DAOs are simple java classes that has all the connection details , queries . These are used to fetch information from DB in the form of value objects.
These are used in within an EJB for getting the required results. The purpose of seperating this code from the beans is u can vary the way u retreive the information from the database as the way u get the connection and queries changes from one db to other db in that case there is no neccessity to change EJb. u can have seperate DAOs to retreive same information but suitable for different dbs S.Jagannayakam Software Developer, Wisor Telecom India Pvt LTD ., contact : 91-80-5525821 extn:4213 -----Original Message----- From: A mailing list for Enterprise JavaBeans development [mailto:[EMAIL PROTECTED]]On Behalf Of Murali Mohan Sent: Friday, November 22, 2002 11:37 AM To: [EMAIL PROTECTED] Subject: What are DAOs??
