21. Commercial fleet management system
Server architecture
Advantages of the server architecture
The security of the stored and exchanged information is guaranteed by the strict rules of the safety management of the database handler and Java environment.
As a result of the database-centered architecture, the servers can be developed independently on arbitrary platforms by different groups and the updated modules can be inserted into the system without interrupting the operation.
In the case of increasing demands the modules of the centre can be easily multiplied.
Every user has individual web interface, which contains the services the user needs or has subscribed to.
