DATANEXIS
The Inner Circle
Welcome to The Inner Circle.
I built this for people who are serious. You made it here — that already tells me something. Here is exactly what to do right now.
1
Complete your environment setup Before anything else — get your tools in place. SQL Server Express, SSMS, and the Apex Financial training database. The Setup tab walks you through it. Do not skip this step.
2
Open DN-0001 — your first real ticket This is not a tutorial. Apex Financial has a data problem and you are the analyst. Messy data, real deadline, real business stakes. This is where your transformation begins.
3
Show up to live sessions I go live every Wednesday and Sunday. Come with questions. Come with your work. This is the difference between people who learn data and people who get hired doing it.

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 ApexFinancial_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 .\SQLEXPRESS (SQL Server Express default) or (localdb)\MSSQLLocalDB if you installed the LocalDB option. Authentication: Windows Authentication. Click Connect.

Once connected, open a new query window, select ApexFinancial_Training from the database dropdown, and run this:
SELECT TOP 5 * FROM Claims ORDER BY ClaimDate 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.
