Abstract: Systems and methods are provided for transforming data stored in an operational database to a format/structure optimized for use in a data lakehouse. The data transformation is metadata-driven, where the metadata characterizing the transformation of data may be automatically generated via the performance of various denormalization/modeling techniques, including: path/edge/tree/log denormalization, and state machine/aggregate/adaptive modeling.

Abstract: Systems and methods are provided for data drift detection and reconciliation by establishing ground truth through the determination of any changes in the source data via restored current and previous snapshots of an operational/transactional database. Changes in lakehouse data can be identified via the use of raw data events from which reconstructed tables are determined, and changes in business intelligence tables can be identified based on the application of data mapping rules to the raw data events, such that these changes can be compared to determine if data drift has occurred.

Abstract: A computing system comprises, in one example, a user interface component configured to generate a data security configuration interface that displays user input mechanisms and receives user configuration inputs, and a data security component configured to control user data access. The data security component comprises a plurality of configurable security objects arranged in a security hierarchy. The configuration inputs associate at least one user with each security object in the security hierarchy to define a data access relationship between the users associated with the security objects. The data security component comprises a data access component configured to receive a data access request from a given user, identify a set of users that are associated with security objects in the security hierarchy relative to a security object to which the given user is associated, and provide the given user with access to data objects that are associated with the set of users.
