Azure SQL Database Documentation

Overview

Azure SQL Database is a fully managed Platform as a Service (PaaS) database engine that handles most of the database management functions such as upgrading, patching, backups, and provides high availability and disaster recovery without administrator involvement.

It is built on the SQL Server engine and offers compatibility with the latest stable version of Microsoft SQL Server. This allows you to use familiar tools and skills to deploy and manage your relational databases in the cloud.

Key benefits include:

  • Scalability: Easily scale your database resources up or down based on demand.
  • High Availability: Built-in redundancy ensures your database is always available.
  • Security: Comprehensive security features to protect your data.
  • Intelligent Features: Performance insights and automated tuning help optimize your database.
  • Cost-Effectiveness: Pay only for what you use with flexible deployment options.

Core Concepts

  • Service Tiers: Understand the different performance and cost options (e.g., General Purpose, Business Critical, Hyperscale).
  • Compute and Storage: Learn how compute (vCores, DTUs) and storage are provisioned and managed.
  • Networking: Configure network access and security for your database.
  • Backup and Restore: Azure SQL Database automatically backs up your data.

Key Features

Automatic Backups

Point-in-time restore capabilities and long-term retention for compliance and disaster recovery.

Intelligent Performance

Automatic performance tuning, query performance insights, and index management.

Advanced Security

Threat detection, vulnerability assessment, transparent data encryption (TDE), and Azure Active Directory integration.

High Availability & Disaster Recovery

Built-in redundancy and failover capabilities ensure minimal downtime.

Hybrid Cloud Capabilities

Connect and synchronize data between on-premises SQL Server and Azure SQL Database.

Serverless Compute

Automatically scale compute based on workload demand and pause/resume the database to save costs.

Getting Started with Azure SQL Database

Follow these steps to quickly set up and start using Azure SQL Database:

  1. Create an Azure SQL Database: Navigate to the Azure portal and create a new SQL Database resource. Configure your server, database name, and desired service tier.
  2. Connect to Your Database: Use familiar tools like SQL Server Management Studio (SSMS), Azure Data Studio, or your application code to connect to your newly created database.
  3. Design Your Schema: Create tables, views, and other database objects.
  4. Import Data: Migrate your existing data or start populating your database.
  5. Secure Your Database: Configure firewall rules, user access, and enable advanced security features.

For detailed instructions and code examples, please refer to the Getting Started guide.
