Azure SQL Database is a managed relational database service provided by Microsoft Azure. It is a cloud-based service that allows you to create, scale, and manage SQL Server databases without worrying about infrastructure, patching, backups, or other maintenance tasks.
Azure SQL Database is built on the same SQL Server database engine that powers on-premises SQL Server, which means you can easily migrate your existing SQL Server databases to Azure with minimal changes to your applications.

Here are some of the key features and benefits of Azure SQL Database,
1 Scalability
Azure SQL Database allows you to scale your databases up or down as needed without downtime or data loss. You can easily change the performance level of your database based on the workload.
2. High availability
Azure SQL Database provides built-in high availability with automatic failover and geo-replication. Your data is replicated to a secondary region for disaster recovery purposes.
3. Security
Azure SQL Database provides multiple layers of security, including encryption at rest and in transit, firewall protection, and role-based access control.
4. Cost-effectiveness
Azure SQL Database offers flexible pricing options, including a pay-as-you-go model and reserved capacity pricing for predictable workloads.
5. Integration with other Azure services
Azure SQL Database integrates seamlessly with other Azure services, such as Azure Active Directory, Azure Data Factory, and Azure Functions.
To start with Azure SQL Database, you can create a new database using the Azure portal, Azure PowerShell, or Azure CLI. You can also use tools like SQL Server Management Studio (SSMS) or Azure Data Studio to manage your Azure SQL databases.
In summary, Azure SQL Database is a robust, scalable, and secure cloud-based relational database service allowing you to create and manage SQL Server databases in the cloud easily. It offers numerous benefits for developers and organizations, including high availability, scalability, security, and cost-effectiveness.
Azure SQL Database can be managed through various command-line tools. Here are some of the command-line tools you can use to manage Azure SQL Database,
Azure CLI: Azure CLI is a command-line interface for managing Azure resources. To manage Azure SQL Database using Azure CLI, you can use the "az sql" command, which allows you to perform various tasks such as creating a new database, managing server-level settings, and running queries. For example, to create a new database using Azure CLI, you can run the following command:
![Azure SQL Database]()
Azure PowerShell: Azure PowerShell is a command-line interface for managing Azure resources using PowerShell scripts. To manage Azure SQL Database using Azure PowerShell, you can use the "SqlServer" module, which provides cmdlets for managing Azure SQL Database resources. For example, to create a new database using Azure PowerShell, you can run the following command:
![Azure SQL Database]()
SQLCMD: SQLCMD is a command-line tool for running SQL queries and scripts on SQL Server databases. To connect to an Azure SQL Database instance using SQLCMD, you can use the following command
![Azure SQL Database]()
Azure SQL Database provides multiple layers of security to protect your data and applications. Here are some of the key security features of Azure SQL Database,
1. Encryption
Azure SQL Database encrypts data at rest and in transit. Data at rest is encrypted using Transparent Data Encryption (TDE), which encrypts the entire database, including backups. Data in transit is encrypted using SSL/TLS.
2. Firewall protection
Azure SQL Database provides firewall protection to restrict access to your databases. You can configure firewall rules to allow or deny access based on IP addresses or ranges.
3. Authentication and authorization
Azure SQL Database supports Azure Active Directory authentication and SQL Server authentication. You can also use role-based access control to manage user access to your databases.
4. Threat detection
Azure SQL Database includes built-in threat detection using machine learning to detect anomalous database activities, such as SQL injection attacks and login attempts.
5. Auditing and compliance
Azure SQL Database provides auditing and compliance features to help you meet regulatory requirements. You can enable auditing to track database activity and store audit logs in Azure Storage. Azure SQL Database supports various compliance certifications, such as ISO, SOC, and HIPAA.
6. Data masking
Azure SQL Database supports data masking, which allows you to mask sensitive data in query results. You can configure data masking rules to mask specific columns based on user roles or permissions.
7. Always Encrypted
Azure SQL Database also supports Always Encrypted, allowing you to encrypt sensitive data at the application level so that the data is never exposed to the database engine or administrators in plaintext.
In summary, Azure SQL Database provides multiple layers of security to protect your data and applications. These security features include encryption, firewall protection, authentication and authorization, threat detection, auditing and compliance, data masking, and Always Encrypted. You can build secure and compliant applications on Azure SQL Database by leveraging these security features.
You can then run SQL queries and scripts against the connected database.
Summary
In summary, Azure SQL Database can be managed using various command-line tools, including Azure CLI, Azure PowerShell, and SQLCMD. These tools allow you to perform various tasks, such as creating a new database, managing server-level settings, and running SQL queries and scripts.
