This dual purpose service component compares one or more given datasets with one or more Concert datasets and provides a list of differences which can be notified to a client system. Alternatively a single merged dataset representing a union of the identified data sets can be returned in a bulk form.

Datasets can be manually reconciled (by the user) or automatically reconciled according to provided rules. This capability is also sometimes referred to as a data-differencing or data-synchronisation service.

Any given solution using this component will also require 1 broker, and 1 or more collection or reception service components configured as part of a solution assembly.

Solutions may optionally benefit from 1 or more data hubs being deployed, enabling data collected or processed to be shared by other solutions.
