How BI Tools Perform Data Extraction, Transformation, and Loading into a Data Warehouse?

Business Intelligence (BI) tools are critical in extracting, transforming, and loading data from diverse sources into a data warehouse. This Extract, Transform, Load (ETL) process is essential for preparing data for in-depth analysis and subsequent use in operations that uncover valuable insights and provide inputs for informed decision-making.

Let’s discuss the three steps in the ETL process to understand how these steps combine to support BI and data warehousing processes. 

Step # 1: Extract (E)

The first step in the ETL process involves extracting data from multiple sources, including databases, spreadsheets, cloud applications, web services, public information sources, and social media platforms.

BI tools use connectors and adapters to access and connect to various data sources directly or through APIs. BI tools retrieve the required data in its raw form, pulling information from structured and unstructured sources through these connections.

Step # 2: Transform (T)

Upon extracting the data, the next step is transformation. This stage focuses on cleaning, standardizing, and structuring the data to ensure consistency and uniformity within the data warehouse.

BI tools provide a range of data manipulation capabilities to achieve this standardized form, including:

Data Cleansing

This set of processes identifies and resolves errors, missing values, and inconsistencies in the data.

Data Validation

Validation processes ensure the data meets predefined criteria and business rules.

Data Normalization

This process converts data into a consistent format so that all data manipulation processes can have consistent inputs for smoother operations.

Data Enrichment

This set of processes further enhances the data in the warehouse so that data operations deliver better results as the system fills in the missing values and removes inconsistencies.

By applying these transformation operations, BI tools ensure that the data gets more and more optimal for analysis and reporting, eliminating data quality issues that could hinder accurate insights.

Step # 3: Load (L)

Once the data is transformed, the final step is to load it into the data warehouse. The data warehouse serves as a centralized repository where data from various sources is stored in a structured and organized manner. BI tools can load the cleaned data into the data warehouse in the following configurations.

Full Load

This approach loads all data into the data warehouse from the source systems during the initial setup or at scheduled intervals. This method ensures that the data warehouse is always up-to-date with the latest data. However, the downside is that the loading process can take significant time for large datasets.

Incremental Load

This method extracts only the changes or new data since the last load and adds it to the data warehouse. Incremental loading reduces processing time and is suitable for frequent updates of data.

Data Analysis After ETL

With data successfully extracted, transformed, and loaded into the data warehouse, BI tools can now perform in-depth analysis using a variety of techniques:

Online Analytical Processing (OLAP)

OLAP allows users to explore multidimensional data. The process uses dynamic slicing, dicing, and pivoting to gain deeper insights.

Data Mining

BI tools can utilize data mining algorithms to discover patterns, trends, and relationships within the data.

Predictive Analytics

BI tools can predict future trends and outcomes based on historical data.

These tools also ensure that data is efficiently prepared and structured for in-depth analysis by employing a comprehensive ETL process. Businesses use this set of processes to uncover valuable insights, make data-driven decisions, and drive strategic growth.
