As we know, Relational databases are the best for managing structured data via schema, constraints, and Relationships, being rich in Query capabilities.
Connection String in Azure SQL Database:
- The Connection String is used to connect to the database, which typically contains authorization credentials like username, password, etc. The connection string is directly available in the SQL options after creating the database and this connection string is available in various types based on the programming language we use. In this article, let us understand how to get Azure SQL database connection string. First, let us start with creating an SQL database in Azure.
Step-By-Step Approach To Create an SQL Database
Step 1: sign in to your Azure portal with an active subscription.
Step 2: Navigate to the databases, under that click on SQL Databases
Click on the create SQL Database.
Step 4: Follow the below instructions to create SQL Database.
Basics Tab:
- under the project details, choose your subscription.
- Create a resource group or use existing resource group for your database.
Under the Database details, enter the database name and Server name. As there is no existing server, Let me demonstrate the creation of SQL Database Server.
Step 3: Creation of SQL Database Server. Under the Server details, enter the Server name and location
Mention the Authentication details. Here I am using SQL Authentication. Enter the Admin username and password and confirm password. click ok.
Choose the SQL elastic pool if you need to manage multiple databases with shared resources and choose the workload environment.
choose the Backup storage redundancy method.
Now, click Review + create. You will be displayed with all the information along with billing details. click create. Now, your resource will start deploying.
Get Azure SQL database connection string:
After your resource is deployed. Click on the Go to Resource button.
Choose see connection strings option to get Azure SQL database connection string.
or click connection strings under the settings in the left menu.
Here, we can find different versions of connection strings for different technologies like JDBC, ODBC, PHP, GO, .NET. The connection strings are therefore used to connect the SQL database with your application of related technologies.
Deployment Models in Azure SQL Database
1. Single Database
Description: A Single Database in Azure SQL Database is a fully managed and isolated database. It operates independently and has its own set of resources, making it suitable for applications with varying performance and resource requirements. It provides optimal control and customization for a specific database workload.
2. Elastic Pool
Description: An Elastic Pool in Azure SQL Database is a collection of single databases that share a set of resources. This deployment model is designed to efficiently manage and allocate resources among multiple databases, allowing for cost-effective utilization. It is ideal for scenarios where individual databases have fluctuating resource needs, and resource sharing enhances overall efficiency.
3. Managed Instance
Description: A Managed Instance in Azure SQL Database is a fully managed instance within the SQL Server infrastructure. It offers compatibility with on-premises SQL Server features, providing a broader range of migration options for existing applications. Managed Instance is suitable for scenarios where you need the flexibility of a SQL Server instance but prefer a fully managed service in Azure, including automatic backups, patches, and updates. This deployment model bridges the gap between traditional SQL Server and Azure SQL Database.
