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.
