Martin Fowler - Author, Speaker, Consultant & General Loud-mouth on Software Development
ABSTRACT
Martin gives a rapid introduction to NoSQL databases: where they came from, the nature of the data models they use, and the different way you have to think about consistency. From this he outlines what kinds of circumstances you should consider using them, why they will not make relational databases obsolete, and the important consequence of polyglot persistence.

Its just mindboggling to imagine about the level of clarity Martin speaks with. There are some people who attract you with their oratary skills and I pledge this guy is one such kind

[@nikitadrozdovskii2140]

I wish I could add an extra "like" every time I agree with what he is saying or he blows my mind with how he puts all the concepts I learned separately into one global picture.

[@CosasCotidianas]

Definitely this

[@hynjus001]

Martin Fowler is just amazing

[@giorgosargyriou5856]

I don't know if I am young or new in the subject, but that's what I call "perfect teaching". This guy is amazing! For many years I was disappointed from my professors and their (in)ability to teach contagiously. This man justifies my (so called) nagging.

[@jameswainwright5217]

+Giorgos Argyriou He's very impressive.

[@NJ-wb1cz]

+Giorgos Argyriou You have to keep in mind, that he is not only teaching, but also promoting. As in, he sort of glosses over the fact that the vast vast majority of your real projects will never ever need NoSQL as your primary data storage, and using NoSQL database where you really need something relational is a far more expensive mistake, than the other way around.

[@NJ-wb1cz]

***** Yeah, he promotes NoSQL in general, not as a replacement - but that's what people inevitably take out of such well constructed presentations. The fact is, most developers already use relational DBs for everything and to insert NoSQL in your workflow you have to replace SQL in some way. Now, if you are using filesystem or in-memory hash table as your storage engine - then yeah, NoSQL could extend your horizons with very little performance hit. Otherwise you are incurring these massive penalties on architecture or feature set or extendability or stability of your applications in the name of mythical features or performance levels that you don't actually need. He doesn't spend much time explaining, which NEW problems are now solvable, and which of the old ones are definitely NOT - he spends most of the time straight out praising NoSQL.

[@NJ-wb1cz]

***** See, you're doing it even worse. People think "fast and scalable? well duh, I need fast and scalable everywhere!" Except you don't mention, that "fast" could mean "slower than MySQL or Postres on real workloads", and "scalable" could mean "scalable far beyond what you'll ever need or use", and you also don't mention "forcing simple data structures", "rigidity of data representation", "inability to make deep changes", "inability to use any sort of advanced cross-cutting analytics", "unpredictable performance on very similar tasks from business perspective", etc. So no, if the purpose is truly to have a fast and scalable database, then you have to return to planning stage and completely change your decision process to better reflect actual needs of your application and not some generic marketing-talk.

[@NJ-wb1cz]

***** So... why then reply at all if your answer is misleading and incomplete, and people shouldn't take it into consideration?

[@hnasr]

21:40 most important part of the presentation. How to make a choice between relational and nosql...

[@AnthonyBecker9]

44:40 has further details

[@alexanderveprik3331]

Precisely. I feel like this is the most decisive quality.

[@andriinikitin6139]

This video gave me more than 2 days reading articles and watching other vids non-stop

[@brandonhunter3036]

10 years later and this was very accurate.

[@pawel753]

40:40 the best explanation of CAP theorem I've ever heard (+ previous example of booking a hotel room at 37:52)

[@Sebastinator]

This dude is amazing! Will watch all his conferences!

[@cliveboulton]

The best NoSQL talk I've come across.

[@marcdraco2189]

Just great! What a gift to be so fluid and yet so comprehensive.

[@nagaraj-ol3xe]

One of the best intro about NoSQL Dbs and especially the CAP theorem

[@saggie1984]

Glad that I found this video. Explains almost everything you need to know about NoSQL. Speech is absolutely perfect.

[@kevinzhang8974]

Excellent presentation. Simple, plain English and examples to help understand the basics of NoSQL concept. Thank you Martin! Kevin

[@AriKhuu]

this talk is amazing thank you for sharing!

[@shrutighughal8171]

That's much better explanation of CAP theorem than what you typically find online...

[@parishchic97]

This was a fantastic presentation! I am fairly ignorant to all of these concepts, and I am walking away with a better understanding of each. Thank you!

[@lalanashree3962]

Wholesome video, which covers every topic of NOSQL !!!

[@nishikanttayade7446]

He is THE BEST teacher I ever had!

