Transformation of data through etl model

Description:

The image presents a PowerPoint slide illustrating the "Transformation of Data Through ETL Model." This model is a common process in data handling that involves Extracting, Transforming, and Loading data, known as the ETL process.

1. "Extraction," we see multiple databases symbolizing the capture or extraction of important data from various sources. This data is often raw and can consist of numerous formats.

2. "Transform & Load" phase, where there is a "Staging Area." This suggests that data is temporarily held here before it is processed. During this phase, the data may be cleaned, verified, and transformed into a format suitable for analysis.

3. "Transform," indicates further processing or refining of the data. This could involve complex computations, data enrichment, or conversion to conform to the requirements of the target system or analysis tools.

4. "Data Warehouse," where transformed and processed data is stored. The warehouse acts as a centralized repository for data that has been prepared for reporting and analysis.

The consequent result of this ETL process is shown in the "Analytics" component, where a laptop displays a graph that denotes the analysis of the data, which is now ready to yield insights driven by business intelligence practices.
