I have read about CMP and DAO, and Some people said that when I use CMP, DAO
don't make sense...
But
What if I want to have the possibility to change to JDBC DAO for sample ?
I would have to change all my business method, wouldn't I ?
But If I make a DAO like this:

public class EJBFamilyDAO implements IFamilyDAO {

Context context = null;
FamilyHome home = null;

/*
* (non-Javadoc)
*
* @(protected)
com.shoptime.integration.crmerp.persistence.IFamilyDAO#insertFamily(java.lang
.String)
*/
public void insertFamily(String pFamilyName) {
// TODO Auto-generated method stub
home.create(pFamilyName);
}

/*
* (non-Javadoc)
*
* @(protected)
com.shoptime.integration.crmerp.persistence.IFamilyDAO#findFamilyByName(java
.lang.String)
*/
public FamilyVO findFamilyByName(String pName) {
// TODO Auto-generated method stub
return home.findBFamilyByName(pName);
}

public EJBFamilyDAO() {
try {
context = new InitialContext();
home = context.lookup(...);
} catch (Exception e) {
e.printStackTrace();
}
}

}
Wouldn't it be more easy to change my business method? I only need change my
DAO Implementation, don't I ?

Thanks in advance
