-
-1. Create a new database named `OpenPlanetsMaps` (recommended encoding: `utf8mb4_general_ci`).
-2. Import the structure file to initialize the tables:
-   ```bash
-   mysql -u user -p OpenPlanetsMaps < SRC/DATA/Structure.sql
-   ```
-3. Then import the data file to populate the database (currently contains Earth data):
-   ```bash
-   mysql -u user -p OpenPlanetsMaps < SRC/DATA/DATA.sql
