![What is NoSQL?
A NoSQL (originally referring to "non SQL",
"non relational" or "not only SQL")[1] database
provides a mechanism for storage and retrieval
of data which is modeled in means other than
the tabular relations used in relational
databases.

GraphTalks Rome - Selecting the right Technology
Dirk Möller discusses selecting the right database technology, with a focus on graph databases like Neo4j. He outlines the benefits of graph databases over relational and NoSQL databases for connected data, including high performance, easy maintenance, and seamless evolution. Möller also provides examples of common use cases where graph databases have business benefits in areas like recommendations, fraud detection, and network operations.

- 13. What is NoSQL? KVStore Key-value (KV) stores use the associative array (also known as a map or dictionary) as their fundamental data model. In this model, data is represented as a collection of key-value pairs, such that each possible key appears at most once in the collection Document Store A document-oriented database, or document store, is a computer program designed for storing, retrieving, and managing document- oriented information, also known as semi-structured data. ... XML databases are a subclass of document- oriented databases that are optimized to work with XML documents

Relational DBs Can’tHandle Relationships Well • Cannot model or store data and relationships without complexity • Performance degrades with number and levels of relationships, and database size • Query complexity grows with need for JOINs • Adding new types of data and relationships requires schema redesign, increasing time to market … making traditional databases inappropriate when data relationships are valuable in real-time Slow development Poor performance Low scalability Hard to maintain

- #19 More competition validates the space
- #21 Titan is not on a firm technical foundation. Even if they were, they’re not sitting on a firm commercial foundation: no outside funding, 7 guys, primary business focus is consulting not product OrientDB is in the “Native full stack” category, but their technology platform is shaky because they haven’t had the full 5-7 years of being shaken out in production. And their commercials are quite shaky for all the reasons we’ve discussed.

- #27 And deriving value from data-relationships is exactly what some of the most successful companies in the world have done. Google created perhaps the most valuable advertising system of all time on top of their search-enginge, which is based on relationships between webpages. Linkedin created perhaps the most valuable HR-tool ever based on relationships amongst professional And this is also what pay-pal did, creating a peer-to-peer transaction service, based on relationships.
- #30 Presenter Notes - Challenges with current technologies? Database options are not suited to model or store data as a network of relationships Performance degrades with number and levels of relationships making it harder to use for real-time applications Not flexible to add or change relationships in realtime
- #32 Relating data requires building JOIN logic in the application and more data movement over the network
- #33 Presenter Notes - How does one take advantage of data relationships for real-time applications? To take advantage of relationships Data needs to be available as a network of connections (or as a graph) Real-time access to relationship information should be available regardless of the size of data set or number and complexity of relationships The graph should be able to accommodate new relationships or modify existing ones

- #36 Presenter Notes - Higher Level Value Proposition Everyday, new data is being created at a volume never seen before. And we see that this data is getting even more connected. People communicating as customers, employees, friends, influencers. Customers purchasing products, services or content, expressing their likes and dislikes. Digitization of processes and more data elements for each step. And with Internet of Things (IoT), we have the same thing repeating but with machines talking to each other. There is tremendous value in the knowledge of this relationship information for real-time applications. Examples are Connect a user’s profile and purchases to other users and increase revenue through recommendations for new products and services Reimagine your master data - HR, Customer or Product as a connected model and identify ways to reach customers, improve their experience, identify the best people to staff on projects and more View your individual data elements as part of a process to determine fraud detection or process bottlenecks Companies like Google, LinkedIn and PayPal have done exactly that. Reimagine their data as a network (or a graph) and use the relationship information
