Basic data versus fundamental difference in database?

Question

Can someone explain to me that the fundamental difference is between Core Data (apparently a “data warehouse”) and a database like SQLite or MySQL?

I am working on writing an application for the iPhone and need a static data table to display. I thought that the main data would be a good choice for this, so I got everything that was created and functioned as the database (I'm sorry - data STORE) went and then went off trying to import my data (it was into an excel file, which I exported to CSV). I thought that this should be a direct process, as I have done many times in SQLite and other databases, but as it turned out after much research, the only "official" way to do this was to write a parser specifically for my data.

When I asked about this on the Apple Developer Forums, the answer I received was basically "What an idiot you think you can import data directly without having to write code for this? Basic data is not a database - it's a data warehouse!" However, for my life I do not see the difference. In every way I looked at it, the main data behaves EXACTLY like a database, with a fancy way to access it and enough abstraction that it can use various file formats for actually storing data. In fact, I ended up being able to import my data using the simple SQLite.import command, so I really don't understand why the concept was so alien to the answers to my original question.

So what am I missing here? What is fundamentally different from a data warehouse from a database, which makes the concept of simple data import completely alien to those who know the technology?

Answer 1

Core Data is not just a means of saving / storing data to and from disk, like SQL. The Core Data true function is to provide a complete model layer for the design of a Model-View-Controller application that uses the Apple API. Since such Core Data is, first of all, a manager of graph objects with persistence parameters on the side.
