The Enterprise Data Catalog

Sune S 08/07/2024

So, what is a data catalog? Is it just another data tool for the data geeks? Nope. The data catalog is the foundation for data democratization within an organization. It addresses core structural issues in data that affect how we discover and access information. It addresses issues such as data organization, metadata quality, and ecosystem interactions. By addressing these fundamental challenges, we can significantly improve our ability to efficiently find and use relevant data across domains. This is what 'The Enterprise Data Catalog' is all about. Ole Olesen-Bagneux has written a solid and dense book, that is rich in experience, as Ole knows a lot about Information & Library Science with a combination of Data Management and IT. Olesen-Bagneux's book goes to the heart of data cataloging, addressing structural data issues related to data discovery. It's not just a manual, but an integration of information and library science with data management, promoting a holistic view of data and information across multiple disciplines. This multidisciplinary approach emphasizes the need to search and find data regardless of its structure, format, or medium. The book is a versatile resource for anyone in the world of data. It helps in planning a data catalog implementation, offering insights on foundational considerations, the purposes of what data cataloging really is, and what is required to create a functional data catalog. Olesen-Bagneux also provides a deep understanding of search mechanisms, differentiating between searching for data and searching in data, which enhances the data discovery processes. It provides guidance on how to articulate data catalog value to stakeholders, identify key stakeholders, and integrate data catalogs into system environments. It also explores how data catalogs support data lifecycle management, emphasizing the importance of time and the interconnectedness of data lifecycles. Olesen-Bagneux presents a clear definition of a data catalog as an organized inventory of an organization's data. He emphasizes its role in providing visibility, organizing data, and enabling search functionality. His academic yet approachable style simplifies complex topics and makes them understandable to anyone. A highlight of the book is the discussion of search, in which Olesen-Bagneux differentiates between "searching for data" and "searching in data" and guides readers through the entire value stream from initial question to discovery. He argues for adopting a librarian's mindset to effectively find relevant data sources. Metadata is another key topic, and Olesen-Bagneux highlights its role in making data searchable, ensuring accessibility, and providing security. The book also addresses the contemporary concept of the data mesh, presenting it as essential for scalable and operational data organizations, and discussing various approaches to data catalogs, including knowledge graph-based methods. The importance of data lifecycle management is often overlooked, but Olesen-Bagneux highlights the complexity of managing data over time and the interaction between different lifecycle stages, and calls for more attention to this critical aspect. Toward the end of the book, Olesen-Bagneux looks to the future of data management, envisioning data catalogs as potential internal search engines within organizations. This visionary perspective serves as a fitting conclusion to the book. In the Afterword, he touches on the ethical implications of data catalogs, reminding the reader of the responsibilities that come with increased data accessibility. This ethical discussion is both timely and essential. 'The Enterprise Data Catalog' is more than a guide to data catalogs. It's a comprehensive exploration of data discovery, access, and organization. It's a must-read for data professionals (and any business professional, for that matter) that seamlessly blends theory and practical advice. I highly recommend this book.

This book has opened my eyes to the seemingly infinite world of possibilities in searching for data. Without super deep prior understanding of data search and data catalogues The Enterprise Data Catalog has opened a world of opportunities for me.  Ole writes about high-level topics in an understandable way and even though our business is too small for this kind of technology full-scale this is truly inspirational in terms of what we have to do and how else have to think data management when our business expand during the coming years.  Before reading the book the subject was kind of a black box to me but now I understand the interplay between different layers of structuring and organising complex data. Making it available to all. The last chapter (I highly recommend reading the entire book) finishes it all off with a perspective on data search that really took me by surprise… it sort of put it all into place. If you are serious about understanding searching for and in data this is a must-read. I highly recommend it!

Velskrevet og interessant indføring i datakatalogets mysterier. Ole Olesen-Bagneux skriver flydende og præcist og formidler et relativt tørt emne med anvendelse gode eksempler i et let overskueligt format. Meget anbefalelsesværdig!

“It’s the unlocking of data that is becoming the do-or-die of companies in the 2020s”. This is my favourite sentence from the book ‘The Enterprise Data Catalog’ and it’s one of the strong points made in the well structured and well written book by Ole Olesen-Bagneux. Reading the book made me realise what I was missing from the Domain Driven Design when doing data governance and it gave great inspiration for how to organise and improve information retrieval in a data catalogue. It considers various types of users and stakeholders of a catalogue, and it brings in the aspect of using your data catalogue to discover data, which I find have been overlooked by some vendors on the market. The book provides you excellent background knowledge if you are in the beginning of choosing a data catalogue provider, but the book can also be of inspiration for the advance user/provider that wants to improve the use and value of a data catalogue. As a reader with a background in Information Science it is powerful to see our theories and methods translated into modern context of cataloguing and mapping data, and you should definitely give it a read if you work with metadata, cataloguing, knowledge systems construction, or if you’re just a fan of domain thinking and domain-studies in general.
