Abstract: A computerized data publishing method in which an action is received from a source. The action results in a data state change that must be propagated to multiple heterogeneous computer devices, in a manner that maintains the consistency of data among multiple heterogeneous computer devices. A record is saved in storage reflecting the data state change. The update process updates the impacted computer devices with the modified data using a publishing mechanism, and receives an indicator of whether the updating succeeded or failed. If the updating failed, a retry of the updating is initiated using the publishing mechanism. If all the updating of all of the impacted computer devices succeeded, the operation ends.

Abstract: A system and method is disclosed for surveillance of financial data, comprising initiating a financial data surveillance module executable on a processor of a financial data surveillance computer system. Source data is retrieved from one or more data sources of a remote data server on which the source data is stored, the source data including transactions for a specific date and identification of the entity and account that each transaction is associated with. A metrics summary packet is generated for a particular account and the specific date, the metrics summary packet including one or more transaction classifiables that satisfy a predefined set of metric definition rules. A subjects packet is generated for the particular account that identifies the entities associated with the particular account, and a subjects-metrics packet is generated for the particular account by combining subject classifiables and metric classifiables within the subjects packet and metric summary packet.
