    CustomerID int IDENTITY(1,1) PRIMARY KEY,
    FirstName varchar(255),
    LastName varchar(255),
    City varchar(255)
);
    

3.8. Server Configuration

In the server configuration section, you will need to specify which accounts to use for the SQL Server services and the authentication mode (Windows Authentication or Mixed Mode). If you select Mixed Mode, you will need to set a password for the "sa" (system administrator) account. For security reasons, it is important to use a strong password.

3.9. Database Engine Configuration

In the database engine configuration section, you can configure database engine settings such as data directories, log directories, and tempdb directories. You can also configure memory settings for the database engine. While the default settings are sufficient in most cases, you can customize these settings according to your performance requirements.

3.10. Analysis Services Configuration

Analysis Services (SSAS) is a SQL Server component used for multidimensional data analysis and data mining. If you choose to install SSAS, you will need to specify the configuration options in this section.

3.11. Reporting Services Configuration

Reporting Services (SSRS) is a SQL Server component used for creating and distributing reports. If you choose to install SSRS, you will need to specify the configuration options in this section.

3.12. Distributed Replay Controller and Client Configuration

This feature is used to recreate workloads from a production environment in a test environment. You can also install this feature during setup.

3.13. Error and Usage Reporting

You can choose to send error and usage data to Microsoft. This data helps improve SQL Server.

3.14. Completing the Installation

After specifying all the configuration options, you can start the installation. The installation time may vary depending on the selected features and the performance of your system. When the installation is complete, a summary screen will be displayed. On this screen, you can check whether the installation was successful and whether any errors occurred.

4. Post-Installation Configuration

4.1. SQL Server Management Studio (SSMS)

SQL Server Management Studio (SSMS) is a graphical tool used to manage and query SQL Server databases. After installation, you can start SSMS to connect to SQL Server and start managing your databases.
