Foil 3 Traditional Web/RDBMS access Compared to using Java

From Overview of JDBC: Java Database Connectivity Basic Information Track Computational Science Course CPS616 -- Spring Semester 1999. by Nancy McCracken,(Sangetta Aggarwal, Meryem Ispirli, Udayan Parvate, Tom Pulikal, Chao-Wei Ou)
Traditional web access to the database was done with the use of CGI script accessing the database and creating output in the form of HTML document presented in WWW client.
The requests and responses were transmitted using HTTP protocol and there was no session notion and it was not able to preserve the database transaction logic
JDBC expands these options:
Java programs can be executed on client and on server side. In this case it is possible to create three tier client-server application.
Client applications can also access database directly.
