Hello Everybody,
    I am designing an application where there are a lot of database
operations, viz. query, insert, update, delete. I have a design problem.

    I have created a DB class which has a method which does all the
insert update and delete operations. Whenever I want to insert,  update
or delete a record, should I create a new instance of my DB class and
call it's method, OR create one instance of DB class per table OR make
my method in the DB class static. What are the design issues to be
considered?

    A lot of people have access to the same screens. How do I make sure
that the user is viewing the latest data at any stage?

    Thanking u in advance,
Kiran
