摘要
海洋数据具有规模庞大、种类繁多、结构复杂、时空特性明显等特征,如何高效地对海洋中的大数据进行存储是实现我国海洋数字化以及管理的科学化的关键。传统的数据存储系统面临着高扩展性、高可靠性、高安全性和低成本的挑战。阐述海洋数据的特征,制定海洋中大数据的生命周期;根据海洋中大数据的生命周期图,设计出一种适合于海洋大数据特征的迁移模型,解决了海洋中大数据在分级存储中的数据迁移问题,实现了海洋大数据的高效存储。
Marine data has the characteristics of large-scale, various types, complex structure, distinct spatiotemporal feature, and so on, it is the key to realise the marine digitisation and scientific management in our country in the way of efficiently storing the marine big data. Traditional data storage system encounters challenges including high scalability, high reliability, high security and low-cost. In the paper we first expound the characteristics of marine data, and then lay down the lifecycle of marine big data. Based on the lifecycle diagram of marine big data, we design a migration model suitable for it, this solves the problems of migration of marine big data in hierarchical storage system and realises efficient storage for marine big data.
