Calculated columns are added row by row and stored in the data model, usable in visuals or further calculations. Measures are dynamic calculations computed at query time, often aggregating data. Measures are generally more efficient for large datasets and interactive reporting.

5. What is row-level security (RLS) and how can it be implemented in Power BI?

Ans:

RLS (Row-Level Security) restricts data access so users see only what they are authorized to view. It is implemented by defining roles and applying table-level filters in Power BI Desktop, then assigning users to these roles via Power BI Service to enforce role-specific data access.

6. What methods are available to improve Power BI report performance?

Ans:

To enhance performance, reduce the data model by removing unnecessary columns and tables, simplify complex DAX formulas, use aggregations, limit visuals per page, and enable query folding in Power Query. These practices help reports load faster and run efficiently.

7. What types of filters does Power BI offer for report customization?

Ans:

A variety of filters are available in Power BI to manage the visibility of data in reports. Visual-level filters affect a single visual, page-level filters apply to all visuals on a page and report-level filters impact the entire report. Additionally, slicers provide interactive filtering options that allow users to dynamically select data subsets while viewing reports.

8. What is the purpose of a Power BI Gateway?

Ans:

A Power BI Gateway acts as a safe link between cloud-based Power BI services and on-premises data sources. It enables scheduled or live data refreshes by allowing Power BI to access data stored inside an organization’s local network without moving it to the cloud, ensuring that reports and dashboards display up-to-date information.

9. How is data refresh managed within Power BI?

Ans:

Data refresh in Power BI ensures that datasets stay current by updating data from source systems. Users can schedule automatic refreshes in the Power BI Service and for on-premises data sources, a configured gateway facilitates this process. There are different refresh types, such as full refresh, which reloads all data and incremental refresh, which updates only new or changed data.

10. Can you explain the differences between Import, DirectQuery and Live Connection modes in Power BI?

Ans:

Power BI offers three main connection modes: Import, DirectQuery and Live Connection. Import mode loads data into Power BI for fast querying but requires refreshes to update data. DirectQuery queries the data source live each time, providing real-time data but with potential latency. Live Connection connects directly to Analysis Services models, allowing live data interaction without importing it into Power BI.

1. What exactly is Power BI and why is it important for business intelligence?

Ans:

Power BI is a powerful data visualization and business analytics tool created by Microsoft that helps organizations turn raw data into interactive reports and dashboards. Because it makes it simple to collect data from various sources, analyze it fast and disseminate insights to facilitate improved decision making, it is frequently used in business intelligence. With its user friendly interface and strong integration with other Microsoft tools, Power BI enables businesses to understand trends, monitor performance and uncover new opportunities.

2. How do you connect Power BI to different kinds of data sources?

Ans:

Numerous data sources, including databases, Excel files, cloud services and even online APIs, can be accessed with Power BI. Using the Get Data option in Power BI Desktop, you simply select the source type, provide necessary credentials and establish the connection. Once connected, you can import the data into Power BI for analysis or use live connections depending on your needs, making it flexible for many scenarios.

3. What is the difference between Power Query and DAX in Power BI?

Ans:

Power Query and DAX serve different purposes in Power BI. Power Query is used to extract, clean and transform data before it enters the data model it’s essentially the “data preparation” stage. On the other hand, DAX is a formula language used within the data model to perform calculations and create dynamic aggregations after the data is loaded. So, Power Query shapes your data upfront, while DAX helps analyze and calculate insights within the reports.

4. What are Power BI's computed columns and measures and when are they appropriate to use?

Ans:

Calculated columns add new data fields to your tables by applying row-by-row calculations, which are stored in the model and useful for creating additional data points. Measures, however, are calculations performed on-demand during report interaction, often used for summaries like totals or averages. You use calculated columns when you need static data per row and measures when you want dynamic aggregations that respond to user filters and selections.

5. How do you set up row-level security (RLS) in Power BI to control data access?

Ans:

Depending on their jobs, row-level security (RLS) limits the data that users can view. To implement RLS define security roles and set filter conditions on tables inside Power BI Desktop. After publishing your report to Power BI Service, assign users or groups to these roles. This setup guarantees that each user only views data they are authorized to see, providing secure and personalized reporting.

