    Power BI - Performance and Accuracy



    Performance

    Power BI is a powerful tool for data analysis and visualization, but it does have some performance limitations, especially when dealing with large datasets.



    Handling Large Datasets

    Power BI can struggle with large volumes of data, leading to slower report generation and dashboard performance. The free and Pro versions have data size and storage restrictions, and even the Premium version can experience performance degradation with exceptionally large data models or complex calculations.



    Query Performance

    Issues can arise with slow queries or report visuals, particularly when using DirectQuery or Live Connection. Tools like the Performance Analyzer and Query Diagnostics in Power BI Desktop can help identify and optimize these bottlenecks.



    Data Model Optimization

    Best practices such as preferring integers over strings, avoiding high precision/cardinality columns, and reducing data precision where possible can significantly improve performance.



    Accuracy

    Power BI offers several features to ensure data accuracy, but there are also some areas where it could be improved.



    Data Quality Management

    Power BI supports data quality management through data cleansing, validation, and standardization. It allows teams to set up specific criteria and run data validation tests to identify inconsistencies or errors, such as missing values or outliers. This helps maintain high-quality data and ensure data integrity.



    Automated Data Entry

    Integrating Power BI with other systems or using data integration tools to automate data entry can reduce errors associated with manual data entry, such as typos and missing values.



    Data Quality Metrics

    Power BI helps track data quality metrics like data completeness, accuracy, and consistency, enabling teams to identify and address issues promptly.



    Limitations and Areas for Improvement

    Despite its strengths, Power BI has several limitations that users should be aware of:



    Customization

    Power BI’s customization options are limited compared to other BI tools like Tableau. Users often find it challenging to apply simple formatting options, such as data tables, legends, or colors, and may need to use DAX or custom visuals to achieve the desired results.



    Data Cleansing

    Power BI does not provide built-in data cleansing solutions, assuming that the data is already cleaned and of high quality. Users may need to use external tools for data cleansing.



    User Interface

    The user interface can be bulky, with elements like the formula help window and side panes obstructing the view. Creating scrolling dashboards is also not a native feature and can be cumbersome.



    Sharing and Collaboration

    Reports and dashboards can only be shared with users within the same email domain or those listed in the Office 365 tenant, which can limit collaboration across different organizations.

    In summary, while Power BI is a powerful tool for data integration and analysis, it has specific performance and accuracy considerations. By optimizing data models, automating data entry, and using built-in data quality tools, users can enhance both performance and accuracy. However, users should be aware of the limitations, particularly around handling large datasets, customization, and data cleansing, to make the most of the tool.

    DAX is a formula language used in Power BI to define custom calculations for calculated columns, measures, and tables. It is essential for creating calculated fields, performing data analysis, and optimizing reports. DAX includes functions like SUM, COUNT, and RANKX, and it is crucial for advanced data modeling and analysis in Power BI.

    What are Filters in Power BI?

    Filters in Power BI allow users to control what data is displayed in the visuals. There are several types of filters, including slicer visuals, page-level filters, report-level filters, and drillthrough filters. Slicer visuals are interactive and easy to use, while the filter pane offers more complex filtering options that can be preset and locked for all users.

    Where is data stored in Power BI?

    Data in Power BI is often stored in the cloud, with Microsoft Azure being the primary cloud service used. Specifically, data can be stored in Azure SQL Database or Azure Blob Storage. Power BI can also use a desktop service for local data storage, but cloud storage is more common for collaborative and scalable solutions.

    What is Row-Level Security in Power BI?

    Row-Level Security (RLS) in Power BI limits the data that a user can view and access based on predefined rules and roles. Users can define these rules and roles in Power BI Desktop and publish them to the Power BI Service to configure RLS. This feature ensures that sensitive data is only accessible to authorized users.

    How do you create visualizations in Power BI?

    To create visualizations in Power BI, you start by loading your data into the platform. Once the data is ready, you can select a visualization type from the “Visualizations” pane and drag and drop the fields from the data model into the appropriate areas (e.g., Values, Axis, Legend). Power BI offers a wide range of visualization options, including bar charts, line charts, pie charts, maps, tables, and matrices. You can also customize the visuals, add filters and slicers, and create calculated measures using DAX.

    What is the difference between Power BI Pro and Power BI Premium?

    Power BI Pro is a user-based license that provides features like report sharing, collaboration, and access to published reports. Power BI Premium, on the other hand, is a capacity-based license that offers additional features such as advanced analytics, larger data models, and higher refresh rates. Premium also includes Power BI Embedded and other advanced capabilities, making it suitable for larger organizations with more complex analytics needs.

    How do you add calculated measures in Power BI?

    To add calculated measures in Power BI, you use DAX (Data Analysis Expressions). You can create new calculated measures by defining DAX formulas in the “Model” view. These measures can perform calculations not available in the original data, such as aggregations, ratios, or other custom calculations. Calculated measures are essential for enhancing the analytical capabilities of your reports.
