| Cogent's Cascade DataHub accepts and retransmits data from and to any client program registered with it, in real time. Its asynchronous communication protocols allow for two-way exception-based messaging between all registered clients on any specified data points. This eliminates roblems associated with synchronous polling techniques, and permits building applications with open modular architectures. The DataHub is not a relational database, but rather optimizes a flat database design for rapid distribution of data. |
