Overview of SQL vs NoSQL. When to use NoSQL vs structured databases. Shows roadmap and considerations for defining success of implementation of Big Data in the enterprise. This presentation also provides a quick overview of the different types of Big-Data databases
SQL vs. NoSQL. It's always a hard choice.Denis Reznik
This will be an interesting and sometimes fun session with a small demo. This session will answer some of your questions and force you to think about new questions. It will not be very technical, so it's ok for choose another more technical session from the schedule :) But if will decide to come, I can assure you, that you will not be disappointed. We will do a thought experiment with one famous public high-loaded website, will look at advantages and disadvantages of SQL and NoSQL databases, and will choose the best database engine for it.
Если раньше при старте нового проекта нам нужно было выбрать одну из доступных на тот момент SQL баз данных, то за последние 5 лет ситуация кардинально изменилась. Теперь выбор стал гораздо сложнее. SQL или NoSQL? Сloud или on-premises? Если SQL/NoSQL - то какая именно? А может использовать и то и другое?
В данном докладе мы постараемся представить общий обзор доступных сегодня решений для хранения данных и определиться с критериями выбора.
NoSQL, as many of you may already know, is basically a database used to manage huge sets of unstructured data, where in the data is not stored in tabular relations like relational databases. Most of the currently existing Relational Databases have failed in solving some of the complex modern problems like:
• Continuously changing nature of data - structured, semi-structured, unstructured and polymorphic data.
• Applications now serve millions of users in different geo-locations, in different timezones and have to be up and running all the time, with data integrity maintained
• Applications are becoming more distributed with many moving towards cloud computing.
NoSQL plays a vital role in an enterprise application which needs to access and analyze a massive set of data that is being made available on multiple virtual servers (remote based) in the cloud infrastructure and mainly when the data set is not structured. Hence, the NoSQL database is designed to overcome the Performance, Scalability, Data Modelling and Distribution limitations that are seen in the Relational Databases.

Analysis and evaluation of riak kv cluster environment using basho benchStevenChike
Many institutions and companies with technological development have been producing large size of structured and unstructured data. Therefore, we need special databases to deal with these data and thus emerged NoSQL databases. They are widely used in the cloud databases and the distributed systems. In the era of big data, those databases provide a scalable high availability solution. So we need new architectures to try to meet the need to store more and more different kinds of different data. In order to arrive at a good structure of large and diverse data, this structure must be tested and analyzed in depth with the use of different benchmark tools. In this paper, we experiment the Riak key-value database to measure their performance in terms of throughput and latency, where huge amounts of data are stored and retrieved in different sizes in a distributed database environment. Throughput and latency of the NoSQL database over different types of experiments and different sizes of data are compared and then results were discussed.
Mankind has stored more than 295 billion gigabytes (or 295 Exabyte) of data since 1986, as per a report by the University of Southern California. Storing and monitoring this data in widely distributed environments for 24/7 is a huge task for global service organizations. These datasets require high processing power which can’t be offered by traditional databases as they are stored in an unstructured format. Although one can use Map Reduce paradigm to solve this problem using java based Hadoop, it cannot provide us with maximum functionality. Drawbacks can be overcome using Hadoop-streaming techniques that allow users to define non-java executable for processing this datasets. This paper proposes a THESAURUS model which allows a faster and easier version of business analysis.
Asterix Solution’s Hadoop Training is designed to help applications scale up from single servers to thousands of machines. With the rate at which memory cost decreased the processing speed of data never increased and hence loading the large set of data is still a big headache and here comes Hadoop as the solution for it.

Big data analytics: Technology's bleeding edgeBhavya Gulati
There can be data without information , but there can not be information without data.
Companies without Big Data Analytics are deaf and dumb , mere wanderers on web.
With many organisations considering getting on the Hadoop bandwagon, this document provides an overview of the planned use cases for Hadoop, an illustration of some of the common technology components, suggestions on when Hadoop is worth considering, some the challenges organisations are experiencing, cost considerations and finally, how an organisation should position for a Big Data initiative. Any organisation considering a Big Data initiative with Hadoop should thoroughly consider each of these areas before embarking on a course of action.

