Data Glossary: Nearly 100 Concepts to Understand the World of Data and Technology

The world of data and technology is full of terms that can seem complex or unfamiliar. From widely used expressions like open data to more technical ones such as Application Programming Interface (API), each word holds important meaning for those who work with information.
To make this universe of terms more accessible, we created the Data Concepts Gallery—a virtual space where we compile and define nearly 100 essential terms related to data and technology. This resource works as an interactive dictionary, designed to offer clear and easy-to-understand definitions.
Curious about algorithms or web development? Interested in learning how art and technology connect? On this page, you can explore and filter terms by category, based on your interests.
Check out the full list and discover the meaning behind many of the concepts that shape the data ecosystem. Knowledge begins with a definition!
The Data Concepts Gallery is not just an educational tool — it’s also a commitment to democratizing access to technical knowledge. By removing language barriers and offering clear, simple explanations, we aim to help more people—regardless of their prior experience—understand and use digital tools in their projects, research, or decision-making processes.
That’s why we’ve created a gallery that is constantly updated with terms relevant to today’s technological landscape and to the wide range of professionals who work with data in one way or another: journalists, economists, developers, analysts, and more.
Drawing from our experience developing data-driven technological solutions, we’ve identified the concepts we most often consult and explain across our projects. We’ve defined and organized them on a page where they can be easily searched and filtered—offering a clear, accessible, and practical reference for anyone looking to understand and apply the language of data in their everyday work.
If you’re part of an organization looking to strengthen its work with data or technology, we invite you to join our 100 Partners Campaign. We’re seeking partners to help transform society through technology. Learn here more about our project portfolio and case studies.
