In the year 2021, the world's data volume was approximately 80 zettabytes. Studies suggest that by 2025, this amount will nearly double, representing the ongoing trend of data expansion. Effectively utilizing and understanding this vast data is not only advantageous but also essential.Â
To navigate this digitalized era, businesses and institutions are increasingly turning to data visualization and business intelligence tools. They help convert intricate datasets into meaningful insights, enabling informed decision-making based on processed information rather than raw numbers.
Power BI, Microsoft's leading business intelligence and visualization tool, leads the charge in this transformative era. Approximately 84,110 companies around the globe are already harvesting the perks of Microsoft Power BI. This suite of cloud-based applications, software, and connectors excels not only in gathering and contextualizing raw business data but also in transforming it into interactive visual dashboards.
The Evolution of Power BI in Business Intelligence
Historically, BI solutions primarily focused on acquiring diverse data sets and delivering reports to business analysts. However, significant shifts have occurred in BI over the past two decades. Consequently, modern BI tools now offer the benefits of integrating AI and machine learning.Â
Power BI began its journey as Project Crescent, initially available for public download in 2011. In the year 2013, it was renamed Power BI and unveiled by Microsoft in September.
The initial versions were on the Microsoft Excel-based add-ins: Power Query, Power Pivot, and Power View. Over the years, Power BI acquired multiple additional features like question and answers, security options, and enterprise-level data connectivity.
It was released for public access on 24 July 2015, with several versions supporting desktop, web, and mobile phones. After 2015, the time period of its evolution signifies a shift from self-service analytics towards increased automation.
- The latest BI systems are tailored to aid organizations in deriving insights to enhance their operational performance.Â
- Augmented analytics focuses on reducing the reliance on data scientists by automating insight generation processes.Â
- Moreover, leveraging machine learning and advanced analytics techniques has become integral.Â
- Popular BI platforms offer tools facilitating the automated preparation of large datasets, enabling pattern recognition and anomaly detection within big data. Some of these platforms even conduct analytics and generate actionable insights autonomously.
Key Tools Required for Power BI Projects
Power BI offers a wide array of tools and services aimed at crafting dynamic, interactive, and intelligent Business Reports.Â
1. Import/Export .csv files
After following the aforementioned steps, upon uploading the dataset, a window named Query Editor will appear. Within Power BI, the Query Editor serves as a tool to edit or format data files prior to their integration into the Power BI Model. Functioning as an intermediary data container, it allows alterations such as modifying data types or adjusting the storage method by selecting specific rows and columns.
2. Views in Power BI
Power BI features three distinct views that can be accessed and toggled through using the Navigation Pane.
- The Report View:
The Report View within Power BI is a dedicated section where users can generate multiple report pages containing visualizations. It offers a design-centric environment enabling the manipulation of visualizations—moving, copying, pasting, and merging them to craft comprehensive reports. This view facilitates the addition of one or multiple pages to create diverse BI report visualizations.
- Data View:
The Data View within Power BI serves as a dedicated section, enabling users to inspect, explore, and comprehend their data. Unlike the perspective within Power Query Editor, where tables, columns, and data are viewed during the editing process, Data view allows users to observe their data after it has been loaded into the model.
- Relationship View (Model View):
The Model View in Power BI displays a comprehensive layout of all tables, columns, and relationships incorporated within your model. It proves particularly useful when dealing with intricate relationships among multiple tables, providing a clear visual representation of the model's structure and connections.
Various tools and panels in Power-BI
Power BI offers a range of tools and services:
- Modeling Ribbon: This panel allows users to execute multiple functions such as uploading datasets, performing calculations, modifying data types, setting data categories for columns, and inserting visualizations.
- Fields List: Within this list reside the elements of the uploaded dataset. Users can select tables or columns to view in the data grid.
- Navigation Pane: This panel oversees the different views available in Power BI (Report/Data/Model), enabling seamless navigation between them.
- Visualization Pane: Hosting over 30 diverse visualizations, this panel aids in presenting reports in various formats. Users can access additional custom visualizations online to expand their options further.
