Core Data Framework Database
Core Data Framework Databases are essentially just a SQLite Database
Core Data is a framework that is used to manage the model layer objects in the application. It provides generalized and automated solutions to common tasks associated with object life cycle and object graph management, including persistence.
The databases it uses are sqlite3 databases and can be inspected in the app's sandbox folder again under the Library/Application Support folder.
