Instead of loading our library data from JSON or CSV files as we did in lesson_10, we now want to load data from a proper database. A new implementation of the LibraryDbDataLoader data loader has been provided to accomplish this task and is now the default data loader for the app.
To build familiarity in working with databases, you are charged with the following tasks:
.sql script file that queries the following data. Use a unique name for your file and store it in the queries directory of the resources folder.
SELECT query that returns the counts of media items by type.SELECT query that returns the sum of total pages checked out by guests.SELECT query that shows all 5 guests and any corresponding records in the checked_out_items table.library_users to the SQLite database that stores a user’s id (UUID formatted string), email, first name, last name, and a password (bcrypt encoded string). Add a model and repository that loads the users into the LibraryDataModel (see LibraryGuestModel and LibraryGuestRepository as examples). Populate the database with a few users.As before, you can run the app from the console using the following command:
./gradlew run --console=plain
