Abstract: This disclosure describes one or more implementations of a data verification system that provides accurate validations of user trait data for data providers. For example, in various implementations, the data verification system generates and utilizes data verification models and approaches to determine the probability that user trait data obtained by data providers is accurate and correct. In this manner, the data verification system can independently evaluate the accuracy of both individual user records as well as collective segments of user records for data providers.

Abstract: Computing systems methods, and non-transitory storage media are provided for receiving a monitoring request. The monitoring request includes one or more entities or attributes to be monitored, one or more rules to be evaluated with respect to the entities or attributes, and one or more downstream actions to be selectively triggered based on the evaluation. Next, data regarding the entities or the attributes is obtained. Next, a log is generated. The log includes changes or updates, relative to a previous iteration, of the entities or the attributes. The changes or updates correspond to the rules. Next, the changes or the updates are evaluated against the one or more rules and based on the log. Next, one or more actions are selectively implemented based on the evaluation of the changes or the updates.

Abstract: Whether a logical query plan to derive a target dataset from one or more source datasets is available is determined. Responsive to determining that the logical query plan is not available for the transformation code in the first programming language, relationships between the source columns of the one or more source datasets and the respective target columns of the target dataset are inferred. Target column metadata for a target column of the target dataset is generated. The target column metadata reflects the inferred relationships between the source columns of the one or more source datasets and the respective target columns. The target column metadata for the target column of the target dataset is stored.

Abstract: A logical query plan to derive a target dataset from one or more source datasets is identified. The logical query plan defines source columns of the one or more source datasets and respective target columns of the target dataset. The logical query plan is parsed to derive relationships between the source columns of the one or more source datasets and the respective target columns of the target dataset. Target column metadata is generated for a target column of the target dataset. The target column metadata reflects a derived relationship between one or more source columns and the target column and existing source column metadata of each of the one or more source columns. The target column metadata is stored for the target column of the target dataset.
