Hi,
first post, quite new to Cocoa and Mac in general. I have an external
SQL database sitting somewhere with potentially large tables. I should
display data from the tables on an NSTableView. It should be possible to
perform sorting, searching and filtring on the data. I don't know how to
implement this efficiently with NSArrayController and bindings. I found
a short discussion about a similar problem on this list dated a few
years back. Someone suggested implementing a cache-boosted data source
that makes direct queries to the database [1]. It would allow me to have
the database sort the records for me as well as to let me populate the
table in a lazy manner (i.e. fetch the first N rows and fetch more after
a cache-miss).
I would appreaciate your comments and suggestions for alternative
approaches.
Thanks!
Dado