6. What are the different ways data can be refreshed in Power BI?

Ans:

Data refresh in Power BI can be done manually or automatically. Scheduled refreshes allow datasets to update at set intervals, ensuring reports always reflect the latest data. For on-premises data sources, a gateway must be configured to enable refresh. Additionally, there are full refreshes that reload all data and incremental refreshes that only update new or changed data, which helps improve efficiency for large datasets.

7. What techniques are available to enhance Power BI reports' responsiveness and speed?

Ans:

To speed up Power BI reports, you can reduce the size of your data model by removing unnecessary columns and tables. Simplifying complex DAX formulas and using aggregations instead of detailed calculations helps. Limiting the number of visuals on a page and enabling query folding in Power Query, which pushes transformations back to the data source, also improve performance and reduce loading times.

8. What are bookmarks in Power BI and how do they help enhance reports?

Ans:

With Power BI, bookmarks let you record a report page's current state, complete with filters, slicers and images. They are useful for creating interactive storytelling by guiding users through different views or scenarios within a report. Bookmarks can be combined with buttons and navigation to build customized user experiences, making reports more dynamic and engaging.

9. What is the difference between DirectQuery and Import modes in Power BI?

Ans:

Import mode brings data into Power BI’s internal storage, allowing for fast querying and offline work, but requires scheduled refreshes to stay up-to-date. DirectQuery mode, however, leaves data in the source system and queries it live every time a report is used, providing real-time data but sometimes with slower response times. Choosing between them depends on your data size, freshness needs and performance considerations.

10. How do you manage relationships between tables in Power BI?

Ans:

In Power BI, relationships connect tables so you can build a unified data model. You define these relationships by matching columns (keys) in different tables, often using primary and foreign keys. Properly managing relationships ensures data flows correctly in visuals and calculations, supporting accurate analysis. You can set cardinality, cross-filter direction and manage inactive relationships to control how data interacts across your model.

1. What is Power BI and how is it used in business reporting?

Ans:

Microsoft Power BI is an application for data visualization and business intelligence that assists users in transforming unstructured data into dynamic dashboards and reports. It works by allowing the users to connect a various data sources, transform the data as needed and create visualizations for analysis. The platform includes Power BI Desktop for building reports, the Power BI Service (cloud-based) for sharing and collaboration and Power BI Mobile for viewing reports on the go.

2. What is DAX in Power BI and why is it important?

Ans:

DAX, or Data Analysis Expressions, is a formula language used in Power BI for performing calculations and data analysis. It helps users create custom fields like calculated columns, measures and calculated tables. DAX includes a wide range of functions such as aggregations (e.g., SUM, AVERAGE), filters (FILTER, ALL) and logic-based formulas (IF, SWITCH). It is essential for building powerful, dynamic data models.

3. What types of relationships can you create between tables in Power BI?

Ans:

Power BI supports three main types of relationships between tables: one-to-one, one-to-many and many-to-many. In a one-to-one relationship, each row in one table matches exactly one row in another. One row in one database can relate to several rows in another, a phenomenon known as one-to-many relationships. Many-to-many relationships occur when rows in both tables can match multiple entries in the other, often requiring a bridge or intermediary table.

4. How do Import and DirectQuery modes differ in Power BI?

Ans:

In Import mode data is fully loaded into Power BI’s internal storage, allowing for fast performance and offline access. However the data needs to be refreshed to stay up to date. DirectQuery mode doesn’t store data in Power BI; instead, it queries the source live each time you interact with a report. While this allows for real-time data access, it may impact performance depending on the source system's speed.

5. What are KPIs in Power BI and how are they used?

Ans:

Key Performance Indicators (KPIs) in Power BI are visuals used to track the performance of specific business metrics against set goals. A typical KPI displays the actual value (like revenue), the target value (goal) and an indicator showing progress, often using colors like green for above target and red for below. KPIs help businesses quickly assess whether they are meeting their performance objectives.

6. What kinds of data sources are compatible with Power BI?

Ans:

Power BI can connect to a wide variety of data sources. These include traditional databases like SQL Server, Oracle and MySQL; cloud-based services like Azure, Snowflake and Google BigQuery; and file types such as Excel, CSV, JSON and XML. It can also connect to APIs and online platforms like SharePoint and Dynamics 365, making it highly flexible for different data environments.

