In this book, the Entity-Attribute-Value (EAV) model is portrayed as an Anti-Pattern. Although I must admit that a proper relational schema is almost always the best approach when designing an enterprise system, there are use cases when the EAV model is justified.
In this post, I’m going to explain when to use EAV and how to transpose a ResultSet so that rows become columns.
This post is a review of what this book is all about and why you should be interested in reading it.
If you are a backend developer, a team leader or a software architect, this book must be on your reading list. While a junior developer might find the book interesting too, you got to have some background knowledge so that everything falls into place.
The book is a very detailed summary of how database systems work. From relational databases to data warehouses, key-value stores, column-oriented databases, Martin Kleppman describes a great deal of aspects like:
storage engines and indexing
transactions and concurrency control
distributed systems and consensus algorithms
Why you should buy it?
Although some concepts are not very easy to understand, Martin Kleppman does a very good job explaining all these concepts using down-to-earth examples.
The book is a summary of hundreds of research papers, books, and other scientific articles that would require you a great deal of effort to go through all of them, albeit to understand them. Hopefully, you don’t have to since the book is exactly what you need to get a better understanding of how data management systems.
I strongly recommend you buy this book. Although I read it, I’m sure that I’ll come back to it in future to validate that I haven’t forgotten anything I learned from this book.
Exactly one year ago today, I started working as a Developer Advocate for the Hibernate team at Red Hat. Prior to joining Red Hat, I used to work as a software architect, and I didn’t have any clue what I would have to do as a Developer Advocate. So, I learned on the way.
This post is a summary of what this role is about, and what I’ve managed to accomplish.