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

Data Centers - Striving Within A Narrow Range - Research Report - MCG - May 2...pchutichetpong
M Capital Group (“MCG”) expects to see demand and the changing evolution of supply, facilitated through institutional investment rotation out of offices and into work from home (“WFH”), while the ever-expanding need for data storage as global internet usage expands, with experts predicting 5.3 billion users by 2023. These market factors will be underpinned by technological changes, such as progressing cloud services and edge sites, allowing the industry to see strong expected annual growth of 13% over the next 4 years.
Whilst competitive headwinds remain, represented through the recent second bankruptcy filing of Sungard, which blames “COVID-19 and other macroeconomic trends including delayed customer spending decisions, insourcing and reductions in IT spending, energy inflation and reduction in demand for certain services”, the industry has seen key adjustments, where MCG believes that engineering cost management and technological innovation will be paramount to success.
MCG reports that the more favorable market conditions expected over the next few years, helped by the winding down of pandemic restrictions and a hybrid working environment will be driving market momentum forward. The continuous injection of capital by alternative investment firms, as well as the growing infrastructural investment from cloud service providers and social media companies, whose revenues are expected to grow over 3.6x larger by value in 2026, will likely help propel center provision and innovation. These factors paint a promising picture for the industry players that offset rising input costs and adapt to new technologies.
According to M Capital Group: “Specifically, the long-term cost-saving opportunities available from the rise of remote managing will likely aid value growth for the industry. Through margin optimization and further availability of capital for reinvestment, strong players will maintain their competitive foothold, while weaker players exit the market to balance supply and demand.”
SQL vs NoSQL: Big Data Adoption & Success in the Enterprise
1. SQL & No-SQL (Hadoop?)
- Big Data Adoption & Success in the
Enterprise
- By Anita Luthra 2016
2. MYTHS ABOUT HADOOP
Myth Actual
Hadoop Is A Single Product Hadoop is an ecosystem, not a single product
Apache Hadoop open
source
Multiple vendors have implementations of
Hadoop as well to add usability tools, ease of
use functionality
Hadoop is a Data
management system
Hadoop is actually file-system based
Hive resembles SQL Is not standard SQL. Instead, Hadoop uses
Apache Hive and HiveQL, a SQL-like language
Hadoop requires
MapReduce
Hadoop can survive by itself. They complement
each but are not required
3. MYTHS ABOUT HADOOP - II
Myth Actual
Hadoop and Big Data are
synonymous
Hadoop isn’t the only answer. products
from Teradata, Sybase IQ (now owned by
SAP) and Vertica (now owned by
Hewlett-Packard).
Hadoop is used for Data
Volume
Hadoop is for data diversity, not just data
volume. Go back to the V3 or V4 (Volume,
Variety, Velocity, Veracity)
Hadoop replaces the Data
Warehouse
It is a complement to the data
warehouse, another tool in the arsenal,
not a replacement
Hadoop is for Web
Analytics
Hadoop enables many types of analytics,
not just Web analytics
Big Data Requires Hadoop Big data does not require Hadoop, there
4. SQL DATABASES & NOSQL
Traditional OLAP/OLTP Limitations:
1. E.g., A structured database needs to know what is
being stored in advance.
2. The Agile development approach does not work well.
Each time new features are added, the schema of the
database requires changes.
3. If the database is large, the process is slow.
4. Rapid iterations and frequent data changes result in
frequent downtime.
5. SQL VS. NOSQL
5. Relational databases are not designed to cope
with the scale and agility challenges of modern
applications. They are not built to take advantage
of today’s available cheap storage and
processing power.
6. NOSQL ADVANTAGES
1. NoSQL databases allow insertion of data without a
predefined schema.
2. Application changes in real-time are easier, resulting in
faster development.
3. Code integration is more reliable, and less database
administration is needed.
4. NoSQL provides the ability to handle a variety of
database technologies. It was developed in response
to handling volume of data, frequency in which this
data is accessed, performance and processing needs.
7. NO-SQL ADVANTAGES - II
5. NoSQL databases are more scalable and provide superior
performance. The data model addresses issues not addressed
by traditional relational model databases such as:
Ability to handle large volumes of structured, semi-
structured, and unstructured data
Ability to handle Agile sprints, quick iterations, and
frequent code pushes
Object-oriented programming that is easy to use and
flexible
Efficient, scale-out architecture instead of expensive,
monolithic architecture.
8. WHEN TO USE BIG DATA TOOLING
Users want to interact with their data: totality, exploration,
and frequency. Totality refers to the increased desire to
process and analyze all available data, rather than
analyzing a sample of data and extrapolating the results.
However:
Apache Hadoop does not replace the data warehouse
and NoSQL databases do not replace transactional
relational databases.
Neither do MapReduce, nor streaming analytics Hive—
Apache’s data warehousing application is used to query
Hadoop data stores
10. SAMPLE TOOLING USAGE -- MONGODB
Boxed Ice is an example of a company working with big data
technology— a NoSQL database called MongoDB.
Headquartered in London, Boxed Ice offers a hosted software
product called Server Density that monitors the health of cloud
computing deployments, servers and websites for about 1,000
clients around the globe—a task that requires copious
amounts of data processing.
“We monitor quite a few websites and servers for customers
like EA, Intel and The New York Times,” said David Mytton,
Boxed Ice’s CEO and founder. “We are processing about 12
terabytes of data every month with MongoDB, and that
equates to about 1 billion documents each month.”
11. ZION’S BANCORPORATION SOLUTION
Zion’s Bancorporation (Zion’s), launched a fraud analytics
program nine years ago. Cracking the big data code is a moving
target requiring advanced technology and keen intellect.
Problem Statement
1. With exponential growth of data volume over the last decade, finding
needles of useful information in haystacks of data was a formidable task.
2. Data needed to be captured while in motion, in order to be truly effective.
Solution Approach
Used to handle “big data” challenge for fraud analytics: Zion used non-
traditional data tools such as Hadoop, NoSQL Database, MapReduce for
Analytics, for defining big data computing.
Outcome
Zion’s bank fraud and security analytics team has continually built and refined
statistical models that have helped bank executivespredict, identify,evaluate
and, when necessary, react to suspicious activity

