MongoDB Schema Design: Practical Applications and ImplicationsMongoDB
Presented by Austin Zellner, Solutions Architect, MongoDB
Schema design is as much art as it is science, but it is central to understanding how to get the most out of MongoDB. Attendees will walk away with an understanding of how to approach schema design, what influences it, and the science behind the art. After this session, attendees will be ready to design new schemas, as well as re-evaluate existing schemas with a new mental model.
The session conducted by DSC DYPCOE Pune. It's based on the book "Clean Code" by Robert C. Martin.
Any fool can write a code which machine can understand, good programmer write a code which humans can understand.
In this Meetup Victor Perepelitsky - R&D Technical Leader at LivePerson leading the 'Real Time Event Processing Platform' team , will talk about Java 8', 'Stream API', 'Lambda', and 'Method reference'.
Victor will clarify what functional programming is and how can you use java 8 in order to create better software.
Victor will also cover some pain points that Java 8 did not solve regarding functionality and see how you can work around it.

Docker provides a new, powerful way of prototyping, testing and deploying applications on cloud-based infrastructures. In this seminar we delve into the concept of Docker containers without requiring any previous knowledge from the audience.
This talk will describe the development and implementation of WindyGrid, an online geographic information system, that presents a unified view of City of Chicago operations to improve agency coordination, incident monitoring and response, and to identify trends. In lieu of reviewing numerous and disparate reports, WindyGrid gives key personnel access to 911 and 311 service calls, asset locations, building information, tweets, and other critical information in one place. To enable this, data from siloed City source systems are regularly ETLed into MongoDB. The City’s implementation of MongoDB has been architected to support multiple shards along with three tiers to allow for expanding query access and redundancy.
Symfony2 and MongoDB - MidwestPHP 2013 Pablo Godel
In this talk we will see how to use MongoDB in Symfony2 projects to speed up the development of web applications. We will give an introduction of MongoDB as a NoSQL database server and look at the options on how to work with it from Symfony2 and PHP applications.
MongoDB is the coolest NoSQL DB around, partially because it's simple-by-design philosophy. Without transactions or joins, all the bad vibe of SQL is gone.
In this presentation I demonstrate how to get started with MongoDB in the cloud using Mon
How to write multi threaded applications using Qt:

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

5. Mongo Is Awesome
Data Store for
JSON Objects
{
“Name” : “Rose Tyler”
}
Saturday, February 2, 13
6. JSON Objects
A JSON Object is a
collection of key/
value pairs {
"name" : "Rose Tyler",
Keys are simple "race" : "Human",
strings "body parts" : [ "head", "legs"]
}
Values can be:
Numbers, Strings,
Arrays, Other
Objects, and more
Saturday, February 2, 13
15. CRUD Operations
Create, Read, Update and Destroy Data
Saturday, February 2, 13
16. Mongo CRUD
Create is called insert
Read is called find
Update is called update
Destroy is called remove
Saturday, February 2, 13
17. Mongo CRUD
From a developer’s perspective, MongoDB operations are
the same through the driver and through the console
In both cases, operations look like function calls or
method invocations
We’ll use mongo shell for the rest of this chapter
Saturday, February 2, 13
18. Inserting Data
Use the command insert or save to insert a new object
db.collection.insert( obj );
db.collection.insert( array );
Saturday, February 2, 13
19. Inserting Data
Inserting to a new collection creates the collection
Inserting an object with an _id key, it is used as the
object’s id (and must be unique).
Saturday, February 2, 13
21. Reading Data
find and findOne perform read operations
Both take a query
find returns a cursor
findOne returns an object Optional: Fields to
fetch
db.collection.find( <query>, <projection> )
Saturday, February 2, 13
22. Query Document
An empty (or missing) query document returns
everything
db.collection.find({})
db.collection.find()
Saturday, February 2, 13
23. Query Document
Each key/value pair in the query document imposes a
condition on the results (objects that match).
db.movies.find({ “genre” : “indie” });
db.books.find({“pages” : { “$gt” : 100 }});
Saturday, February 2, 13
24. Query Document
Query Object
Each key/value pair in the query document imposes a
condition on the results (objects that match).
db.movies.find({ “genre” : “indie” });
db.books.find({“pages” : { “$gt” : 100 }});
Saturday, February 2, 13
25. Query Document
A compound query means a logical AND on the
conditions.
db.inventory.find(
{
“type” : “snacks”,
“available” : { “$lt” : 10 }
});

30. Update
Update operations modify existing data in the DB
Mongo supports two update commands:
update() and save()
Update is the more general (and complex)
Saturday, February 2, 13
31. Update
The general form for update is:
db.collection.update(
<query>, <update>, <options> )
Which Entries What to do with
to update them
Saturday, February 2, 13
32. Update
The second argument to update() is an operator object
It tells update what to do with the data
Some keys you can use: “$set”, “$inc” “$push”,
“$pushAll”, “$addToSet”, “$pop”, “$pull”, “$pullAll”
Saturday, February 2, 13
33. Update: set
$set modifies a value or add a new value
Example:
db.posts.update(
{ title: “Why Is Your Cat Unhappy” },
{ $set : { “archived” : true } }
);
Saturday, February 2, 13
34. Quiz: $set
What happens here ?
db.cats.update(
{ color: “white” },
{ “$set” : { “owners” : [“John”, “Jim”] } }
);
Saturday, February 2, 13
35. Quiz: $set
Update owners array of the first cat with white color
If you want to update all objects, use multi
db.cats.update(
{ color: “white” },
{ “$set” : { “owners” : [“John”, “Jim”] } }
{ multi : true }
);
Saturday, February 2, 13
36. Deleting Data
remove() deletes objects from a collection
Takes a query and possibly a <justOne> arguments
Examples:
db.posts.remove({ “author” : “Father Angelo” })
db.music.remove({ “genres” : “pop” })
db.posts.remove({ “tags” : “funny” }, 1 );
Saturday, February 2, 13
