Generic connector module capable of integrating multiple applications into an integration platform
A generic connector module of an integration-platform system reconciles the system's application-independent canonical API with each application-specific API used by an endpoint application. The system generates a software library of application-specific configuration files each capable of enabling the connector to translate commands between one application-specific API format and the canonical-API format. Applications may be added to the system, removed, or updated without revising the connector. When the connector receives an application-specific request from an application or a canonical request from the integration platform, the connector selects an application-specific configuration file that lets the connector translate the received request into its complementary API format. The connector then forwards the translated request to its intended recipient. A converse process occurs when receiving an application-specific or canonical response to the translated request. Translations can be performed dynamically, in real time, without requiring a distinct connector module dedicated to each application. |

The D Field states the number of bits in the floating point representation that are no longer meaningful. The bounds on the represented real value are determined by the truncated floating point value and the addition of the error determined by the number of lost bits. The true, real value is absolutely contained by these bounds. The allowable loss (optionally programmable) of significant digits provides a fail-safe, real-time notification of loss of significant digits. This allows representation of real numbers accurate to the last digit. |
