Abstract: This is a worker related data management system for efficiently collecting data, moving data, and executing decisions based upon signals and inputs of various parties who have access to information stored at some central database location. Key to the system and method is a reliable infrastructure for determining that communications with the system originate from parties who have been granted access to produce such communications. Such infrastructure enables an efficient system and method for tracking information and making management decisions, such as decisions to cause payment of a supplier, without the same level of checking required by prior existing systems and methods.
