Hey everyone
I have made my way through the documentation to core data and am really
excited to start using it. I have a couple of Q's about if my particular
scenario is appropriate for core data, or if I'm forcing the wrong
technology for the job. I suspect that discussing anything related to sdk
iphone 3.0 is off limits, so i will skirt around that. If this type of talk
is allowed please let me know and I can elaborate on my poblem.
1. For my theseis project I am writing software that wil help visually
disabled people use public transit through the use of modile devices. For
this stage, lets assume I'm talking about a prototype on the mac desktop.
The transit authority has given me scheduling data in the form of multiple
txt files. I have written python scripts to extract the data from these
files and crate a SQlite database. With indexes this database is about 70
MB. Now, after reading Marcus Zarra's core data book, and some of the docs,
I really like how data can be accessed in an object-like way, and not an sql
way. My idea was to pre-load a core data store up with this transit info
and distribute the app accordingly. I have two concerns that lead me to
believe that core data may not be appropriate. First, this data is never
modified by the user, its just a store of data that is used to find bus
times. Second, since the db is so large, I dont want to incur unnecessary
processing. Like I siad, I would generally like to avoid the sql api and
use the features of core data, but my question is, is this overkill?
2. This may crossing nda lines, so please ignore if inappropriate. My
question is, if i created this core data store targeted for a mac
application, would the store itself be compatible with core data on the
iphone? The tutorials on the iphone core data are significantly different
than for the mac, especially since bindings are still not around.
Thank you for your advice.
