The Gartner Data & Analytics Summit 2025 in London gathered leaders to explore the evolving landscape of data, analytics, and artificial intelligence. The event highlighted that organizations must build AI initiatives on a foundation of robust data governance, strategic alignment, and a culture prepared for transformation.
Data & Analytics (D&A) leaders need to demonstrate the tangible business value from their D&A and AI initiatives, including the rapidly evolving field of Generative AI (GenAI). As organizations strive to maximize the potential of their data assets, many are turning to innovative solutions like data marketplaces and exchanges. These platforms offer a powerful means […]
The world of data management is undergoing a transformation. While some traditional methods had limitations, the concept of data mesh is paving the way for a more effective approach. In this article, we dive into the concept of data products, a important element of the data mesh approach and we explore its key characteristics.What are […]
Artificial Intelligence (AI) has become a transformative force across industries, offering significant benefits such as increased efficiency, personalized services, and better decision-making. However, the adoption of AI also raises ethical, legal, and social concerns, necessitating effective governance mechanisms. AI governance involves establishing policies, regulations, and best practices to ensure the responsible development, deployment, and use […]
Data Governance as the Foundation for Data Democratization. The data governance solution market has evolved from an emerging space to a mature one, with core capabilities including data catalogs, policy management, and privacy and compliance modules. The focus now is on elevating data governance to a strategic capability, enabling organizations to move to a federated […]
Data Virtualization is definitely on the rise. At its Data and Analytics Summit in London, Gartner was projecting accelerated data virtualization adoption for both first-time and expanded deployments. Besides market analysts, we also see high demand and can confirm this being one of the hottest data solutions. But what are the top uses cases for data virtualization?Â
