Installing SQL Server Express and SSMS
You'll need a real SQL Server engine (not just LocalDB) for the SQL Server module later, plus SQL Server Management Studio (SSMS) to manage it visually.
What is SQL Server?
SQL Server is Microsoft's database system. SQL Server Express is the free version. SSMS is the tool you use to manage it.
Step 1 — Install SQL Server Express
Download SQL Server Express (free) from Microsoft's SQL
Server downloads page. Choose the "Basic" installation type — it configures
a working default instance automatically, usually named
localhost\SQLEXPRESS.
Step 2 — Install SSMS
SSMS is a separate download: search "Download SQL Server Management Studio." Install it, then open it and connect using:
Server name: localhost\SQLEXPRESS
Authentication: Windows AuthenticationStep 3 — Verify the connection
Once connected, expand Databases in Object Explorer. You should see the system databases (master, model, msdb, tempdb). If you can see these, your installation is working.
Key Takeaway
SQL Server Express is free and powerful. SSMS is your visual tool for managing databases.
