Two-tier model Of JDBC

In two tier model, Java Application communicates directly to the data source. User commands are delivered to the database using JDBC driver and results of those commands are sent back to the user. It is not necessary that both Java application and data source in same machine. They can reside anywhere.




The major problem with two-tier model of jdbc is, it is fine when concurrent number of users accessing your application are less. But it is problematic, when number of users accessing your application becomes more and more.
