Hello,
I'm trying to figure a few things out about Document Based apps. I
understand normally there would be a file per document. For the sake
of example, if I make a simple invoice application, there will be a
CoreData datafile (XML/Binary/SQLite) with some invoice information
such as date, customer address, and items.
Now, how would this work if I wanted to have a single CoreData
datafile with multiple invoices in it? This solution makes more sense
to me as it's much easier to search, enforce unique invoice numbers,
etc. From what I can tell the CoreData Document Based app project
template expects to have file per document.
I can think of few ways around this, such as putting a small table of
existing invoices on top of each document, and thus being able to
select from multiple invoices (if I want to look in past) or create a
new invoice. Another one would be to make a separate window that
could be opened from the application menu where invoices could be
looked up and then programatically generate MyDocument windows/
objects with each invoice, however wouldn't this be breaking the
Document based design? Should I not be using document based design
for this at all?
I'm not looking for code or anything here, just trying to solve this
at conceptual level...
Thanks in advance,
mayo
