Before connecting Power BI to both a local SQL Server and a cloud-hosted Aiven PostgreSQL database, you'll need a few tool with each playing a specific role in making the setup secure.
- Power BI Desktop – The business intelligence tool used to connect to databases, transform data, and create interactive dashboards and reports.
- Aiven Account – Hosts your PostgreSQL database in the cloud and provides the connection details needed to access it remotely.
- Aiven SSL Certificate – Encrypts the connection between Power BI and the Aiven PostgreSQL database, ensuring your data is transferred securely.
- PostgreSQL – The database management system used to store and manage your data. In this guide, you'll work with both a local PostgreSQL installation and an Aiven-hosted PostgreSQL database.
- DBeaver – A free database management tool that lets you create, view, and manage your databases before connecting them to Power BI.
With these tools installed and configured, you're ready to connect Power BI to both local and cloud-based databases .
Difference Between Local SQL Server and Aiven PostgreSQL with SSL
A local database runs on your own computer or within your local network, so Power BI can connect to it directly using the server and database name. In contrast, an Aiven PostgreSQL database is hosted in the cloud and accessed over the internet. Because the connection travels across public networks, SSL (Secure Sockets Layer) encryption is required to protect your data and verify the identity of the server. While both connections allow Power BI to retrieve and analyze data, the cloud connection requires a few extra security steps to ensure your data remains safe during transmission.
Connecting Power BI to a Local SQL Server Database
Step 1: Open Power BI Desktop
Launch Power BI Desktop and select Get Data from the Home tab.
Step 2: Choose SQL Server
Search for PostgreSQL Database, select it, and click Connect.
Step 3: Enter the Server Details
Type your SQL Server name . Optionally,you can enter the database name if you want to connect directly to a specific database.
Step 4: Select the Authentication Method
Choose either Windows Authentication or Database Authentication, depending on how your SQL Server is configured.
Step 5: Connect to the Database
Click Connect. Power BI will establish a connection and display the available tables and views.
Step 6: Load or Transform the Data
Select the tables you need, then click Load to import the data or Transform Data to clean and shape it before loading.
Step 7: Start Building Reports
Once the data is loaded, you're ready to create visualizations, dashboards, and reports in Power BI.
Connecting Power BI to an Aiven PostgreSQL Database with SSL
Step 1: Download the Aiven SSL Certificate
From your Aiven project, download the CA Certificate (ca.pem) needed for SSL authentication.
Step 2: Install the PostgreSQL Driver
Ensure the Npgsql PostgreSQL driver is installed so Power BI can connect to PostgreSQL databases.
Step 3: Open Power BI Desktop
Launch Power BI Desktop and click Get Data.
Step 4: Select PostgreSQL Database
Search for PostgreSQL Database, select it, and click Connect.
Step 5: Enter the Connection Details
Enter the host name, port, and database name provided by Aiven.Simply just copy paste the details in the right dockets.The keys windows+V come in handy in this place.
Step 6: Configure SSL
First search manager user certificate on your search bar, click on it,then click on the drop down of Trusted Root Certification ,right click on the certificate option, then click on All Tasks ,then click on import ,click on the option Next and then browse on the downloaded ca.pem certificate, and ensure the connection uses SSL encryption.
Step 7: Enter Your Credentials
Provide your Aiven username and password, then click Connect.
Step 8: Load or Transform the Data
Choose the tables you want to use, then click Load or Transform Data to prepare the data before importing it into Power BI.
Step 9: Build Your Reports
Once the data is loaded, you can begin creating dashboards, charts, and reports using your cloud-hosted PostgreSQL data.
