The most common way to implement database functionalities in iOS applications is definitely Apple’s Core Data. However, its architecture is really Apple-like: it doesn’t let you see anything happening inside and the structure is hidden from you. That’s why some people dislike Core Data and prefer to stick with an SQLite database – even though SQLite is not supported natively. Fortunately, you are not forced to use core SQLite API in pure C.
Although mobile apps do not rely on databases as much as, say, web applications, mobile app developers should still be interested in databases. There are better database solutions for Android apps than a native SQLite library; we’ll nominate ORMs (Object Relational Mapping) as one of them. ORMs make developers’ lives easier. They let us avoid struggling with building queries by concatenating strings or manually handling the connection with database. Typos are less of threat to your queries.
