Abstract
The traditional method of managing public transportation information first takes more time, and secondly, the data error rate is relatively high, and it is more difficult to modify the wrong data, and finally, it is laborious and laborious to retrieve the data. Therefore, installing the public transportation query website software on the computer to play its role in efficient information processing can standardize the public transportation information management process, so that the management work can be systematized and programmed. At the same time, the effective use of the public transportation query website can help managers accurately Process information quickly.
The public transportation query website is also very cautious in the selection of development tools. In order to facilitate the development and realization, the selected development tool is Eclipse, and the selected database tool is Mysql. In this way, the development environment is built to realize the functions of the public transport query website. Among them, the administrator manages users, drivers, news announcements, manages vehicles, stations, and trip information in the route management module, and responds to users' suggested messages in the message suggestion management module. Users inquire about the site, inquire about transfer information, post message suggestions, and check news announcements.
The bus query website is an application system designed and implemented using software development technology. It can achieve rapid information processing. Whether it is for data addition, data maintenance and statistics, and data query processing requirements, the bus query website can easily response.
Key Words****：Public transport query website; bus number information; suggestion to leave a message; query site
