Hello! Today we're going to explore the world of cloud data warehouses, specifically Amazon Redshift and Google BigQuery. If you're curious about how companies store, analyze and manage massive amounts of data in today's data-driven world then the answer lies in Cloud data warehouses like Amazon Redshift and Google BigQuery.
In this article, we'll first take a quick look at what a data warehouse is and what its characteristics are, and then do a comparative analysis of Redshift and BigQuery, two leading cloud data warehouse solutions. Let's get started!

What is a Data Warehouse?
The importance of data today
People and machines produce vast amounts of data every day. It enables businesses, governments, and individuals to make informed choices and discover new insights. The importance of data is only growing as our reliance on technology increases, and data has become a key part of modern life. Understanding and utilizing data can help you make better decisions, increase efficiency, and make the most of the opportunities it presents.
Data Warehouse and Cloud Data Warehouse
Data warehouse is a portmanteau of the words Data and warehouse and refers to a structured and integrated environment of technology that aims to accumulate and integrate data in a time series to support efficient decision-making from a strategic perspective. In other words, it is a database that integrates, coordinates, and manages data from each of the distributed databases within an organization and converts them into a common format for efficient decision-making.
Cloud data warehouse is a centralized, large-scale storage solution that enables organizations to store and analyze vast amounts of data in the cloud, making it easy to access and secure. Cloud data warehouses reduce an organization's infrastructure costs, increase flexibility, and are easily scalable.
Here's an analogy to help you understand.
If you think of books as data, you can think of your bookshelf, the place where you store and organize your books, as a "data warehouse" for your books. Let's say you want to share this collection of books with your friends and want them to be able to access your books anytime, anywhere. To do this, you decide to move your entire book collection to an online platform like an e-library. This is similar to a cloud data warehouse, where the data(in this case, books) is stored on the internet and can be easily accessed from anywhere.
So, a cloud data warehouse is like an online bookshelf where all your data(books) are stored and organized for easy access, analysis, and sharing with others. Just like you can easily search for the book you want in an online library, a cloud data warehouse allows you to quickly search and analyze large amounts of data to find useful information and insights.
Features or Data Warehouse
Features | 설명 |
Subject Oriented | - Topic-driven rather than task-driven (data is classified and stored according to the organization's work topics) - Data structures that are not tied to a specific business function or application |
Integrated | - Ensure data consistency with data modeling - Ensure data uniformity through enterprise-wide data standardization - Perform a series of transformations to integrate data as it is acquired |
Time Variant | - Data is retained for long periods of time, storing snapshots of values at every moment in time to enable analysis and prediction of past and present trends. - Necessary for trend analysis of work changes or development over a period of time |
Non-volatile | - After initial data load, no data refresh process exists - There is only data loading and data access - Even if data changes occur, they are reflected in the form of a snapshot without updating the change requirements |
Benefits of Cloud Data Warehouse
1. Scalability
Cloud data warehouses are elastic, so they can seamlessly scale up or down as your business needs change.
2. Flexibility
Cloud data warehouses support a variety of data types, including structured, semi-structured, and unstructured data, and make it easy for businesses to integrate data from different sources.
3. Agility
Cloud data warehouses can quickly process and analyze large amounts of data in near real time. This enables faster, more agile decision-making by providing the insights you need to make informed decisions.
4. Cost Optimization
Cloud data warehouses can be more cost-effective than traditional on-premises data warehouses because businesses don't have to invest in expensive hardware, software, and maintenance.
5. Enhanced security
Cloud data warehouses come with advanced security measures to protect your data from unauthorized access and potential data breaches. These include encryption, firewalls, and regular security updates to keep your data safe.
6. Collaboration
Cloud data warehouses enable collaboration between teams by allowing multiple users to access and analyze data anytime, anywhere.
