Abstract
A client-server computing system is disclosed for supporting relational database records and linked external files. The system comprises one or more servers for storing external files, and a plurality of clients interlinked by a network. Each of the servers and certain of the clients have respective filter layers for controlling servicing of application requests relating to external files, for any application command of a protected class relating to an external file made to a client having a filter layer, the respective client filter layer determines the presence of a valid user token associated with the command, then passes the command to a server across the network. The server filter layer, if it recognizes the command, causes the command to be serviced by the server. However, for any application command of a protected class relating to an external file made to a client not having a filter layer, the command will be forwarded across the network to the server filter layer of a server holding the external file and the server filter layer will block the command from being serviced.
