Neither is “better”. It boils down to tradeoffs amongst the advantages and disadvantages of each compared to your situation and your needs. From a technical standpoint, the differences are these: A self-serving 4GL client or old appserver agent or a pasoe multi-session agent combines the 4GL client database interface and logic with the database server side logic. the client side communicates with the server side by means of subroutine calls which are quite efficient since there is no inter-process or inter-machine communication involved. client, server, and database all have to be on the same machine. A network 4GL client communicates with a separate database server (running on the machine hosting the database) that accesses the database on behalf of the client. The client and server can be executing on the same machine or separate machines. The two parts communicate by means of messages exchanges over a TCP/IP network connection (other network protocols were supported in the past but no needs those anymore).