7. How does Power BI help track performance with KPIs?

Ans:

Power BI helps track key performance indicators by allowing you to compare actual results with target values in a clear and visual way. A KPI visual displays the metric you're tracking, the goal you want to reach and an icon or color showing how you're progressing. This makes it easy to spot trends and understand whether your performance is improving or falling behind.

8. What is Power Query Editor and how is it used in Power BI?

Ans:

Power Query Editor is a tool in Power BI used for connecting to, transforming and cleaning data before its used in reports. It allows users to perform tasks like removing duplicate rows, changing data types, splitting or merging columns and filtering records. Once the data is prepared, its loaded into the Power BI data model for visualization. Power Query simplifies data preparation without needing complex coding.

9. What are hierarchies in Power BI and why are they useful?

Ans:

Hierarchies in Power BI are used to structure data into levels so users can drill down into more detailed information. For example, a Date hierarchy may include Year → Quarter → Month → Day, allowing users to explore trends at different time levels. Similarly, a geographic hierarchy might go from Country → State → City. Hierarchies improve report navigation and enhance user interaction.

10. What are the different data connectivity options available in Power BI?

Ans:

Power BI offers three main data connectivity modes: Import, DirectQuery and Live Connection. Import mode brings data into Power BI for fast performance and offline access. DirectQuery connects to the source in real-time but may be slower. Live Connection is similar to DirectQuery but is used specifically for SQL Server Analysis Services (SSAS) models, allowing live analysis without importing data into Power BI.

1. How is Power BI different from Excel in terms of data analysis?

Ans:

While both Power BI and Excel are used for analyzing data, Power BI is more advanced regarding the creation of graphic reports and interactive dashboards. Unlike Excel, which is spreadsheet-based, Power BI is designed for handling larger datasets, connecting to various sources and providing dynamic, visually rich analytics. Power BI also offers better automation, real-time data refresh and sharing features, making it more suitable for modern business intelligence needs.

2. How does Power BI handle data extraction and transformation through Power Query?

Ans:

Power BI uses Power Query as its ETL (Extract, Transform, Load) tool to prepare data before building reports. First it connects to a data source (extract), then allows users to clean, filter, merge, split or reshape data (transform) using a user-friendly interface. Once the data is ready, its loaded into the Power BI data model (load). This process ensures data is clean, structured and optimized for analysis.

3. What is DAX in Power BI and what are some commonly used functions?

Ans:

In Power BI, unique calculations like measures and calculated columns are created using the mathematical language known as DAX (Data Analysis Expressions). It works similarly to Excel formulas but is more powerful for building dynamic data models. Commonly used DAX functions include SUM() for totals, AVERAGE() for mean values, CALCULATE() for advanced filters and IF() for conditional logic. DAX helps bring intelligence and flexibility to reports.

4. How are relationships between tables set up in Power BI?

Ans:

In Power BI, relationships connect different tables so you can build a unified data model. These relationships are defined by linking common fields, like an ID or code shared between tables. Power BI supports one-to-one, one-to-many and many-to-many relationships. Once relationships are created, you can pull data from multiple tables into a single report without manually combining them, ensuring consistency and accuracy in your analysis.

5. What is the main difference between Import and DirectQuery modes in Power BI?

Ans:

Import mode loads the data directly into Power BI, allowing fast performance and offline access, but it needs to be refreshed periodically. DirectQuery, on the other hand, doesn't import the data it connects live to the data source and fetches data in real-time whenever the report is used. Import is faster for most use cases, while DirectQuery is suitable when working with large, constantly updated datasets.

6. How do you add and use slicers in Power BI reports?

Ans:

Slicers in Power BI are interactive filters that let users control which data is displayed in visuals. To add a slicer, you simply drag a field (like "Region" or "Category") into a slicer visual. Once added, users can click on the options to filter the entire report accordingly. Slicers make it easier for viewers to explore the data themselves without changing the actual report layout.

7. What is row-level security in Power BI and how do you use it?

Ans:

Row-level security (RLS) in Power BI is a feature that restricts data access for users based on their role or identity. It ensures that each user only sees the data relevant to them. You implement RLS by creating roles and defining rules (like filtering data by region or department) in Power BI Desktop. After publishing the report, you assign users to those roles in the Power BI Service.

