Abstract
A system, a method and a computer readable medium for storing data elements and related data provenance information. The data elements may be represented in a hyper-table having rows and columns which may be indexed. The data-values of the corresponding data-elements in the hyper-cells may be retrieved based on the indices. Snapshots of the indices may be generated at pre-determined time periods. Checkpoints of the hyper-table may be generated at time periods that are based on transactions on the hyper-table. The hyper-table is capable of being queried as the hyper-table existed at certain time-periods, and data-values of the data-elements may be retrieved as the data-elements existed at such time-periods.
