The components

A client/server architecture consists of several parts:

To implement a client/server database, each of the components above must be implemented; either using existing software or by writing new code. We designed a new client/server system primarily in order to implement our own secure protocol. Accordingly, we wrote our own code to handle the database communication protocol. The other components are off-the-shelf, in order to reduce the programming work.

The following are the components used in our system:

Location Component Technology
Client operating system Win32
network communication package TCP/IP + SSL
client DBMS communication package Our own code
graphical user interface Zinc
Network protocol TCP/IP
Server operating system Linux
network communication package TCP/IP + SSL
database protocol + support code Our own code
authentication module Our own code
access control / logging module Our own code
package for physical DBMS access CodeBase

The architecture is illustrated in Figure 1.