8. What can you do if your Power BI reports are running slowly?

Ans:

If Power BI reports are slow, several steps can improve performance. You can reduce the size of the data model by removing unnecessary columns or tables, simplify DAX calculations and limit visuals on each report page. Enabling query folding in Power Query and using aggregations or summary tables can also help. It's important to monitor performance using the Performance Analyzer tool in Power BI Desktop.

9. How do you publish and share Power BI reports with others?

Ans:

To share a Power BI report, first publish it from Power BI Desktop to the Power BI Service (cloud platform). From there, you can share the report directly with stakeholders by giving them access or adding it to a shared workspace. You can also embed reports in Microsoft Teams, SharePoint, or even set up automatic email subscriptions, allowing easy access for team members and decision-makers.

10. What does Power BI Service offer and how is it different from Power BI Desktop?

Ans:

Power BI Service is a cloud-based platform used for hosting, sharing and collaborating on reports created in Power BI Desktop. While Power BI Desktop is used for building and designing reports locally, the Service is used to publish those reports, set up scheduled data refreshes, manage user access and view dashboards from anywhere. Essentially, Desktop is for development, while the Service is for distribution and collaboration.

1. What is Power BI and what are the key parts that make it work?

Ans:

Microsoft created Power BI, a business intelligence application that enables users to model and transform data, connect to data sources and produce interactive dashboards and reports. Its core components include Power BI Desktop (used for building and designing reports), Power BI Service (a cloud-based platform for publishing, sharing and collaboration) and Power BI Mobile (for viewing reports on smartphones and tablets).

2. How is Power Query used to clean and transform data in Power BI?

Ans:

Power Query is Power BI’s built-in tool for transforming raw data into structured format suitable for analysis. It lets users connect to different sources and apply transformations like filtering rows, removing duplicates, changing data types, splitting columns and merging tables all without writing code.

3. What is DAX in Power BI and how is SUM different from SUMX?

Ans:

DAX (Data Analysis Expressions) is the formula language used in Power BI to perform custom calculations on your data. It is used for creating measures, calculated columns and calculated tables. SUM() is a basic DAX function that adds up all the values in a single column.

4. What does a data model mean in Power BI and why is it important?

Ans:

A data model in Power BI is the structured representation of your data, including tables, relationships, calculations and metadata. It brings together data from different sources and allows you to organize and analyze it in a connected way.

5. How do you define relationships between tables in Power BI?

Ans:

In Power BI, relationships are used to connect different tables based on common fields such as IDs or keys. You can create these relationships manually or let Power BI detect them automatically. Most commonly, relationships are one-to-many, meaning one record in a table (like "Customer") is linked to many records in another (like "Sales").

6. What are calculated columns in Power BI and how are they not the same as measures?

Ans:

New columns are added to a table using DAX expressions and assessed row-by-row are known as calculated columns. They are stored in the data model and can be used in visuals or for building relationships. Measures, however are dynamic calculations that are only evaluated when you use them in a visual and they summarize or aggregate data.

7. How is Power BI Service different from Power BI Desktop and what is each used for?

Ans:

Power BI Desktop is the tool used on your computer to build and design reports by connecting to data, transforming it and creating visuals. Power BI Service is the online platform where you publish those reports to share them with others, set up data refresh schedules, manage acces and collaborate in workspaces.

8. How can you restrict users from seeing certain data in Power BI?

Ans:

To control what users can see, Power BI offers a feature called Row-Level Security (RLS). With RLS, you define roles and apply filters to your data model so that users in certain role only see data relevant to them for example, a regional manager only seeing sales from their region.

9. What is the difference between DirectQuery and Import mode and when would you use each?

Ans:

In Import mode data is brought into Power BI and stored in the report file, which allows for fast performance but requires scheduled refreshes to stay current. DirectQuery leaves the data in the original source and queries it live every time the report is used, which is better for large or frequently updated data but can be slower.

10. Can you describe a time you built a complex dashboard and solved performance issues?

Ans:

In a project where I built a dashboard with multiple data sources and visuals showing sales, inventory and customer metrics, the report began to lag due to the large volume of data and complex DAX calculations. To improve performance, reduced the number of visuals on each page, optimized the data model by removing unused columns, replaced calculated columns with measures where appropriate and used summary tables with pre-aggregated data.
