The document discusses different types of NoSQL databases including key-value stores, wide column stores, document stores, and graph databases. It provides examples of databases for each type and describes their common uses and benefits. Some benefits mentioned are lower costs due to horizontal scalability, flexibility in schema and data structure, and better support for unstructured and semi-structured data. The document advocates for an approach called "polyglot persistence" where different types of databases are used together based on the specific needs of different parts of an application.
The NoSQL movement has introduced four new database architectural patterns that complement, but not replace, traditional relational and analytical databases. This presentation will introduce these four patterns and discuss their relative strengths and weaknesses for solving a variety of business problems. These problems include Big Data (scalability), search, high availability and agility. For each type of problem we look at how NoSQL databases take different approaches to solving these problems and how you can use this knowledge to find the right database architecture for your business challenges.

The presentation begins with an overview of the growth of non-structured data and the benefits NoSQL products provide. It then provides an evaluation of the more popular NoSQL products on the market including MongoDB, Cassandra, Neo4J, and Redis. With NoSQL architectures becoming an increasingly appealing database management option for many organizations, this presentation will help you effectively evaluate the most popular NoSQL offerings and determine which one best meets your business needs.
Relational databases vs Non-relational databasesJames Serra
There is a lot of confusion about the place and purpose of the many recent non-relational database solutions ("NoSQL databases") compared to the relational database solutions that have been around for so many years. In this presentation I will first clarify what exactly these database solutions are, compare them, and discuss the best use cases for each. I'll discuss topics involving OLTP, scaling, data warehousing, polyglot persistence, and the CAP theorem. We will even touch on a new type of database solution called NewSQL. If you are building a new solution it is important to understand all your options so you take the right path to success.
The rising interest in NoSQL technology over the last few years resulted in an increasing number of evaluations and comparisons among competing NoSQL technologies From survey we create a concise and up-to-date comparison of NoSQL engines, identifying their most beneficial use from the software engineer point of view.
Is emergence of NoSQL killed RDBMS and SQL? This slide discusses what is NoSQL and it's history. This also discusses briefly about polyglot persistence.
SQL Server 2016 is now in review! The newest version promises to deliver new real-time, built-in advanced analytics, advanced security technology, hybrid cloud scenarios as well as amazing rich visualizations on mobile devices.
There are many great reasons to move to SQL 2016, however if you are still working on SQL Server 2005 you may have another good motivator - the end-of-life clock of SQL 2005 is ticking down and support is about to end April 12, 2016.
In this deck we review the significant licensing changes introduced with SQL 2012. If our experience as Microsoft's Gold Certified Member has taught us anything - it is one thing. During migrations many of our clients get outright lost when trying to figure out the number of licenses they have or need. This often leads to under-deployment, and subsequently serious compliance issues with Microsoft. And yes, in some cases over-deployment means big savings back to your department.
What is NoSQL? How does it come to the picture? What are the types of NoSQL? Some basics of different NoSQL types? Differences between RDBMS and NoSQL. Pros and Cons of NoSQL.
What is MongoDB? What are the features of MongoDB? Nexus architecture of MongoDB. Data model and query model of MongoDB? Various MongoDB data management techniques. Indexing in MongoDB. A working example using MongoDB Java driver on Mac OSX.

DocumentDB is a powerful NoSQL solution. It provides elastic scale, high performance, global distribution, a flexible data model, and is fully managed. If you are looking for a scaled OLTP solution that is too much for SQL Server to handle (i.e. millions of transactions per second) and/or will be using JSON documents, DocumentDB is the answer.
NoSQL Database: Classification, Characteristics and ComparisonMayuree Srikulwong
My students' presentation of a paper "NoSQL Database: New Era of Databases for Big Data Analytics - Classification, Characteristics and Comparison" by Moniruzzaman, A.B.M. and Hossain, S.A. (2013).
The bulk of the NoSQL Technologies focus on achieving scale-out ability by building their architecture around a simple, distributed hash, key-value store. This works well for partitioning simple data, but in reality, your information models are not simple. As a result, you may have to build enormous layers of code to manage an explicit structure baked into the persistence tier. In this session, take a look at a NoSQL solution which allows you to store naturally clustered, richly linked object networks beneath your key partitioned roots. The result is that you do not have to write extensive code to deal with the physical structure in the persistence tier even when dealing with complex information models like predictive models, timeseries, recursive relations, compositions, etc. We will explore how such an implementation works in practice by looking at a case study of an advanced model analytics and visualization solution built on the clustered NoSQL database solution Versant Database Engine.
Limiting software architecture to the traditional ideas is not enough for today's challenges. This presentation shows additional tools and how problems like maintainability, reliability and usability can be solved.
Continuous Delivery solves many current challenges - but still adoption is limited. This talks shows reasons for this and how to overcome these problems.
Four Times Microservices - REST, Kubernetes, UI Integration, AsyncEberhard Wolff
How you can build microservices:
- REST with the Netflix stack (Eureka for Service Discovery, Ribbon for Load Balancing, Hystrix for Resilience, Zuul for Routing)
- REST with Consul for Services Discovery
- REST with Kubernetes
- UI integration with ESI (Edge Side Includes)
- UI integration on the client with JavaScript
- Async with Apache Kafka
- Async with HTTP + Atom
This presentation show several options how to implement microservices: the Netflix stack, Consul, and Kubernetes. Also integration options like REST and UI integration are covered.
There are many different deployment options - package managers, tools like Chef or Puppet, PaaS and orchestration tools. This presentation give an overview of these tools and approaches like idempotent installation or immutable server.