13. WHY DIFFERENT TYPES OF NOSQL DATABASES?
1. CAP theorem, aka Brewer's Theorem.
You can provide only two out of the following three
characteristics: consistency, availability, and partition
tolerance.
Different datasets and different runtime rules require trade-offs.
Different database technologies focus on different trade-offs.
The complexity of the data and the scalability of the system also
come into play.
2. Basic computer science or even more basic mathematics.
Some datasets can be mapped easily to key-value pairs.
I.e., Flattening the data does not make it less meaningful. No
reconstruction of relationships is necessary.
3. There are datasets where the relationship to other items of
data is as important as the items of data themselves.
15. NO-SQL (AGGREGATE) DATA MODEL: KEY VALUE
Key Value are the simplest NoSQL databases. Every item in the
database is stored as an attribute name (or "key"), together with
its value. Some key-value stores, such as Redis, allow each value
to have a type, such as "integer", which adds functionality.
16. NO-SQL (AGGREGATE) DATA MODEL: DOCUMENT
Pairs each key with a complex data structure known as a
document. Documents can contain many different key-value
pairs, key-array pairs, or even nested documents.
17. NO-SQL (AGGREGATE) DATA MODEL: COLUMN N FAMILY
Wide-Column stores are optimized for queries over large datasets, and store
columns of data together, instead of rows. A hash map crossed with a
multidimensional array. Each column contains a row of data ...
Eg., Row
Key,
Grouped by
a row key, a
customer
profile, and
orders for
the
customer
18. NO-SQL DATA MODEL: GRAPH STORES
Complex inter-relationships
Not easily handled in multi-
table joins
This model is very good for
managing across relationships.
Very good at moving across
relationships between things.
Just like SQL databases, Graph
databases do ACID.
Other noSQL data models do
not use the ACID concept,
however, Graph databases do.
Used to store information about networks, such as social
connections. Graph stores include Neo4J and HyperGraphDB.
Outlier.
19. GRAPH DATABASES - EXPLAINED
Graph databases are based on graph
theory. Graph databases employ
nodes, properties, and edges.
Nodes represent entities such as people,
businesses, accounts, or any other item
you might want to keep track of.
Properties -- relate to nodes. E.g.,
"Wikipedia" as one of the nodes, might
tie to properties such as "website",
"reference material", or "word that starts
with the letter 'w'", depending on
aspects of "Wikipedia" pertinent to the
particular database.25
23. DEFINING SUCCESS IN A BIG DATA PROGRAM
According to Zions and others who use
Hadoop, NoSQL databases and similar tools
that have come to define the era of big data
computing.
Achieving a great return on investment (ROI)
is about
1. Creating the right team
2. Putting a solid business strategy in place
3. Being agile and testing—lots and lots of testing
24. BIG DATA – WHAT DEFINES SUCCESS II
1. Organizations evaluating big data technologies should
remember to test them in conjunction with their own
data sets or applications, as opposed to using some
arbitrary data set or app a salesperson has on hand.
2. Getting a Big Data environment to work right requires
testing, tuning, keeping up with documentation and
paying attention to what the open source community
has to say.
3. With the right team and strategy in place, big data
technologies like Hadoop, Hive, Pig, Cassandra,
Mahout and others can open up a world of predictive
possibilities
