i think the 'right' method to do this is to have an array of views. it
makes sense that your 'document' is the whole database. then what you are
really doing is creating multiple views of the data. while one use of this
is to create views that are different ways to display the data it can also
be used to display different sections of the same document in copies of the
same type of view. this would be like opening two views of a word document
in the application and scrolling each one to a different part of the
document.