How to Split Your System into MicroservicesEberhard Wolff
Splitting a system into microservices is a challenging task. This talk shows how ideas like Bounded Context, migration scenarios and technical constraints can be used to build a microservice architecture. Held at WJAX 2016.
Microservices and Self-contained System to Scale AgileEberhard Wolff
Architectures like Microservices and Self-contained Systems provide a way to support agile processes and scale them. Held at JUG Saxony Day 2016 in Dresden.
Data Architecturen Not Just for MicroservicesEberhard Wolff
Microservices change the way data is handled and stored. This presentation shows how Bounded Context, Events, Event Sourcing and CQRS provide new approaches to handle data.
We assume software should contain no redundancies and that a clean architecture is the way to a maintainable system. Microservices challenge these assumptions. Keynote from Entwicklertage 2016 in Karlsruhe.
Nanoservices are smaller than Microservices. This presentation shows how technologies like Amazon Lambda, OSGi and Java EE can be used to enable such small services.
Microservices: Architecture to scale AgileEberhard Wolff
Microservices allow for scaling agile processes. This presentation shows what Microservices are, what agility is and introduces Self-contained Systems (SCS). Finally, it shows how SCS can help to scale agile processes.
Microservices, DevOps, Continuous Delivery – More Than Three BuzzwordsEberhard Wolff
Microservices, DevOps and Continuous Delivery are three hypes at the moment. This talk looks into the relationships between these three approaches and gives an idea how these approaches help to solve concrete problems. Held at Continuous Lifecycle 2015.

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!

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. NoSQL Is All About the Persistence Question
03.04.13 NoSQL aus Sicht eines Architekten
5. Key-Value Stores
Key Value
► Maps keys to values 42 Some
► Just a large globally available Map data
► i.e. not very powerful data model
► No complex queries or indices
► Just access by key
► Redis: Think cache + Persistence
► Riak: Think massive scale
03.04.13 NoSQL aus Sicht eines Architekten
6. Wide Column
XX
XX XX XX XX
► Add any "column" you like to a row XX XX XX
► Not key-value - "key-(column-value)” XX XX XX XX
XX XX XX XX
► Column families are like tables XX XX XX XX
► E.g. in the "Users" column family XX XX XX XX
XX XX
> "someuser" è ("username"è"someuser"), XX XX XX
("email" è"someuser@example.com") XX XX XX
XX XX XX
► Columns named: indexing possible XX XX XX XX
► So queries possible XX XX XX XX
XX xX XX XX XX
► Apache Cassandra
► Amazon SimpleDB
► Apache HBase
► All tuned for large data sets
03.04.13 NoSQL aus Sicht eines Architekten
7. Document Stores
► Aggregates are typically stored as "documents“ (key-value collection)
► JSON quite common
► No fixed schema
► Indexes possible
► Queries possible
> E.g. "find all baskets that contain the product 123"
► Still great horizontal scalability
► Relations might be modeled as links
► MongoDB, CouchDB
03.04.13 NoSQL aus Sicht eines Architekten
8. Graph
► Nodes with Properties
► Typed relationships with properties
► Ideal e.g. to model relations in a social network
► Easy to find number of followers, degree of relation etc.
► Hard to scale out
► Neo4j
03.04.13 NoSQL aus Sicht eines Architekten
9. NoSQL Benefits
Costs
• Scale out instead of Scale Up
• Cheap Hardware Ops
• Usually Open Source
Flexibility
• Schema in code not in
database
• Easier to upgrade schema
Dev • Easier to handle
heterogeneous data
No Object/relational impedance mismatch
• NoSQL database are more OO like

12. Document-oriented databases
► Offer scale out
> Unless you need huge amounts of data Cost
► Offer a rich and flexible data model Flexibility

► Other databases have other sweet spots
> Huge data sets
> Graph structures
> Analyzing data
► Niches or mainstream?

16. This is not how
Software Architecture works.
03.04.13 NoSQL aus Sicht eines Architekten
17. Why not?
More is worse!
More hardware More Ops Trouble
• Installation
• Backup
More Developer Skillz • Disaster Recovery
Not necessarily bad • Monitoring
• Optimizations
03.04.13 NoSQL aus Sicht eines Architekten
18. But: Polyglott Persistence Has a Point
Object-oriented Databases did it wrong
• Strategy: Replace RDBMS
• Enterprises will stick to RDBMS
• Pure technology migration basically
never happens
• …only vendors think differently
Example: Archive Database
• Store current data in RDBMS
• Store archive in NoSQL (MongoDB)
• Archive contains mainframe data
• Benefit: Use flexibility to allow for many data formats
• Benefit: No need to convert mainframe data
• Benefit: Store lots of data cheaply
03.04.13 NoSQL aus Sicht eines Architekten
19. Complex Document Processing System
elastic
MongoDB Redis
search
Document- Key/value
Search
oriented in memory
engine
Documents Meta Data for
quick access Search
index
04.04.13 NoSQL aus Sicht eines Architekten
20. Alternative: Only elasticsearch
elastic
• Stores original documents as well search
• (like a key/value store)
• Support for complex queries
• Very powerful features also for data
mining / analytics
04.04.13 NoSQL aus Sicht eines Architekten
21. Alternative: Only MongoDB
MongoDB
• Now with (limited beta) fulltext search
• Quite fast – memory mapped files
• So why Redis?
• Map/Reduce support
04.04.13 NoSQL aus Sicht eines Architekten
22. What about Redis?
Redis
• Like a Swiss Knife
• Cache
• Messaging
• Central coordination in a distributed
environment

Developer / Architect DBA
► Schema design (at least partly) ► Performance tuning
► Access code ► Indices
► Query optimization
► Changes do not influence code
