This document summarizes an OTA (Online Travel Agency) platform that uses MongoDB as its database. The platform allows one stop shopping for hotels, flights, tours and other travel products. It also facilitates B2B travel. MongoDB is used because it is fast, allows flexible schema design, and saves time on database tasks like handling dynamic data through embedded documents. Some data is stored in referenced collections to handle large amounts of data like room rates and media files.
Using semi-structured data in modern applicationsMariaDB plc
JSON is the de facto standard for consuming and producing data from web, mobile and IoT apps, but relational databases are required for reliability – enforcing data integrity and providing durability with transactions. They're not mutually exclusive. MariaDB TX introduced SQL functions for validating, indexing and querying JSON documents – and for returning relational data as JSON documents, or JSON documents as relational data. In this session you will learn how to read, write, index and query semi-structured/non-traditional data with hands-on examples.

[MongoDB.local Bengaluru 2018] Jumpstart: Introduction to Schema DesignMongoDB
Presented by: Saurabh Kashikar
Abstract: MongoDB’s basic unit of storage is a document. Documents can represent rich, schema-free data structures, meaning that we have several viable alternatives to the normalized, relational model. If you are new to MongoDB, learn the schema design basics in this introductory session. This session will help you model basic relationships in MongoDB.
What You Will Learn:
- The fundamentals of the MongoDB document model.
- How to model 1-1 and one-to-many (1-N) relationships in MongoDB.
- How to model many-to-many (N-N) relationships in MongoDB.

Building A Relevancy Engine Using MongoDB and Goardan-bkennedy
Big data and analytics is becoming incredibly important as information on people and their lives become more readily available. Companies are looking for ways to acquire, store and process personal information on their users to help provide intuitive experiences and sell products or services. Using Go and Mongo, you can build these analytic engines with all the flexibility, scalability and performance you need. In my talk I will show how you can leverage Go and MongoDB to load customer data and both public or personal offer feeds at runtime. Then using a Go based web service, build rules to identify products and services your customers will want.

Building your first app with CloudBoost.io
When it comes time to select database software for your project, there are a bewildering number of choices. How do you know if your project is a good fit for a relational database, or whether one of the many NoSQL options is a better choice?
In this webinar you will learn when to use MongoDB and how to evaluate if MongoDB is a fit for your project. You will see how MongoDB's flexible document model is solving business problems in ways that were not previously possible, and how MongoDB's built-in features allow running at scale.
Topics covered include:
Performance and Scalability
MongoDB's Data Model
Popular MongoDB Use Cases
Customer Stories
Sometimes , some things work better than other things. MongoDB is great for quick access to low-latency data; Treasure Data is great for infinitely scalable historical data store. A lambda architecture is also explained.
How to get the best of both: MongoDB is great for low latency quick access of recent data; Treasure Data is great for infinitely growing store of historical data. In the latter case, one need not worry about scaling.
Webinar: Elevate Your Enterprise Architecture with In-Memory ComputingMongoDB
The advantages of in-memory computing are well understood. Data can be accessed in RAM nearly 100,000 times faster than retrieving it from disk, delivering orders-of-magnitude higher performance for the most demanding applications. Examples include real-time re-scoring of personalized product recommendations as users are browsing a site, or trading stocks in immediate response to market events.
In this webinar, we’ll briefly explore the trends driving in-memory computing (IMC), the challenges that surround it, and how MongoDB fits into the big picture.
Topics covered in this session will include:
- IMC use cases and customer case studies
- Critical capabilities and components of IMC
- How MongoDB plays a role in an overall IMC strategy within your enterprise architecture
- Suggested architectures related to MongoDB’s in-memory capabilities:
-- Integration with Apache Spark

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

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.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
5. About Our Application
Travel Ideas
• Travel News, up-to-date info all around the world
• Travel Tips
• based on places (countries, cities, areas)
• covers various aspects, such as overview, sightseeing,
eating/restaurants, shopping and events
• Travel Stories, submitted by members
• Photos and Videos
• Blog, monthly theme posts based on event calendar
8. Technology Overview
These are stuff that we use behind our apps
Web Server : Apache
Application : PHP
CodeIgniter (PHP MVC Framework)
Backbone.js (Javascript Framework) with its friends
Require.js, Underscore.js, Mustache.js, jQuery
Database : MongoDB
9. Why MongoDB?
• It’s fast
• Development speed time faster
• No join, no relation
• No sql injection worries (you bet)
• Reduced database requests
• Super flexible schema design
• Fewer tables/collections used
10. What do we store in
MongoDB?
All datas are stored in MongoDB.
Including important data such as bookings,
inventory, etc.
12. Saving huge amount of time
on database stuff
spreadsheet is more than enough
db structure alters and changes
straight on the code
13. With RDBMS approach, dynamic
data is pain in the a*s
Embedded documents to the rescue
This is how we handle dynamic data on our apps
14. Use Case
• Hotels may have multiple contracts
• One hotel contracts may have multiple
bank accounts
• Hotels may have multiple facilities
• Hotel facilities have several categories
15. Schema Design
MongoDB approach
RDBMS approach
more or less like this...
plus two/three tables for reference data
16. And now the query...
“get me hotels with its facilities which has BCA account in
Jakarta only”
RDBMS approach
SELECT * FROM hotels
INNER JOIN facilities ....
INNER JOIN photos ....
AND THEN JOIN the_banks ....
AND OF COURSE JOIN the_locations ....
AND JOIN the_city ....
WHERE
the_city IS “Jakarta”
AND
the_banks IS “Bank BCA”
We all know JOINs are expensive.
Use EXPLAIN on SQL to see it
17. And now the query...
“get me hotels with its facilities which has BCA account in
Jakarta only”
MongoDB approach
db.hotel.find( { “locations.city” : “Jakarta” , “contracts.banks.name” : “Bank BCA” } )
One single query to fetch all the data we need
18. Be wise when choosing which
Data Models are used
Embedded documents not applied to all data model
We use referenced model when it comes to very
large record sets / documents
19. Model Referenced One-to-Many
Relationships between Documents
http://docs.mongodb.org/manual/tutorial/model-referenced-one-to-many-relationships-between-
data-modeling-publisher-and-books
Normalize the data, just like RDBMS approach but
using “fake” relationship
Use key/id to store references between two documents
20. Use Case
• Each hotel may have multiple room types
• One room type may have up to 10
photos/videos
• Each room type have their rate/price
• Room rates based on contract period
(one or more years)
• Room rates stored daily
21. Use Case
Example :
A Hotel has 5 room types
Each Room type has 10 photos
Hotel contract period is one year
5 room types x 10 photos = 50 documents
5 room types x 365 room rates = 1825 documents
Total documents for 1 hotel :
1 + 5 + 50 + 1825 = 1881 documents
22. Use Case
Example :
Total documents for 1 hotel :
1 + 5 + 50 + 1825 = 1881 documents
If we have 1500 hotels then 1881 x 1500 = 2.821.500
What if we have more than 1500 hotels?
What if a hotel have more than 5 room types?
What if a room type has more than 15 photos?
23. And then we decided to separate the
collections that potentially has huge data
example : room_rates, hotel_media, etc
24. More to see...
