Architecture of Airport Operation Database System

This paper describes the architecture of an airport operation database system (AODBS), which is the most important part of airport information integration system (AIIS) developed by the author. This airport operation database system is a distributed computing system with a multi-layer structure and connected to the rest of the AIIS through web service and message queue interface. The application modules of AODBS are written in C#, web modules written in Java and client modules written in Delphi, the modules communicate with others through web service. In the system, an object-oriented (OO) model of airport operation is developed and object relational mapping (ORM) technique is used to connect the OO model and database. The airport operation database system consists of a database server, three application servers, a web server and about 100 clients. The Architecture of AODBS described in this paper is proved to be reasonable and efficient by actual operation in the airport.
