The specific architecture is as follows Figure 6 As shown:

[0061] The integrated oceanographic simulation system is centered around a server. The digital surveying and mapping simulation system and the online web data management system are connected to the server via a local area network. The server receives requests from users and administrators, submits requests to the server over the network, and performs database operations. The server accepts requests from the digital surveying and mapping simulation system or the online web data management system and submits data to the client and web client. The client then analyzes and calculates the data and presents the results to the user. The server also provides comprehensive security protection, ensures data integrity, and allows multiple clients to access the server simultaneously.

[0062] The online web management module is built based on the web backend management and is only used by administrators to log in. The administrator interacts with the server through the web terminal to operate and manage the database. Its architecture is as follows Figure 7 As shown:
