*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.

Already requested the download link twice and did not receive any emails. Please let me know what to to in order to obtain the download link.

Thanks!

I personally like to thank Aileen Agricola from the Neo Technology team so much for her great follow up.

She sent me an email with the direct download links for the PDF and .epub/.mobi links of the book.

Thank you so much for the great support and excellent attitude!!!

Thank you for making it available for free.

Thank you for the book

Graphs Theory was the buggyman for me back at the university, now it’s the lead database in the graphs field, and I JUST LOVE IT!

Have tried this twice and not received any emails (spam or otherwise).

I’d appreciate this being fixed as giving you marketing details without getting anything in return doesn’t encourage me to considerer your products.

Thanks!

For the record, Aileen from Neotechnology responded to my comment within 60 minutes and got me the link.

Thanks for keeping an eye on the comments and responding so quickly – confidence restored

Hello and thanks for the free e-book. I am really curious about this technology.

Thank you for making this excellent book on a little-understood yet very powerful technology available for free.

Where can I find the Errata?

The figure 3-1, is the direction of the arrow wrong?

Hi Luciano,

Yes, you are correct. Please view and submit Errata at: http://oreilly.com/catalog/errata.csp?isbn=0636920028246

Thanks!

Aileen

Aileen,

Already there! Thanks!

Thank you so much. Would it be possible for someone to point me towards resources for using graph db with python. Thank you.

Hi there,

Check out Neo4j and Python:

Have fun!

Thanks for this!

Thank you very much for providing this ebook free of charge. I have seen Neo4J but never cared to take a closer look until I watched a presentation in Infoq.

ok

thank you so much

Thanks very much.

Thank you, that was really cool!!

First, thanks a lot for giving this book for free. Second, can you make the e-book available in Kindle format? PDFs are hard to read on small screens (such as tablets or e-book readers).

Really thank You for making this sensational knowledge available for free!

Thanks, awesome work
