Environment Setup

Do this once. Then never think about tools again.

1
Install SQL Server Express
This is your local database engine. Free. From Microsoft. Takes about 5 minutes to install. When prompted, choose Basic installation. Everything else — default settings.
↗ Download SQL Server Express
2
Install SSMS
SQL Server Management Studio. This is the tool you will write every query in. Download the latest version. Installation is straightforward — all defaults are fine.
↗ Download SSMS
3
Download the DataNexis Training Database
This is your practice environment. Every ticket in Phase 01 runs against this database. Download the script, open it in SSMS, and run it. It creates everything automatically.
↓ Download DataNexis_Training.sql
⚠ Make sure SQL Server Express is installed before running this script.
4
Connect in SSMS and Verify
Open SSMS. In the connection dialog, set Server name to your machine name or (localdb)\MSSQLLocalDB for a default Express install. Authentication: Windows Authentication. Click Connect.

Once connected, open a new query window, select DataNexis_Training from the database dropdown, and run this:
SELECT TOP 5 * FROM Orders ORDER BY OrderDate DESC;
If you see 5 rows — you are ready. Go hit DN-0001.
You're set up.
Write your SQL in SSMS. Paste your final query into the ticket. Submit. Caesar reviews it.
