Using DAO ,TO Pattern without EJB

Hi,

I am developing a web application without EJB. I understand those patterns need not use EJB framework. However, it smees to me that without EJB, the role of TO may be simpler.

In my design, the meaning of TO is to separate the layer between business tier and data access tier. Upon doing some back-end enquiry, the DAO create related TO which can be translate to the business / veiw objects. And the caching will be done on Web tier but not TO layer instead.

Am I right? Would you please give some comments? Thanks a lot.
