Advantages of the server architecture
T
 The security of the stored and exchanged information is
A
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.
