Abstract: Systems and methods for lineage-aware data retention are provided. An example method includes receiving information of a committed transaction. The committed transaction is configured to add or change data to a dataset. The example method further includes receiving one or more lineages for the committed transaction, determining one or more parent transactions based at least in part on the one or more lineages, obtaining one or more parent retention dates that correspond to the one or more parent transactions respectively, and determining a transaction retention date for the committed transaction based at least in part on the one or more parent retention dates.

Abstract: Methods and systems for collaboration between two or more parties to generate a model based on data from the parties without data to the another party. A system includes an aggregation system having computer storage devices configured to store a model and a plurality versions of an aggregated model, and instructions, and one or more processors configured to execute the plurality of computer readable instructions to, iteratively, receive a first updated model from a first system controlled by a first party and a second updated model from a second system controlled by a second party, determine changes from the first updated model and the second updated model to include in an aggregated model, communicate a version of the aggregated model to the first system and a version of the aggregated model to the second system, and store a final aggregated model.

Abstract: A computer system provides transaction-level data retention policy inheritance. The system may perform operations including storing a first dataset comprising a plurality of transactions, each of the plurality of transactions comprising one or more data items; receiving a first transaction to the first dataset, the first transaction comprising one or more data items; determining a first retention policy for the first transaction; and storing the first retention policy with the first transaction. The system may further perform operations including calculating a deletion date for the first transaction based on the first retention policy; and storing the deletion date with the first transaction in the first dataset.

Abstract: A computer system is disclosed that provides purpose-based control of user actions and access to electronic data assets. For example, the computer system may perform operations including: receiving, from a user, a request to perform an action; determining any checkpoint config objects associated with the action; displaying checkpoint dialog based on checkpoint config object; determining whether criteria associated with the checkpoint object are satisfied; and in response to determining that the criteria associated with the checkpoint object are satisfied: generating a checkpoint record object; and proceeding to perform the action.
