Disadvantages of Power BI

Power BI, while a powerful Business Intelligence tool, has several disadvantages that organisations should consider. These are listed below:

Performance Issues

It can experience performance degradation when working with exceptionally large data models or complex calculations. It may face challenges when dealing with very large datasets, leading to slower response times.

The desktop app can be slow, especially when handling large datasets, which can delay report generation. It cannot process more than 20,000-30,000 rows without running into issues for some queries, sometimes timing out during processing.

Data Volume Limitations

It has strict limitations on the amount of data it can handle, particularly in its free and Pro versions.. Its Pro restricts the size of each dataset to 1 GB, which can be a significant bottleneck for organisations that need to work with large datasets.

Although Power BI Premium offers more storage capacity (up to 400 GB per dataset), even that may be insufficient for very large-scale operations. If data is larger than 2GB, extending the free version to the paid version is necessary.

Complex Licensing and Pricing

It has a multi-tiered pricing model with free, Pro, and Premium licenses. The complex licensing and pricing structure can be confusing and potentially expensive for businesses as they scale, particularly when multiple users or advanced features are needed.

Determining the appropriate licensing based on the scale of usage and the number of users can be complex, as costs can quickly add up for larger organisations.

Power BI Architecture

It consists of several key components that work together to facilitate Data Analysis:

• Data Sources: These include various databases (SQL Server, Oracle), cloud services (Azure, Salesforce), and flat files (Excel).
• Power Query: This tool allows users to connect to data sources and perform data transformation tasks such as cleaning and shaping the data before analysis.
• Data Model: The transformed data is stored in a data model where relationships between different datasets can be established for comprehensive analysis.
• Power BI Service: This is the online platform where users can publish reports and dashboards for sharing across teams or organizations.
• Power BI Desktop: A desktop application used for creating reports and dashboards offline before publishing them to the Power BI Service.

Power BI Service

The Power BI Service is a cloud-based platform that enables users to share insights through interactive dashboards and reports. It provides features such as:

• Collaboration Tools: Users can share reports with colleagues or stakeholders easily.
• Content Packs: Pre-built templates that allow users to quickly set up reports based on popular services like Google Analytics or Salesforce.
• Mobile Access: Users can access their reports on mobile devices through the its mobile app.
• Scheduled Data Refreshes: Users can schedule automatic updates for their datasets to ensure they always have the latest information available.

Power BI Dashboard

A Power BI dashboard is a single-page view that provides an overview of key metrics through visualizations such as charts, graphs, and maps. Key features include:

• Real-Time Updates: Dashboards can display real-time data from connected sources.
• Interactive Visuals: Users can click on visuals to drill down into more detailed reports.
• Custom Layouts: Dashboards can be customized according to user preferences with drag-and-drop functionality.
