Regressable differential data structures

At least one non-transitory machine-readable medium comprising instructions that, when executed by at least one processor;

• cause the at least one processor to perform operations to:
• identify a proposed modification to at least one record of a base data structure including a plurality of records and sorted by primary key of the plurality of records;
• identify that a differential data structure corresponds to a type of modification;
• add a first record to the differential data structure including a row within the differential data structure and describes the proposed modification;
• add a second record to a delta data structure sorted by the primary key that includes a primary key value of the second record, the type of the proposed modification, and a row number of the first record within the differential data structure;
• incorporate, upon approval of the proposed modification the proposed modification into a data model using the base data structure, the differential data structure, and the delta data structure;
• and
• delete, upon expiration of a period of time provided for approval of the proposed modification via the data model without approval of the proposed modification, both the first record from the differential data structure and the second record from the delta data structure.
