Role-based user tracking in service usage

Devising a centralized usage database for tracking and recording the usage of various services by various users may be difficult for several reasons, including the volume of data generated by each user in interacting with each service. Techniques are disclosed for streamlining usage data transmitted between the services, the users, and the usage database, such as by redistributing a portion of the computational burden to the users, and by characterizing the usage data based on the role of each user in interacting with each service. Additional techniques are disclosed for caching and authenticating the usage data, and for improving the response rate in the interaction of the usage database with users in order to provide a better user experience.
