Persisting Data in the Database

Overview

Now that our environment is ready, we’ll add a new repository to save the Pomodoro application data into SQLite. Currently, the application supports only the inMemory repository. When we add more repositories, we need to provide a way for our users to choose how to store data. We can do this at compile time or runtime.

Providing this choice at runtime makes our application more flexible, allowing users to choose which data store to use for every execution. To do this, we need to compile our application with support for all required data stores and allow the user to choose one, using command-line parameters or configuration options.
