Did research finding ways to setup a database for iOS. Looks like there are two main ways of executing this.

SQLite:

• SQLite is, as advertised, lightweight.
• SQLite uses less memory and storage space.
• SQLite can be tedious and error-prone to code.
• SQLite is supported on Android and Microsoft Windows Phone.

Core Data

• Longer learning curve: it takes some study to understand.
• Objects are easier to work with.
• Underlying storage details are handled atomically (support for iCloud).
• Undo and Redo features

Though SQLite database is the default persistent store for Core Data on iPhone, Core Data is not a relational database. It is actually a framework that lets developers store (or retrieve) data in database in an object-oriented way. With Core Data, you can easily map the objects in your apps to the table records in the database without even knowing any SQL.
