The Wonderware eDNA archive is an extremely high performance real-time database for storing streaming data from control and monitoring systems and devices. The eDNA archive technology uses advanced real-time data compression technology to store this information efficiently. The data compression fully maintains the fidelity of the collected information (lossless data compression) and can achieve compression ratios of over 30:1. In comparison other lossy methods of data compression are often practiced for storage of large amounts of streaming data making the exact recreation of all events at a specific point in time impossible to achieve. The eDNA archive technology provides the ability to store years to decades of high fidelity data online while maintaining the very fast data retrieval that is necessary for timely analysis and decision making.
