12 Apr 2023 | AgileData DataOps, Blog, What is


AgileData mission is to reduce the complexity of managing data.

In the modern data world there are many capability categories, each with their own specialised terms, technologies and three letter acronyms, We want managing data to be simply magical, so we share articles that explain these terms as simply as we know how.

In this article we describe what technology is required to build a Data Warehouse.

The key components of a successful data warehouse include data sources, data integration, data storage, metadata, data marts, data query and reporting tools, data warehouse management, and data security. Each component plays a crucial role in empowering data magicians like business and data analysts to efficiently manage, analyse, and secure their data, leading to valuable insights and informed decision-making.


Greetings, data magicians!

As experts in the realm of business and data analysis, you’re well aware that data warehouses are a powerful tool for making sense of vast amounts of information. But have you ever wondered what magical technology components lie at the heart of a successful data warehouse?

Let’s unveil the essential technological components that every data magician leverages when using a high-performing data warehouse.

Data Sources: The Wellspring of Information

The journey of a data warehouse begins with data sources.

These are the origins of your raw data, which can include transactional databases, spreadsheets, log files, and even social media feeds. Data magicians must tap into these rich sources to gather the information needed for their analytical spells.

Data Integration: The Art of Harmonisation

With data gathered from a multitude of sources, the next step is to weave it all together in a harmonious tapestry.

Data integration involves cleaning, transforming, and loading the data into the Data Lake or Cloud Analytics Database. Data magicians must ensure the data is consistent, accurate, and ready for analysis, turning the cacophony of disparate data into a harmonious symphony.

Data Storage: The Library of Knowledge

Once the data is integrated, it’s time to store it in the Data Lake or Cloud Analytics Database.

A high-quality storage solution is vital for maintaining the integrity and accessibility of your data. Modern data stacks often rely on cloud storage platforms, which provide scalable, cost-effective, and secure options for data magicians. So, whether you need to store a few scrolls or an entire library of magical tomes, a reliable data storage solution is essential.

Metadata: The Guide to Your Data Universe

As a data magician, you know that understanding your data is vital for successful analysis.

That’s where metadata comes in. Metadata is the information that describes the data stored in your warehouse. It’s like the map that guides you through the vast landscape of your data universe. A comprehensive metadata management system helps data magicians keep track of their data and ensures they always know what’s where in their data warehouse.

Consumable Data: The Focused Chambers of Insight

Consumable data is smaller, specialised sets of data within a data warehouse.

They’re designed to focus on specific subjects, business units or a set of core business processes, such as sales or marketing, or order to delivery, to make it easier for data magicians to conjure up insights relevant to their domain. Consumable Data is like the focused chambers in your magical lair, where you can hone your analytical prowess without getting lost in the vastness of the data warehouse.

Data Query and Reporting: The Magic Mirror of Discovery

Once your data is integrated, stored, and organised, it’s time to cast your analytical spells.

Data query and reporting tools enable data magicians to extract, manipulate, and present the data stored in their warehouse. These tools are like the magic mirror that reveals hidden insights and allows you to share your discoveries with others. From simple data visualisation to complex predictive analytics, data query and reporting tools empower data magicians to unleash the full potential of their data warehouse.

Data Warehouse Management: The Enchanted Guardian

A data warehouse is a living, breathing entity that requires care and attention.

Data warehouse management tools help data magicians maintain, monitor, and optimise their data warehouse. These tools are like the enchanted guardians that watch over your data warehouse, ensuring it remains healthy and efficient. From monitoring performance to managing security and access, data warehouse management tools are indispensable for any data magician.

Data Security: The Magical Shield of Protection

Last, but certainly not least, is the all-important issue of data security.

As data magicians, you understand that the information stored in your data warehouse is a treasure trove of insights that must be protected from prying eyes and malicious intent. Data security involves implementing encryption, access control, and monitoring systems to safeguard your data warehouse. It’s like casting a powerful magical shield around your precious data, ensuring only authorised data magicians can access it and keeping it safe from harm.

The essential technological components of a successful data warehouse are much like the magical ingredients needed for a powerful potion. From data sources and integration to storage and security, each component plays a vital role in empowering data magicians to conjure up valuable insights and make informed decisions. By mastering these components and selecting the right tools and solutions, you’ll be well on your way to creating a data warehouse that’s truly magical.

So, gather your ingredients, hone your spells, and embark on the enchanting journey of data warehousing.

Data Warehouse vs Data Warehouse Technology vs Cloud Analytics Database

A Data Warehouse, as defined by Bill Inmon, is a subject-oriented, integrated, time-variant, and non-volatile collection of data that supports decision-making processes.

Data Warehouse Technology refers to the software, hardware, and tools used to build, manage, and maintain a data warehouse. This includes elements such as data integration tools, data storage systems, metadata management systems, and query and reporting tools. .

Cloud Analytics Databases, on the other hand, are database management systems specifically designed for analytical processing and hosted on cloud computing platforms. They offer features such as flexibility, scalability, high performance, cost-effectiveness, and collaboration, making them an attractive choice for handling large-scale analytics tasks. 

Keep making data simply magical provides the technology capabilities required for a data warehouse within the AgileData product, all without you having to do a thing.

The AgileData Product enables you to collect, combine and consume data in a simply magical way.
