Research And Development Of Network Database System For Ship Information

The design achievements in naval architecture field of the past years are not only the intelligence deposition, but the marvelous treasures in the line. To collect and gather these achievements helps to summarize and manage the work contributed in the past, at the same time offers reference and assistance to the increased future tasks. Therefore, an integrated and sharable ship information database with complete data, convenient searching function is needed in the naval architecture field, which has become possible to be set up and maintained with the enlarged and further using of computer technology in shipbuilding line as well as the development of network and database technology. The thesis is dedicated to study and develop the Network Database System for Ship Information according to the practical demand of ship industry.Combining the developing status of ship information database and network database technology overseas and in domestic, the software engineering idea is adopted in the process of the system studying and developing: firstly a demand analysis is done from the aspects of ship information data, function of the system and security of the system; next the general design of the system is made in accordance with the results of the demand analysis; lastly the current programming technology is applied to realize the system, and the Network Database System for Ship Information is released on Internet. The system is set up by using Windows 2000 as the software developing platform, using ASP.NET to develop the foreground network page, using IIS5.0 as the background server, using SQL Server 2000 as the database management system, and using C# as the programming language.The thesis fulfilled the work of storing miscellaneous property information of a great deal of superior ships into the database, and achieved to set up ship information database system of network version by adopting the network system framework basing on B/S(Browser /Server). The above system enables multi-users to visit the ship information data in the server database at the same time but separate places through the browser with the inquiring mode defined by themselves; and enables the system keeper to realize the long-distance maintenance to the system, including the maintenance and management to both data and database structure.The Network Database System for Ship Information saves labor and material and brings the high efficiency, in addition, the successful development of the system will propel the application of the computer technology in the field of naval architecture, which accords to the developing trend of combination between ship industry and computer science.
