Introduction
Business Intelligence (BI) tools have transformed how companies analyze and visualize data.
Two of the biggest names in this space are Power BI (from Microsoft) and Looker (from Google).
But which one is better? Well, that depends on your use case.
This article will break down:
- How BI tools worked before Power BI & Looker.
- The history and evolution of each tool.
- Their pros, cons, and key differences.
- How they compare in performance, complexity, and alternative BI solutions.
By the end, you’ll have a clear understanding of which BI tool fits your needs.
What Came Before Power BI and Looker?
Before modern BI tools, data analysis was painful.
Traditional BI Methods
- Excel & Spreadsheets → Small-scale analysis, limited automation.
- SQL Queries & Reporting → Developers manually wrote queries for insights.
- Custom Dashboards → Built using Python, R, or JavaScript, requiring engineering effort.
These approaches lacked automation, were hard to scale, and often required manual updates.
Then, self-service BI tools like Power BI and Looker emerged, revolutionizing data visualization and analytics.
The History of Power BI & Looker
Power BI: Microsoft’s Answer to Self-Service BI
- Launched: 2015 by Microsoft.
- Built on Excel’s Power Pivot & SQL Server Analysis Services (SSAS).
- Quickly became the most used BI tool globally.
