This document provides an overview of non-relational databases and MongoDB. It discusses the advantages of non-SQL databases like scalability and flexibility compared to RDBMS. It also covers MongoDB features like document-oriented data structure, dynamic queries, indexing, replication and sharding. The document demonstrates basic MongoDB operations in Ruby like connecting to a database, inserting and querying documents.
Use of No-SQL databases in web applications is becoming increasingly common. In part this is because they work well with rapid application development due to their schema-less nature. And partly because they scale well in a cloud-based environment without too much effort.
MongoDB is one of the many No-SQL database technologies available today. It's schema-less nature works very well with rapid application development nature of ColdFusion. Unlike other No-SQL databases, it offers the ability run arbitrary queries against databases without having to first write map-reduce functions. It also has some other interesting features like capped collections with asynchronous write ability.
In this session, Indy takes you through some common use-cases for considering MongoDB with ColdFusion applications, contrasting it with other No-SQL databases like CouchDB. And he shares his experiences of using it with cloud-based ColdFusion applications. The aim of the session is to provide an overview of using MongoDB with ColdFusion so that you have another tool to consider when working on your next web application.
This was presented at CFObjective, Melbourne, November 17-18, 2011.

Explore the Cosmos (DB) with .NET Core 2.0Jeremy Likness
CosmosDB, formerly referred to as DocumentDB, is Microsoft's cloud-based NoSQL distributed database available on Azure. CosmosDB provides unique service level agreements, fine-grained control over consistency and availability, and provides multiple interfaces including SQL, MongoDB, and Graph-abased query language. Learn how to create a CosmosDB database and connect to it with .NET Core using C# that can compile and run on Windows, MacOS, or Linux machines.
MongoDB and Ecommerce : A perfect combinationSteven Francia
Presentation given at the MongoDB NYC Meetup by Steve Francia, VP of Engineering at OpenSky. OpenSky uses MongoDB to develop the next ecommerce platform. OpenSky also uses Symfony 2, Doctrine 2, PHP 5.3, PHPUnit 3.5, jQuery, node.js, Git (with gitflow) and a touch of Java and Python. The OpenSky team contributes back to many of these technologies and employs core members of the Symfony 2 and Doctrine 2 teams.
This is part 1 of the Azure storage series, where we will build our understanding of Azure Storage, and will also learn about the storage data services, and the types of Azure Storage. Last but not least, we will also touch base on securing storage accounts
In the second part, we will continue with our demo on creating and utilizing the Azure Storage.
MongoDB is the most famous and loved NoSQL database. It has many features that are easy to handle when compared to conventional RDBMS. These slides contain the basics of MongoDB.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

DevOps and Testing slides at DASA ConnectKari Kakkonen
My and Rik Marselis slides at 30.5.2024 DASA Connect conference. We discuss about what is testing, then what is agile testing and finally what is Testing in DevOps. Finally we had lovely workshop with the participants trying to find out different ways to think about quality and testing in different parts of the DevOps infinity loop.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

4. CAP Theorem
Pick two
С A • Consistency
• Availability
P • Tolerance to network
Partitions
http://www.cs.berkeley.edu/~brewer/cs262b-2004/PODC-keynote.pdf
5. ACID & BASE
• Atomicity • Basically Available
• Consistency • Soft state
• Isolation • Eventually consistent
• Durability
6. ACID vs. BASE
ACID BASE
• Strong consistency • Weak consistency
• Isolation • Availability first
• Focus on “commit” • Best effort
• Nested transactions • Approximate answers
• Availability? • Agressive (optimistic)
• Conservative • Simpler!
• Difficult evolution • Faster
(schema)
• Easier evolution
7.
8. Scalability & Intro
Performance
memcached
Key/Values store
RDBMS
Depth of Functionality
9. Features
• Collection oriented storage: easy storage of object/
JSON -style data
• Dynamic queries
• Full index support, including on inner objects and
embedded arrays
• Query profiling
• Replication and fail-over support
• Efficient storage of binary data including large objects
(e.g. photos and videos)
• Auto-sharding for cloud-level scalability (currently in
alpha)
• Commercial support available
10. Great for
• Websites
• Caching
• High volume, low value
• High scalability
• Storage of program objects and json
11. Not as great for
• Highly transactional
• Ad-hoc business intelligence
• Problems requiring SQL
13. Collection
• Think table, but with no schema
• For grouping into smaller query sets (speed)
• Each top entity in your app would have its own
collection (users, articles, etc.)
• Full index support
14. Document
• Stored in collection, think record or row
• Can have _id key that works like primary key in
MySQL
• Two options for relationships: subdocument or
db reference
