储存大量数据的最佳方法

Question

I'm working on an application that will need to pull from a list of data depending on where the user is located in the US. In a sense, I will have a database full of information based on their location, and a condition statement will determine while value from the list to use.

Example of data:

Tennessee:

   Data2 = 25;
   Data3 = 58;
   ...

Texas:

   Data2 = 849;
   Data3 = 9292;
   ...

So on...

My question is, what is the best practice to use when developing iOS apps and you have a lot of data? Should you just put all the related data in a file, and import that file when you need to like normal, or is there another method you should use? I know they state you should follow the MVC practice, and I think in this case my data would be considered the Model, but just want to double check if that applies here.

Answer 1

You have some options here:

• SQLite database
• Core Data (its not a relational database model like sqlite)
• write to plain text file. (using NSFileManager )
• NSKeyedArchiever

If you want to frequently keep appending data to a single file, I would recommend using sqlite fast and robust.
