This blog has been updated on - February 05, 2024

Maintaining & analyzing dozens of datasets has become so pivotal for companies that they're willing to pay extra for it.  As the role of data storage evolves with the advancements in technology, the persistent demand for data warehousing solutions keeps on surging rapidly. Over 54% of organizations are using data warehouses at present; it's the highest adoption rate of data solutions.

To beat the competition & adapt to the changes in the market, data warehousing can make a huge difference. However, you need a deeper understanding to make the most out of it. If you're new to this, you should read this piece till the end:

  • What is data warehousing? How does it work?

  • What are the benefits of data warehousing?

  • What are the types of data warehousing models?

  • Which industries can take the best advantage of data warehousing?

Getting these questions answered must be a priority if you want to move from traditional data storage systems to cutting-edge data warehouse & business intelligence solutions.

What Is a Data Warehouse? How Does It Work?

The term ‘data warehouses’ was coined by Bill Inmon in 1970. Later, in 1991, the very first product based on data warehouse technology, named Prism, was launched for commercial use. Further, Teradata introduced its first data warehouse product in 1997. The first open-source data warehouse, MySQL was released in 2000.

A data warehouse is a massive repository of data derived from resources dedicated to business decision-making & data engineering.

The real concept of business data warehouses is the storage, management, & interpretation of data. It empowers organizations to make informed business decisions.

Enterprises aspiring to boost their data integration practices must leverage data warehouses to analyze & manage data for actionable business insights.

No wonder indulging in data warehouse concepts is a fruitful strategy to combine & transform huge datasets into a single set of data insights & reports.

How Does a Data Warehouse Work?

A data warehouse stores a company’s data in one place. It helps you access and analyze a large amount of historical data to make smart business decisions. It uses tables and columns to structure huge datasets for easy querying and analysis.

A typical data warehouse contains two major components- A ‘fact table’ for the ‘main data’ and a ‘dimension table’ for ‘reference data.’

For example, a data warehouse used in a mobile app for big data sales and marketing setup will feature a fact table for sales data such as billing details and customer info. Meanwhile, its dimension table will showcase other data, including customer demographics and product details.

 

Architecture of a data warehouse & how does it work

What Is Data Warehousing? Definition & Types

A data warehousing system is a database or repository of data. It uses ETL (extract, transform, & load) tools so that companies can use retrieved data for future analysis.

The idea behind data warehouse implementations goes well with predictive analysis for risk management techniques in a business.

Data warehousing involves simplified visualization of complex data in the form of tables, graphs, charts, and other visual interfaces.

There are five types of data warehousing models to integrate with your business. Let's discuss them at a glance.

Types Of Data Warehousing Models

five types of data warehousing models in a visual representation

Enterprise Data Warehouse (EDW)

This type of enterprise data warehouse is optimized for fast querying and analytical purposes. It retrieves data from distinct resources such as transactional setups, operational systems, and other databases.

An EDW is based on a multi-dimensional data model and is ideally customized for an organization's needs. Deploying the enterprise data warehousing benefits offers decision support and a unified approach to data visualization.

Operational Data Store (ODS)

As the name states, this type of data warehousing model works for the operational needs of an organization. It typically collects and analyzes data in real-time.

When the existing data warehouse systems lack reporting results, the role of ODS comes in. Operational data warehousing helps in the daily activities of a business, such as employee records, Customer Relationship Management, etc.

Data Mart

A smaller version of a data warehouse is a data mart. It's developed for a specific unit, segment, and department operating within a business.

Every section of the organization uses a data mart as a centralized database to store, access, & analyze data. The stored data in a data mart is further migrated to ODS, which later moves it to EDW, i.e., Enterprise Data Warehouse.

Cloud Data Warehouses

When a data warehouse is hosted on a SaaS in cloud computing such as Amazon Web Services (AWS), it brings a barrage of advantages for an organization.

Data warehousing in the cloud results in higher scalability and reduced IT expenses on internal resources. Companies can optimize their databases using cloud-based data warehouses & scale up or down their systems as required.

Big Data Warehouses

This type of data warehouse model embraces the role of big data implementation. It processes a large volume of data, whether it's in unstructured, semi-structured, or structured form.

Big data warehouses use non-relational database frameworks along with a schema-on-read approach to store data.

Benefits Of Data Warehousing

Data warehousing is a core element of enterprise business intelligence practices & it's a result-driven technique for any business indulging in it.

Since you've got your answer to this question of what data warehousing is, it's time to pen down the major benefits of data warehousing for any enterprise.

Accelerated Performance

Modern data warehousing solutions offer super-fast querying and advanced analysis of data in bulk.

It involves indexing, materialized views, and denormalization techniques to boost query performance.

Easy Integration

Data warehouses collect and store data from different sources, including log files, transactional databases, and other external sources.

By integrating multi-dimensional data, businesses can comprehensively view meaningful insights and resolve their queries.

Track Historical Data

It becomes easier to track historical data on a data warehouse & compare them to analyze market changes.

It helps in performance tracking, budgeting, and making future predictions like many business analytics tools do.

Better Data Quality

Leveraging custom data warehousing solutions will give accurate data insights to help you make precise business decisions. This is how data warehouses help in predictive maintenance for a business.

Enhanced User Accessibility

Since data warehouses work as a centralized repository that contains data from many sources, users can access it anytime as needed.

High Data Security

Data warehouses adhere to strong security measures to prevent unauthorized access to sensitive data.

List Of Best Data Warehouse Tools

There are many options to consider when choosing the best data warehouse tools. However, only a few of them are preferred for data warehouse implementation. Here are they:

Amazon Redshift

A brilliant data warehousing tool that uses simple SQL queries with existing business intelligence tools for data analysis.

Amazon Redshift can run complex queries on processes based on super-efficient computing, uniform query optimization, parallel execution, and more. Here are the other features of this data warehousing tool:
