Data Base Research(iOS)

We conducted a study for two most popular DataBases with encryption: Realm and SQLite + SQLCipher.

*If your project requires encryption or speed, then Realm is an obvious choice. If your project has a complex data model that changes frequently, then Core Data might be a better choice. Proof of concept

In our study we make 100 0000 of inserts for both db.

Device	DataBase	Write 100K	Read 100K	get id = 25000	get id = 50000	get id = 750000
