Hi All,
Can anyone suggest me a framework that can abstract the data call and
its source, if there exists any? Example if I want to authenticate a
user then my query shall not depend upon the data source, it could be

Use a Data Access Object (DAO) to abstract and encapsulate all access to
the data source. The DAO manages the

How about an object factory?
Interface - UserAuth
Implementation - LdapAuth implements UserAuth
Implementation - SqlAuth implements UserAuth
Factory (pseudo code):
if(ldap) {
return(new LdapAuth);
}
else if(sql) {
reutrn(new SqlAuth);
}
etc.
