Analysis and Visualisation of Data with PowerBI and Tableau


  • A computer and internet access required


Organizations can use business intelligence (BI) to analyse historical and current data, which enables them to make quick and informed decisions.

Tools for business intelligence make this possible by combining data from multiple sources and presenting findings in visual formats that are easy to understand and share.

The purpose of business intelligence systems is to gain strategic, tactical, and operational insights by integrating data gathering, data storage, and knowledge management with data analysis. This allows the organization to transform all kinds of data into meaningful information for decision-making and insight.

Businesses use business intelligence systems to collect, analyze, display, and share information both internally and externally. These environments are composed of a variety of technologies, applications, processes, strategies, products, and technical architectures.

How business intelligence works

The four key steps business intelligence follows to turn raw data into meaningful insights for everyone in the organization are: 1. Data cleansing 2. Data analysis 3. Data visualization The first three steps — data collection, analysis, and visualization — lay the groundwork for the final step — decision making. Businesses had to manually analyze data before BI was available, but the tools automated many of the processes and saved businesses time and money.

Step 1: Collect and transform data from multiple sources

Extract, transform, and load (ETL) is the methodology that business intelligence tools use to combine structured and unstructured data from different sources. In the next step, the data is transformed and then restructured and stored in a central location where applications can easily query and analyse it as one comprehensive data set.

Step 2: Uncover trends and inconsistencies

When data mining, or data discovery, is done with automation, patterns and outliers are quickly discovered that provide an understanding of the current state of a business. There are many kinds of analytical tools available with BI solutions, including exploratory, descriptive, statistical, and predictive types that allow further exploration of data, the prediction of trends, and the generation of recommendations.

Step 3: Use data visualization to present findings

Data visualizations are used in business intelligence reporting to enhance understanding and sharing of findings. A variety of reporting methods, such as interactive data dashboards, charts, graphs, and maps, enable users to see what is currently happening within the organization.

Step 4: Take action on insights in real time

Companies can move quickly from insights to action by viewing current and historical data in context with business activities. By utilizing business intelligence, you can adjust in real time and make long-term changes that eliminate inefficiencies, adapt to market shifts, fix supply problems, and resolve customer issues.