[@slavikzorin6906]

Martin is the most lucid speaker on pretty much any complex topic in computing. I love this 50 minute talk. A great intro into the NoSQL movement. I did think that the explanation as to why NoSQL may succeed where OODBS failed was no so convincing and would have loved to hear more on this particular topic. Highly recommended!

[@TheOceanLoader]

Great explanation of the different models of NoSQL databases. Martin Fowler does his usual breakdown of complicated subjects into informative presentations.

[@brynncurry6112]

Great breakdown of NoSQL. I appreciate the part of the talk where you show the graphic of using multiple data storage types to meet a systems needs using polyglot persistence. This video has made me think even deeper about the full systems interaction between the different data stores.

[@vijayamurugand6407]

Martin your talk made me understand a hell a lot about NoSQL Which can't even gained after 2 years of practical experience. If someone had kind of presentation for SQL it might have been used better in the industry. It's best!!

[@decki86]

if only everyone teaches like this...

[@DoNuT_1985]

I was just thrown into NoSQL for a project a week ago and found this very interesting, as well as entertaining. It's really hard to get rid of all these ORM-related paradigms first, but I love the relief that comes with simplicity.

[@MoizRaja]

Martin Fowler is very good at "distilling" complex stuff into easy to understand concepts. Excellent talk!

[@anandakumarsanthinathan4740]

Brilliant presentation. Today is the 16th of December. His birthday is two days from now. Happy birthday, Martin Fowler.

[@laexpearl]

Great talk on NoSQL by Martin Fowler. Incredibly articulate.

[@shikhashah8253]

Best explanation! Thank you for such good content!

[@sigmundkreuzer9655]

A great presentation over the different NoSql approaches. Thanks for sharing.

[@MessiahTheMessengerOfGod]

Martin Fowler, is a great man. The conference is perfect !

[@FeelsDonkMan]

Fantastic talk, really interesting. Going through something similar now. I think one of the other things about aggregate databases is that because there's no explicit schema, documents can end up in unexpected states, unless you verify everything before an update via the implicit schema which is not very feasible. You basically can't tell how something went wrong in your documents at that point which is pretty worrying.

[@EssamAlmuqri]

It's been sometime since I started looking for what is NoSQL and what the fuzz all about. I think this video is simply my answer.

[@westfield90]

I found this to be one of the best presentations I’ve ever seen. It was very clearly explained. I wish he would do a follow up now 6 years later and revisit this space and how has it changed or is it still pretty much back where it was in 2012, As a complete Noob I’m wondering what has changed in the past six years.

[@draco2848]

Thank you Martin for your awesome talk.

[@jayeshchandrapal]

Very well thought out, and steady continuous stream of presentation. Thanks for sharing.

[@venknar]

Awesome talk and good introduction to NoSQL storage solutions. Must watch for getting to know the basics of NoSQL

[@jordanradkov2910]

Great Vid. I often find myself losing focus during such tech talks, but that was not the case here! Props to Mr. Fowler !

[@PlatformsLLC]

Martin Fowler has done more to help me be a better coder than anyone else alive. His book on refactoring is the single most useful practical programming text I've ever read. Thank you sir!

[@rounakjain5774]

Thanks for the valuable insights!

[@pinkylover911]

not only an excellent instructor but also super funny

[@srinivasanisetty6894]

Splendid method of introducing to the concept of NoSQL. Must watch for anyone new to this domain. Thankyou Martin.

[@pdxholmes]

Great introductory talk. The best part of it was that he didn't take a giant steaming dump on relational models which a) still pay most of our bills in direct or indirect ways, and b) still absolutely have a place in the world of data. I think his premise of 'polyglot persistence' is absolutely where things are headed. I've already seen some pretty neat implementations using RDBMS as the final authoritative backing store, but having clustered MongoDB instances as mostly-fresh satellite caches.

[@ckakunje]

Always feels good to listen from the Guru.

[@ohad7]

Excellent lecture. Thank you for sharing.

[@ajay1124]

Martin Fowler, thanks you are the best

[@sam271183]

That was a really good talk.. Thanks!

[@IsidroMoran]

Best noSQL intro ever seen

[@LucasKjaero]

Good talk, and I agree that it's good to know multiple ways of storing data. He explains things well. However, I question the recommendation of using the immature and experimental technology for your mission critical systems: it's probably better the other way around.

[@srinivasakadiyala7677]

Thanks Martin for a nice orientation to NoSQL.
