About the Book
Whether it’s to adhere to regulations, access markets by meeting specific standards, or devise data analytics and AI strategies, companies today are busy implementing metadata repositories – tools that manage metadata about the data, information, and knowledge within their organizations. Until now, most of these repositories have been implemented in isolation from one another; however, this practice is at the core of the problems with metadata management that many companies face today.
Author Ole Olesen-Bagneux, VP and Chief Evangelist at Actian, demonstrates how to effectively manage metadata repositories by properly coordinating them. That will help you and your organization democratize data and excel at metadata management. Coordination must be facilitated by an entirely new kind of team, the data discovery team, that will increase insights for all key players in enterprise metadata management, from the CIO and CDO to the enterprise and data architects within the company.
What You’ll Learn
Whether you’re modernizing enterprise architecture, building data products, or preparing for AI, metadata is your foundation. In this book, Ole Olesen-Bagneux explains why most enterprise metadata efforts fall short and how to fix them. You’ll learn:
✔️ What metadata repositories are and what they do.
✔️ What data, information, and knowledge should be represented in metadata repositories.
✔️ How these repositories should be managed and coordinated.
✔️ How to make data searchable by setting up a data discovery team.
✔️ How to increase innovation by setting up a functional data marketplace.
✔️ How to make information security and data protection more robust.
✔️ How to solidify compliance on data lineage and retention.
✔️ How to activate real enterprise architecture based on evidence.
✔️ How to get a firmer, deeper understanding of your company’s IT landscape.
“Metadata isn’t just documentation—it’s the structure that makes AI work. At Actian, we believe that without metadata at scale, there’s no data intelligence.”
