Abstract: The disclosed embodiments provide a system for processing data. During operation, the system obtains a first transaction timestamp from a record that is replicated across a set of data sources. Next, the system includes at least a portion of the first transaction timestamp in a first key of a first mapping of the record to a first set of values for the record from the set of data sources. The system then audits the record by comparing the first set of values in the first mapping. Finally, the system outputs a result of the audited record based on the compared first set of values.

Abstract: The disclosed embodiments provide a system for processing data. During operation, the system obtains input data containing a set of replicated records from a set of data sources. Next, the system generates, in a data store, a first mapping of a first key to a first set of values for a first replicated record in the set of replicated records. The system then audits the input data by comparing the first set of values in the first mapping. Finally, the system outputs a result of the audited input data based on the compared first set of values.

Abstract: System and methods for generating personalized skill and learning recommendation are disclosed. A social networking system determines a list of skills not yet acquired by a first member. The social networking system determines a value associated with each skill. The social networking system selects one or more skills the list of skills based on the determined value of each skill. For each selected skill, the social networking system identifies at least one educational opportunity associated with learning the selected skill. The social networking system ranks the selected skills based on the determined value associate with each skill. The social networking system transmits a skill recommendation for an educational opportunity based on the selected skill rankings to a client system associated with the first member for display in a user interface.

Abstract: A data query system is provided, which comprises: a data storage; a load server communicatively linked with the data storage and configured to store a plurality of data in the data storage as read-only data, and publish the plurality of read-only data; and a query server separate from the load server and communicatively linked with the load server and the data storage and configured to subscribe to the publication of the plurality of read-only data from the load server, and query the published plurality of read-only data to which it has subscribed in response to a query request.
