Application Pattern



Hi,

We have a java application which uses the following:
JSPs/HTML/Servlets for presentation
Servlet with methods having database queries which make JDBC connection
Oracle DB

When a request/action takes place on jsp/html.. the request isa sent to Servlet method.... in the Servelt method...the jdbc connection is made and then query is run on Oracle DB .. the result it returned to Servlet..and back to jsp.

I am confused under what design pattern or architecture the above application falls? As of now the number of users are say 200.. Will there be any problem with about design.. if the users increase tomorrow ...any scalability issues?

Please help
