Along with the appearance of distributed concept, traditional centralized management framework has been transferred to distributed management framework, especially in electronic commerce field. In the technical implementation level, because relational database technology is already very mature and easy to be implemented in distributed construction, so nowadays electronic business enterprises mostly use relational database management system (RDBMS) to store and manage their data. Although, in fleet management, because of ships cannot access to centric database through general internet construction when they are offshore, the data belong to ships themselves have the necessity of independent self-management. But RDBMS cannot completely satisfy this objective because it is not easy to be divided. In this paper, we propose to use Extensible Markup Language (XML) to construct ship data management model, so then it could be applied for fleet management and future port administration. The data model can be composed of many kinds of information, such as hardware (ship name, ship type, net tonnage, etc), software (schedule, service, passenger, etc) and freight (freight kind, freight charge, deliver country, etc). Multi-level data model can provide the ability for fleet inter-manageinent and communicating function to government related departments for port administration.
