How to Download SQL Server 2019
Step 1: Choose the Edition
Determine whether you need Express, Developer, or a licensed commercial edition.
Step 2: Download From Microsoft
Use Microsoft's official SQL Server download resources and select SQL Server 2019 where available.
Step 3: Run the Installer
Launch the SQL Server setup program and select the installation option appropriate for your environment.
Step 4: Configure the Instance
Choose the default or named SQL Server instance and configure the required database-engine settings.
Step 5: Configure Authentication
SQL Server supports Windows authentication and, where appropriate, mixed-mode authentication using SQL Server authentication.
Use strong credentials and follow your organization's security policies.
Step 6: Complete Installation
Review the configuration summary and allow setup to install the selected components.
Step 7: Install Management Tools
SQL Server Management Studio can be installed separately and provides a graphical environment for managing databases, queries, users, and server configurations.
SQL Server Management Studio

It can be used to:
Create databases
Write and execute T-SQL queries
Manage tables and indexes
