Hi all.
I think this is kind of a basic question. I have an application that
haves 3 tables: users, messages and user_inbox for the relationship of
first 2 ones. I have a class named MessagesManager in order to manage
the messages to-and-from the database throught the business methods, one
of them is the public List getMessages(String user_id) method that
returns a MessageBean's list and I need to display the messages of each
user in a html table, the MessageBean only contains the user_id but I
want to display their names, do I need to modify my business method in
order to get the usernames? or do I need to add another method to get
the usernames, something like public String getName(String user_id)?,
the first aproach makes one query to the database and the second aproach
makes two. What is the best practice here?
As you can see english is not my navite language, I hope you guys can
understand my issue.
Thanks in advance.
Have a nice weekend.
