# Banking System Test Database Generator
# This program generates a test database for the banking system. The database contains 50 clients, each with 2 accounts. Each account has 40 transactions.
# The first client is an administrator. The password for the administrator account is "Happymeal1". The program uses the Faker library to generate fake
# data for the clients, accounts, and transactions. The random library is used to generate random data for the accounts and transactions. The program
# creates a new SQLite database called test_database.db and writes the test data to the database. The client ID of the administrator account and the
# password for the administrator account.
ADMIN_EMAIL = "lmath56@hotmail.com" # Email address of the administrator account
