ERECA is a HYBRID application which enables users to work independently and/or as part of a cohesive whole. This hybrid approach enables "brokers on the move" to continue their work, while sync'ing to the central system once connected to the Internet to get new updates and backup their existing system. ERECA's technology harnesses the power of a robust client server application while incorporating the mobility and widespread use facilitated by the Internet.

ERECA's central application and data servers are replicated providing real-time backup. Node connections automatically backup to the central server when they are connected via the Internet.
