In order to solve the problem of marine product data of multi-source heterogeneous and make users to manage a large number of complex ocean product data effectively, we design and implement a set of marine product information management system. First ,we introduces the system architecture, and then give exposition to each module in detail, and carry on the detailed analysis of the Marine data, aiming at the problems in marine product data such as the data inconsistency ,the gap and redundant data, we use time series of anomaly detection method based on cumulative variation, it can detect the abnormal point in the ocean data effectively, and modify abnormal points again, then guarantees The quality of the Marine data, thereby a set of perfect Marine product information management system is established, it makes the related department of Marine business process more scientific and standardized.
