-temporal data is disclosed. The method includes receiving, via an application programming interface, an update request, the update request relating to an update of a data object with a new data object; identifying a builder pattern that corresponds to the data object based on a data type of the data object; automatically generating, by using the identified builder pattern, a delta object based on the request, the delta object relating to a difference between the data object and the new data object; associating the delta object with an axial value, the axial value including a reported time and an effective time; and persisting the delta object and the corresponding association as an event that represents the difference between the data object and the new data object.
