GraphQL and graph databases.

Four basics behind a graph database areNodes: The primary data elements

Relationships: How two nodes are connectedNodes may have multiple relationships

Properties: Attributes of a node or of a relationship

Labels: How nodes are described and grouped together as sets------
Nodes may have multiple labels

Labels get indexed and optimized, making it easier for them to be quickly located

Graph databases shift the focus of their data models to the relationships, which makes retrieving complex data structures much easier. They abstract nodes and relationships into one structure.But what is GraphQL ?

Graph databases

RDBMS, also known as Relational databases, are  structured and easy to query with a language like SQL, but they have limitations when it comes to unstructured data. And scaling usually means buying far more servers and even then , that has limitations.Not all data, however, is that easily organized. Semi and Unstructured data like IoT sensor data, social media,.  photos, videos, location-based GIS information, web or mobile activity, and usage metrics can’t be neatly broken down nor should be, but nobody wants a data swamp.  Things like Hadoop, HBase, Cassandra, MongoDB and other NoSQL or NewSQL like databases trade tables for documents or json or blocks or columnar like schemas and more.   https://www.business2community.com/brandviews/upwork/the-importance-of-graph-databases-in-an-increasingly-connected-world-02094654


Dont use IBM.. plain and simple

This is why nobody should use IBM hyperledger fabric and their blockchain.  In due time they will drop it like they drop and mismanage everything.  IBM was one this respected Company, even if they were the 'suits.'.  Now they are a joke in every single way and people really shouldn't trust anything they release or do.  Because soon enough it'll disappear or have no real support or updates.  IBM slashing AI staff ....

More clickbait blockchain nonsense articles

I read an article today on wine, alcohol and supply chain and rolled my eyes. 
Things like "…that solution is blockchain…Big companies like Walmart and large grocery stores are already using blockchain to manage supply chain management especially when it comes to food. "No, no they really aren't. Most of these big companies are actually full of it. They were full of it in the early big data and hadoop days.  They are full of it with the AI and machine learning and data science marketing pitches.  And they are definitely full of it when it comes to blockchain. Many do test.  Many don't have the time, resources or care.  And many don't even like new potentially disruptive Technologies.  Ever.  Decentralized blockchain?  Yeah Wal-Mart and Amazon and the big banks are all for that.  Not.  They are more for testing private permissioned centralized blockchains. And really there is some need for a system that doesn't give all the transaction information to the worl…

Help or more dystopian government control ?

Austin , Texas is piloting a program for putting the homeless population on the blockchain. Sounds great and great for society in general. There are some others around the globe attempting something similar.  There is a huge need for poor people and affordable housing as well as homelessness in many many cities and rural areas.     But will this be a program to help the homeless or a pseudo subtle attempt to control and know everything about everything and everyone by government agencies and corporations ?   I used to think a blockchain ID system was the perfect use case for many verticals and industries.  Now it's starting to look like another attempt at control by your typical governments and mega corporations.  Will it help the homeless or just be another tool to control more people?

Problem with blockchain and cryptocurrency

The underlying Technology behind blockchain and cryptocurrencies has phenomenal possibilities.  Even using  things like tangles and DAG graph theory (Hashgraph and IOTA in a sense) can change logistics and IOT.   The problem is it's a bunch of fake news. Hype nonsense.  Faux advisors who are snake oil salesmen and sales women with a fancy suit and nice story, not much else.  Decentralized and disruption?  Not really, it's worse than the dot com and COBOL 1999 ending the world nonsense.  It's clickbait and paid shills on all the media websites. It's great  peer reviews but no real world use case. Or private investors like Goldman Sachs under some other name pumping money into a 'decentralized' company.  The problem with Ethereum is it's not even decentralized. Most of these blockchains and cryptocurrencies and platforms are not.  Add the ICO and crowd funding and crowd building and crowd marketing nature and it's a lot of wanna be Steve Jobs and Elon Mus…

Cardano explained

https://youtu.be/Ja9D0kpksxwCardano is a fascinating study the more and more I dig deep into it. Things like RINA, sidechains, Ouroboros POS.  Plus it's all peer reviewed multiple times and attempts to build and design a highly Assurant platform is really impressive. Time will tell if it's ever released and used as they dream.  But technology wise , I sure hope they keep plugging away and making a great blockchain 3.0 system.

Cardano coming on strong

Cardano is an ambitious journey and just might be one of the best blockchain platforms , Technically speaking. And I think you can use some Haskell like programming concepts with it.  However, even though it's really received some love lately it's like the quiet blockchain for various reasons. Hopefully more and more people discover it and start using it. Maybe I will attempt something this week on it.  If I can.

Citizen health for blockchain and world

Very ambitious project to help change healthcare around the world.  Lots of opportunities and challenges. Open source and a market place for others to add on top.   Will be something great to be involved in and follow.  Citizen Health for the people and by the people.

The real blockchain or a tangle of graph theory?

So blockchain vs dags is coming.  Blocks and tangles.  Graph theory.  DAGs are (directed acylic graphs).  It's used a lot in big data technologies now like spark and tez and impala.  But in the blockchain space you now have IOTA and Hashgraph doing more of tangles and DAG theory vs blockchains,  but both these have detractors as in not much evidence they actually have a working implementation as they claim.  Time will tell.

Stellar consensus protocol

Amazon Healthcare anyone ?

What do you think about Amazon Healthcare?  Oh yeah Berkshire and JPMC are also involved so some big money backers and possibilities.   I wonder if they will utilize some blockchain Technologies to cut out some fees and Middlemen.

Ripple ripple xrp why

Do banks want Ripple ? That was the question, is the question and will be the question for a long time.  Ripple actually has built a very good ledger and platform for cross border exchanges.  And the SWIFT network is the middleman of the middelman centralized fallacy of fallacies.  However, Ripple has become another centralized version of a fallacy themselves. Hide blockchain from their marketing hype and what makes you think WOW?   That's the biggest problem for Ripple because they aren't some new decentralized eliminate the middleman philosophy at all.  They are just a different version of SWIFT.  Time will tell.
