Nowadays, data storage methods have been gone in the direction of integration with the internet structure. One of the most popularized data storage technologies is relational database. In the contrast, along with the coming of Business to Business (B2B) generation, the tendency of using Entensible Markup Language (XML) document as data exchange format recently becomes more and more evident. XML data model could be a better or suitable solution for the maritime field because ships offshore are not able to access or update database through the internet in real time. Compared with relational database, XML has the semantic advantage. This characteristic allows it to communicate with servers and to achieve the objective of automatic operations. On the other hand, because XML is built in pure text format, compared with the binary structure of database, XML takes more data storage space and has obvious backward query efficiency. In our research, in order to reduce the disadvantage of XML essence, the data storage structure for ship data modeling is investigated from query efficiency view and we apply this data model on the container operation as a sample to verify the improvement of query efficiency.
