دانلود کتاب معماری مدالیون(Medallion) ساختمان داده- طراحی با Delta Lake و Spark

About a year ago, in early 2024, I was prepping up for my third architecture design workshop of the week. As I stood in front of the eager participants, the conversation naturally turned to Medallion architecture. Participants started firing off questions: “What are the best practices?” “What do other enterprises do?” “Is this architecture a valid pattern for larger organizations operating across multiple domains?” “Does data mesh replace a lakehouse architecture?” “How do we implement the Silver layer in practice?” Every time I discuss the concept of Medallion architecture, it feels like I’m unraveling a complex puzzle. Despite its simplified layered approach to addressing various architectural concerns, the persistent lack of clear definitions and descriptive guidelines often leads to a flurry of questions, sparking confusion and inefficiency within organizations. This recurring theme prompted me to take decisive action: I decided to write a book that would provide a comprehensive guide to Medallion architecture, offering clarity and direction to professionals navigating this complex landscape. Over the years, I’ve dedicated myself to studying Medallion architecture extensively. My research and practical experience have revealed its significant overlap with data warehousing, governance, metadata management, and data modeling. These elements are not isolated; they are interconnected, each impacting the other profoundly. Aware of the ongoing challenges and recognizing the need for clarity among professionals, I was driven to create a resource that could light the way to understanding. I also learned that, like many things in life, good designs come with nuances. Building Medallion Architectures is my effort to demystify a complex subject. Before I started writing, I surveyed professionals to understand what readers might expect from this book. Most practitioners were looking for a hands-on guide and insights into complex topics like data mesh and generative AI, with many emphasizing the importance of governance and security. They also expressed a strong desire to learn from the experiences of other real-world organizations. I’ve kept all this feedback in mind while writing this book. I cover a wide range of topics related to Medallion architecture. However, based on the feedback I received, I had to prioritize some areas over others. As a result, you won’t find in-depth discussions on continuous integration and deployment, DataOps, machine learning, data lineage, or business data modeling here. These topics are indeed valuable, but they require their own detailed exploration, which is beyond the scope of this book. Instead, I chose to focus on the most pressing and impactful areas to ensure the insights you gain are practical and actionable. My goal is to meet your expectations and provide clear, straightforward guidelines and definitions to help you effectively implement Medallion architectures. Whether you’re a newcomer, still wrapping your head around lakehouse architecture, or gearing up for your first project, let’s navigate this complex terrain together. This book is structured to cater to a diverse audience, with each section designed to address different aspects of Medallion architecture. It begins by exploring the evolution of data architecture, highlighting key practices from the past and present. It then introduces the core concepts of Medallion architecture with clarity and without bias. Moving from theory to practice, the book offers detailed tutorials for hands-on engagement and learning. Additionally, it features case studies that illustrate successful implementations of Medallion architecture across various enterprises, providing insights into best practices and common pitfalls. Finally, the book discusses the latest trends such as data mesh, data governance, data contracts, security, and artificial intelligence (AI), offering valuable perspectives for those looking to enhance and scale their data architectures. Having said this, I hope that Building Medallion Architectures proves to be an invaluable resource for everyone from novices to seasoned professionals. Whether you’re seeking a solid introduction, hands-on practice, real-world applications, or advanced knowledge, this book has something to offer.
