Microsoft Fabric Connections Demystified

Managing data connections in Microsoft Fabric can be challenging if you’re unsure where to start. This blog post and its detailed YouTube video will help you find, manage, and share the existing data connections, making your workflow more efficient and streamlined. A meaningful use case for this feature is to reuse the existing connections leading to more controlled connections to the data sources. More on this later in this blog.

Understanding Data Connections in Microsoft Fabric

In Microsoft Fabric, a data connection links the platform to various data sources, whether in the cloud or on-premises. Different items in Microsoft Fabric, such as Data Factory Pipelines, Dataflows, Paginated reports, Semantic Models, KQL databases, and Mirrored Azure SQL databases (currently in preview), create these data connections.

Finding Data Connections

To find data connections in Microsoft Fabric:

  1. Click on Settings at the top right of the page.
  2. Select Manage connections and gateways.
  3. Navigate to the Connections tab.

This tab displays all the connections shared with you or created by you. From here, you can check the status of each connection, remove old connections, and manage them as needed.

Manage connections and gateways in Microsoft Fabric
Manage connections and gateways

This page used to be called Manage Gateways where we could configure and manage on-premises data gateways. I have a very old blog post explaining the gateway setup and configuration in the cloud and on your local server here. While it’s an old post, the topics are still relevant, so check it out if you are interested in the gateway configuration.

Note

As the preceding image shows, the Data page is currently in public Preview, hence, it is subject to change. It is also worthwhile to mention that not all connections are currently accessible via this page such as connections that are natively created by KQL databases within Fabric.

Check Connection Status

To check the connection status, click the status button of each connection. The result shows if the connection is online or offline.

Use Copilot in Power BI Desktop to Create Measures from Numeric Columns

I have been thinking about a mechanism to generate measures from numeric columns on Power BI data models. Of course, we can use Tabular Editor, but it requires some scripting, which is all right. However, the more advanced our requirements get, the more complex the C# script. In real-world development scenarios, it does not make sense to blindly create measures for all numeric columns, such as the key columns used to define relationships between tables, making C# scripting a bit more complex.

In this blog and accompanying YouTube video, I explain using Copilot within Power BI Desktop to create measures from numeric columns. This feature represents a significant advancement in Power BI’s capabilities as of April 2024, enabling data analysts and BI professionals to streamline parts of their data analysis tasks.

Prerequisites

As explained in a previous post here, we first need to enable Copilot on the Fabric Portal. Please note that Copilot in Power BI Desktop requires either Power BI Premium Capacity or AT LEAST an F64 Fabric Capacity. Unfortunately, Copilot is NOT available on PPU, Embedded capacities, Fabric capacities smaller than F64 and Fabric Trial (FT) capacities.

We also need to have the latest version of Power BI Desktop installed on our machine. With that, let’s begin.

YouTube Video

Here is the video on YouTube where I explain the same thing in less than 5 min. But if you are after more details, continue reading.

Introduction to Power BI and Copilot

As Power BI evolves, it incorporates more sophisticated AI-driven capabilities that simplify various aspects of data analytics. The integration of Copilot in Power BI Desktop enhances user interaction with data in many ways. Our focus on this blog is specifically using Copilot to create simple yet crucial measures based on numeric columns that previously required manual effort.

Use Copilot for Measure Creation

Using Copilot is straightforward and demonstrates impressive intelligence in its operational logic. The following steps explain how to do so:

Power BI Governance, What Organisations Need to Know

Power BI Governance Art Built by Bing Image Creator

In recent years, Power BI has become one of the most widely used business intelligence (BI) tools. Power BI is more than just a reporting tool; it is a comprehensive analytical platform that enables users to collaborate on data insights and share them internally and externally. In addition to creating reports and dashboards, Power BI allows users to collaborate and share their work with others. For instance, users can share dashboards with their colleagues, allowing them to view, interact, and engage with the data quickly. However, as more organisations adopt Power BI, it becomes essential to ensure appropriate governance processes, policies, and rules are in place. This blog post explains Power BI governance and why business owners need to be conscious of it.

Power BI governance refers to a set of processes, policies, and standards that organisations put in place to manage and control the use of Power BI. Governance is critical to ensure that the use of Power BI is aligned with the organisation’s objectives and strategy, complies with relevant regulations and standards, and protects sensitive data. Power BI governance encompasses several areas, including security, data management, compliance, and user management. It also involves defining data access, sharing, security, and compliance guidelines within Power BI. This includes defining roles and permissions for users, specifying approved data sources that can be used, and ensuring that the data is accurate, up-to-date, and secure across the organisation. In addition, Power BI governance involves monitoring and auditing the use of Power BI to ensure that it is being used appropriately and in compliance with the organisation’s policies. Lack of Power BI governance can impact businesses in various negative ways, so it is important that everyone within the organisation, especially the managerial teams, has a good understanding of how they can benefit from supporting the establishment of Power BI governance across the organisation. Here are some reasons:

  • Better decision-making
    With Power BI governance in place, organisations can ensure that the data used in decision-making is accurate, consistent, and trustworthy. This can help them make informed decisions based on reliable data insights.
  • Improved security and compliance
    Power BI governance helps to establish security measures to protect sensitive data and ensure compliance with regulations and industry standards. This helps to avoid costly data breaches and non-compliance penalties.
  • Efficient use of resources
    By establishing guidelines for roles and responsibilities, data access, sharing, and storage, Power BI governance can help organisations use their resources more efficiently. This can result in cost savings and improved productivity.
  • Enhanced collaboration
    Having Power BI governance policies help business owners to promote collaboration and communication among team members. This can result in improved teamwork and better outcomes for the organisation.
  • Better management and control
    Power BI governance helps organisations to manage and control the use of Power BI within the organisation. This can help them ensure that the tool is being used effectively and efficiently and that data is being used in a way that aligns with their business objectives.

Slowly Changing Dimension (SCD) in Power BI, Part 1, Introduction to SCD

Slowly changing dimension (SCD) is a data warehousing concept coined by the amazing Ralph Kimball. The SCD concept deals with moving a specific set of data from one state to another. Imagine a human resources (HR) system having an Employee table. As the following image shows, Stephen Jiang is a Sales Manager having ten sales representatives in his team:

SCD in Power BI, Stephen Jiang is the sales manager of a team of 10 sales representatives
Image 1: Stephen Jiang is the sales manager of a team of 10 sales representatives

Today, Stephen Jiang got his promotion to the Vice President of Sales role, so his team has grown in size from 10 to 17. Stephen is the same person, but his role is now changed, as shown in the following image:

SCD in Power BI, Stephen's team after he was promoted to Vice President of Sales
Image 2: Stephen’s team after he was promoted to Vice President of Sales

Another example is when a customer’s address changes in a sales system. Again, the customer is the same, but their address is now different. From a data warehousing standpoint, we have different options to deal with the data depending on the business requirements, leading us to different types of SDCs. It is crucial to note that the data changes in the transactional source systems (in our examples, the HR system or a sales system). We move and transform the data from the transactional systems via ETL (Extract, Transform, and Load) processes and land it in a data warehouse, where the SCD concept kicks in. SCD is about how changes in the source systems reflect the data in the data warehouse. These kinds of changes in the source system do not happen very often hence the term slowly changing. Many SCD types have been developed over the years, which is out of the scope of this post, but for your reference, we cover the first three types as follows.

SCD type zero (SCD 0)

With this type of SCD, we ignore all changes in a dimension. So, when a person’s residential address changes in the source system (an HR system, in our example), we do not change the landing dimension in our data warehouse. In other words, we ignore the changes within the data source. SCD 0 is also referred to as fixed dimensions.
