Data is the core aspect of any organization for effective and strategic decision-making. However, the surge in a colossal amount of data has led to data silos because organizations often rely on experts like Data Analytics and Data Scientists to gain insights and share them with decision-makers. Such dependence on experts slackens the decision-making process and results in productivity loss. To mitigate such issues, organizations can embrace the combined power of Data Warehouses and Business Intelligence tools. Since data is organized in Data Warehouses and Business Intelligence tools like Tableau can be used by non-experts, it expedites collaboration and decision-making processes. 

In this article, you will learn how to connect a Tableau Data Warehouse and understand the value of BI and Data warehousing.


Basic understanding of analytics.

What are Data Warehouses?

The term ‘Data Warehousing’ was coined by IBM researchers Barry Devlin and Paul Murphy in the late 1980s. The purpose of the data warehousing approach was to build an architectural model for moving data from operational systems to decision environments. Data Warehouse is a Data Management system that enables and supports Business Intelligence (BI), particularly analytics operations. 

Data Warehouses provide organizations with the broad and unique benefit of allowing them to analyze massive volumes of data. 

The four unique characteristics of Data warehouses are:

  • Integrated: Data Warehouses bring together different types of data from various sources to establish consistency.
  • Subject-Oriented: Data Warehouses are capable of supporting the analysis of data pertaining to a functional area.
  • Time-Variant: Data Warehouse helps you in examining the changes over time.
  • Non-Volatile: The data that enters the Data Warehouse remains non-volatile.

Various Data Warehouses

1) Oracle

Oracle Database was the first database designed with corporate grid computing in mind. It is one of the most adaptable and cost-effective data and application management systems available. Oracle is a high-performance Data Warehouse that can be used for Analytics and Machine Learning purposes. This Data Warehouse is extremely secure and features a robust multi-tenant architecture.

2) Amazon Web Services – Redshift

Amazon Web Services – Redshift is a Cloud-based, fully-managed Data Warehouse that enables users to connect with a variety of data sources and BI tools. It provides both serverless (preview) and provisioned services, allowing users to conduct analytics without worrying about managing the Data Warehouse. 

3) BigQuery

BigQuery is a multi-cloud, serverless and highly scalable Data Warehouse specifically built for business agility. Using BigQuery, you can get real-time updates on different types of business operations. BigQuery also comes along with built-in tools like Machine Learning, Geospatial Analysis, and Business Intelligence to enable users to efficiently manage and analyze the data.

4) Snowflake 

Snowflake is a popular Cloud Data Warehouse built on top of AWS or Azure and Googe cloud architecture. It is known for its ability to accommodate multi-cloud architecture configurations. Snowflake also helps with Data Integration, Business Intelligence, Security, and Advanced Analytics. Snowflake’s architecture is what sets it apart from other Data Warehouses. The architecture is designed to allow independent scaling of storage and computation.

What is Tableau?

Stanford researchers Pat Hanrahan, Christian Chabot, and Chris Stolte founded Tableau in January 2003. Tableau was acquired by Salesforce later in 2019. The headquarters of the corporation is now in Seattle, Washington.

Today, Tableau is known as one of the popular Interactive Data Visualization platforms that mainly focuses on Business Intelligence (BI). Tableau allows for complex computations, Data Blending, and Dashboarding in order to create appealing visualizations.

Tableau aids in the simplification of raw data into a format that is simple to comprehend. With Tableau, Data Analysis can be performed faster, and the visualizations can be generated in the form of Worksheets and Dashboards.

Understanding the value of Business Intelligence (BI) & Warehousing

Now, let us understand what Business Intelligence is and what is the value of BI and Warehousing together in organizations today.

What is Business Intelligence?

Business Intelligence (BI) dates back to the 1800s, when financial counselors exploited market knowledge that their competitors lacked to gain an advantage. It was in 1989 when Howard Dresner, a former Gartner analyst, coined the term Business Intelligence. BI refers to a group of intelligent systems that collect, organize, analyze, and display proprietary data to enable users to derive business insights. 

Importance of BI

The goal of Business Intelligence is to use relevant data to improve a company’s operations. Organizations that use BI tools can turn their acquired data into useful information about their organizational operations and plans. Such information can then be utilized to make better decisions that boost productivity and revenue, resulting in faster growth and profitability.

What is the value of Business Intelligence and Warehousing together?

Business Intelligence is a collection of Applications, Tools, and infrastructure that enables organizations or users to optimize their Business Decisions and Performance. And a Data Warehouse is the storage and organization of that data to support BI operations. Today, maintaining and deploying a Data Warehouse is so crucial to BI that it is commonly referred to as BIDW. BIDW has been helping organizations in more than one aspect. Some of them are explained below.

1) Performance Metrics

Metrics are used to evaluate the activities and behavior of a business, as well as its overall performance. Additionally, Performance Metrics define a range of the data that can be used to construct, confirm, or refute a hypothesis based on previously established business objectives. 

2) Democratize Data

Data Democratization is based on the self-service approach, which enables everyone in the organization to have easy access to the data. This approach allows users to utilize desired data without the need for permission from administrators. Democratizing the data using BIDW provides users the flexibility to instantly access and comprehend data, resulting in faster decision-making. 

3) Data Storytelling

Translating Data Analysis into layman’s words in order to influence a strategic business decision is known as Data Storytelling. The right warehouse for the data and Business Intelligence tools makes it quicker to collect data, compile information, and share stories.

4) Data Mining

Data Mining, also known as knowledge discovery, is a method of extracting useable data from a larger quantity of raw data. This method aids in the discovery of trends, themes, and patterns in enormous volumes of data. In BI, data mining techniques are frequently employed to categorize, group, predict and correlate different aspects of businesses.
