Prerequisites

Accounts Needed

You need some accounts before you begin. Here is what you need:

1. An Azure subscription lets you make Synapse Analytics resources.

2. An Azure Active Directory (Azure AD) account controls who can use your Synapse workspace.

3. A Power BI account lets you sign in to Power BI Desktop and connect to Synapse data.

Tip: Use the same Azure AD identity for your Power BI account and Synapse workspace. This helps you not have sign-in problems.

Permissions Setup

You must give the right people access to keep your data safe. Here are the steps:

1. Add users to Azure AD and put them in security groups like SynapseAdministrators or SynapseContributors.

2. Give these groups roles in Synapse, such as Contributor or Viewer.

3. Set SQL permissions for Synapse SQL pools. Assign db_datareader if users need to read data.

4. Put users in the right security groups to make things easier.

5. Protect your workspace with firewall rules or private endpoints.

Tools Required

You need some tools to link Synapse Analytics with Power BI:

• Power BI Desktop: Install this on your computer. You use it to make and see reports.

• Azure Synapse Analytics workspace: Set this up in the Azure portal. It holds and works with your data.

• Data Lake Storage Gen2: Connect this storage to your Synapse workspace for saving data.

• Synapse workspace URL: Use this to manage and look at your data.

• ETL tools (like Azure Data Factory): Use these to move data into Synapse if you need to.

Note: If you work with finance and operations data, you need a Tier-2 sandbox and must turn on the Delta lake feature in your Synapse Link profile.

Azure Synapse Analytics Integration

Connection Setup

You must make a safe link between Azure Synapse Analytics and Power BI. This is needed before you can make reports. Follow these steps to keep your connection safe and working:

1. Log in to the Azure Portal. Go to your Azure Synapse Analytics Overview page.

2. Look for the Server name link. Open the SQL server's page.

3. Click Show firewall settings to see firewall choices.

4. On the Firewall and virtual networks page, click + Add client IP. This adds your public IP address so you can connect.

5. Set Allow Azure services and resources to access this server to Yes. This lets Power BI and other Azure tools connect.

6. Save your firewall changes.

7. Use the Server name from the Overview page when you connect from Power BI Desktop or other tools.

8. You can test your connection with SQL Server Management Studio (SSMS). Use the server name and your login info.

Tip: Try to use Azure Active Directory authentication. This keeps your data safer.

You need the server name and database name from the Azure portal. Make sure you have your username and password ready. Open Power BI Desktop. Enter the server name and database name. Click Connect. If you have trouble, check your firewall settings. Make sure your IP address is allowed.

Linked Services

Linked services help you connect Azure Synapse Analytics to other tools like Power BI. You set up linked services in Synapse Studio. Here is how you do it:

1. Open Synapse Studio. Go to the Manage section.

2. Under External Connections, pick Linked services.

3. Click + New to make a new linked service.

4. Choose Power BI as the linked service type.

5. Give your linked service a name. Pick your Power BI workspace from the dropdown. If you do not see it, use Edit to enter the workspace ID from the Power BI workspace URL.

6. Click Create to finish.

After you link your Power BI workspace, you can look at datasets. You can also make or change reports inside Synapse Studio. Any changes you make save back to your Power BI workspace.

Note: Make sure your Power BI workspace and Synapse workspace are in the same Azure tenant. This helps you see all your workspaces and keeps things simple.

Here are some best ways to use linked services:

• Always check if you can get into the Power BI workspace.

• Remember, datasets you see in Synapse Studio are read-only. If you want to change them, make new datasets connected to your Synapse data.

• Use 'File > Save As Copy' to send changes to Power BI and keep things in sync.

• Manage permissions in Power BI to control who can see or change reports and datasets.

Data Access in Power BI

Now you can use Power BI to see and use your data from Azure Synapse Analytics. Open Power BI Desktop. Connect to your Synapse SQL pool using the server name and database name. Pick your way to sign in. You can use your work account or a service principal if you want to automate access.

Power BI has two main ways to get data from Azure Synapse Analytics:

• Import Mode puts data into Power BI for fast reports. You must refresh the data to see updates.

• DirectQuery Mode sends live questions to Azure Synapse Analytics. You see real-time data, but some features may not work. Reports may be slower.

To build your report, pick fields from the Fields pane in Power BI. Drag them onto your report to make tables, charts, or other visuals. If you see a credential error, clear the permissions for the serverless SQL endpoint in Power BI's Data source settings. Try again.

Tip: Use role-based access control in Azure Active Directory and Power BI to keep your data safe. Set up row-level security and dynamic data masking if you need to protect sensitive information.

When you finish your report, you can publish it to the Power BI service. This lets others in your group see the newest insights from Azure Synapse Analytics. You can also put Power BI reports into Synapse Studio dashboards for a smooth analytics experience.

Data Modeling

Structuring Data

You should set up your data model to be fast and easy to use. Try using a star schema. This has one main fact table in the middle. It also has smaller dimension tables around it. Star schema is good for Power BI dashboards. It makes questions simple and quick. If you want to save space, you can use a snowflake schema. This breaks dimension tables into smaller parts. But it can make things slower because there are more joins.

For big datasets, split your tables by date or region. This helps Power BI find what it needs faster. Use Azure Data Lake Storage Gen2 to keep your files safe and easy to grow. You can also use external tables. These let you read data from your data lake without moving it.

Tip: Always use the same names and tags. This helps you find and manage your data.

Performance Tips

You want your reports to be fast and work with lots of data. Here are some ways to help:

1. Use clustered columnstore indexes on big tables. These make data smaller and speed up analytics.

2. Spread big tables with hash keys. This puts data in even groups and helps joins go faster.

3. Only load new or changed data with incremental refresh. This saves time and power.

4. Pick the best Power BI mode. Use Import mode for small data. Use DirectQuery for real-time data. Use composite models if you need both.

5. Split tables by time or other filters. This means Power BI looks at less data.

6. Watch your queries in Synapse Studio or Azure Monitor. Find slow ones and fix them.

Security Controls

It is important to keep your data safe. Use role-based access control (RBAC) in Synapse and Power BI. Put users in groups that match their jobs. Only let each group see or do what they need. Set up row-level security in Power BI. This makes sure users only see their own data. You can also hide private columns with dynamic data masking.

Add sensitivity labels to your data in Synapse. These labels move to Power BI and help you share data safely. Use private endpoints and firewall rules to stop unwanted access. Turn on Microsoft Defender for Cloud to watch for threats. Always keep audit logs and check them often.

Note: Good security keeps your reports safe and helps you follow laws like GDPR and HIPAA.
