*Graph Databases*, published by O’Reilly Media, discusses the problems that are well aligned with graph databases, with examples drawn from practical, real-world use cases. This book also looks at the ecosystem of complementary technologies, highlighting what differentiates graph databases from other database technologies, both relational and NOSQL.

*Graph Databases* is written by Ian Robinson, Jim Webber, and Emil Eifrém, graph experts and enthusiasts at Neo Technology, creators of Neo4j, the world’s leading graph database.

thanks alot!!!

How about modelling a family tree/genealogy using graph database

Hi Tushar,

Yes, graph database are a natural fit to family trees and we have customers doing just that. Check out this fun family tree – Games of Thrones – on our Learn Neo4j with Cypher page: http://www.neo4j.org/learn/try

Shouldn’t the arrows in Fig. 3.1 be pointing in the opposite direction in order to make the figure congruent with the ASCII art Cypher expression below the figure?

Thank you very much. This will be very useful.

Thank you very much.

Thanks for this! Now I don’t have any excuses more to get deeper in touch with graph databases.

Thanks for making it freely available!

Thank you!

Thank you for sharing!!!

Many thanks for your kindness!

Thank you very much! I’m very grateful for this e-book.

Thanks a lot; highly interesting subject.

Thank you

Cool thanks!

Thanks!

Thanks for the book. I want to know more about graph databases, despite I already have been using Neo4j

Thanks,

Álvaro

Thanks for this interesting book.

i supposed that graph database is more convinient to represent real word objects naturally

Thanks for sharing this!
