This document discusses big data, where it comes from, and how it is processed and analyzed. It notes that everything we do online now leaves a digital trace as data. This "big data" includes huge volumes of structured, semi-structured, and unstructured data from various sources like social media, sensors, and the internet of things. Traditional computing cannot handle such large datasets, so technologies like MapReduce, Hadoop, HDFS, and NoSQL databases were developed to distribute the work across clusters of machines and process the data in parallel.
Detailed description of big data, with the characteristics of it. What are the limitations of the traditional systems? Where we are using big data? And also the applications of big data.
Big Stream Processing Systems, Big GraphsPetr Novotný
Big Data, a recent phenomenon. Everyone talks about it, but do you really know what Big Data is? Join our four-part series about Big Data and you will get answers to your questions!
We will cover Introduction to Big Data and available platforms which we can use to deal with Big Data. And in the end, we are going to give you an insight into the possible future of dealing with Big Data.
After the two previous episodes you know the basics about Big Data. Yet, it might get a bit more complicated than that. Usually when you have to deal with data which is generated in real-time. In this case, you are dealing with Big Stream.
This episode of our series will be focussed on processing systems capable of dealing with Big Streams. But analysing data lacking graphical representation will not be very convenient for us. And this is where we have to use a platform capable of visualising Big Graphs. All these topics will be covered in today’s presentation.

Bigdata.
Big data is a term for data sets that are so large or complex that traditional data processing application software is inadequate to deal with them. Challenges include capture, storage, analysis, data curation, search, sharing, transfer, visualization, querying, updating and information privacy. The term "big data" often refers simply to the use of predictive analytics, user behavior analytics, or certain other advanced data analytics methods that extract value from data, and seldom to a particular size of data set. "There is little doubt that the quantities of data now available are indeed large, but that’s not the most relevant characteristic of this new data ecosystem."[2] Analysis of data sets can find new correlations to "spot business trends, prevent diseases, combat crime and so on."[3] Scientists, business executives, practitioners of medicine, advertising and governments alike regularly meet difficulties with large data-sets in areas including Internet search, fintech, urban informatics, and business informatics. Scientists encounter limitations in e-Science work, including meteorology, genomics,[4] connectomics, complex physics simulations, biology and environmental research.[5]
Data sets grow rapidly - in part because they are increasingly gathered by cheap and numerous information-sensing Internet of things devices such as mobile devices, aerial (remote sensing), software logs, cameras, microphones, radio-frequency identification (RFID) readers and wireless sensor networks.[6][7] The world's technological per-capita capacity to store information has roughly doubled every 40 months since the 1980s;[8] as of 2012, every day 2.5 exabytes (2.5×1018) of data are generated.[9] One question for large enterprises is determining who should own big-data initiatives that affect the entire organization.[10]
Relational database management systems and desktop statistics- and visualization-packages often have difficulty handling big data. The work may require "massively parallel software running on tens, hundreds, or even thousands of servers".[11] What counts as "big data" varies depending on the capabilities of the users and their tools, and expanding capabilities make big data a moving target. "For some organizations, facing hundreds of gigabytes of data for the first time may trigger a need to reconsider data management options. For others, it may take tens or hundreds of terabytes before data size becomes a significant consideration."
It is a brief overview of Big Data. It contains History, Applications and Characteristics on BIg Data.
It also includes some concepts on Hadoop.
It also gives the statistics of big data and impact of it all over the world.
Introduction to Big Data (non-technical) and the importance of Data Science to create meaning.
First of all we define Big Data in the light of the 3 Vs: volume, velocity and variety; next we move on to redefine Big Data, and we touch the topic of a data lake. We envision that Big Data will become mainstream for small organisations as well, what we can do with Big Data, how to tackle Big Data projects, what challenges lie ahead, but what opportunities are there to reap. And of course how important data science is to find the meaning in all the data.

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.
Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.

Activity Listening music, reading a book, searching, shopping, etc.
Our conversations in social media are now digitally recorded.Conversation
We upload and share 100s of thousands of them on social media
sites every second.
Photo and Video
We are increasingly surrounded by sensors that collect and share
data.

We now have smart TVs that are able to collect and process data.The Internet of Things
4. The basic idea behind the phrase
'Big Data' is that everything we
do is increasingly leaving a digital
trace (or data), which we (and
others) can use and analyse
5. Big data :
means really a big data, it is
a collection of large
datasets that cannot be
processed using traditional
computing techniques.
6. Big Data includes huge volume, high velocity,
and extensible variety of data.

8. Big Data Technologies
Operational Big Data
This include systems like MongoDB that
provide operational capabilities for real-
time, interactive workloads where data is
primarily captured and stored.
NoSQL Big Data systems are designed to
allow massive computations to be run
inexpensively and efficiently. This makes
operational big data workloads much
easier to manage, cheaper, and faster to
implement.
Analytical Big Data
This includes systems like Massively
Parallel Processing (MPP) database
systems and MapReduce that provide
analytical capabilities for retrospective
and complex analysis.
A system based on MapReduce can be
scaled up from single servers to
thousands of high and low end machines.
10. Traditional Approach
In this approach, an enterprise will have a
computer to store and process big data. Here
data will be stored in an RDBMS, process the
required data and present it to the users for
analysis purpose. tutorialspoint.com
11. Google’s
Solution
Google solved this problem using an
algorithm called MapReduce. This
algorithm divides the task into small
parts and assigns those parts to
many computers connected over
the network, and collects the results
to form the final result dataset.

12. Hadoop
Hadoop runs applications using the
MapReduce algorithm, where the
data is processed in parallel on
different CPU nodes. In short,
Hadoop framework is capable
enough to develop applications,
capable of running on clusters of
computers and they could perform
complete statistical analysis for a
huge amounts of data.

Perkembangan teknologi, alat, dan media komunikasi yang semakin pesat, berbanding lurus dengan jumlah data yang dihasilkan oleh umat manusia. Dari awal terbentuknya bumi sampai 2003, ketika bilik-bilik warnet masih sepi, dan internet masih benda asing, data yang dihasilkan umat manusia itu sebanyak 5 milliar GB. Kemudian di tahun-tahun berikutnya, muncul friendster, facebook, twitter, pun perangkat baru mulai bermunculan seperti ipod, nokia yang dibekali dengan gprs sehingga umat manusia mulai menggunakan internet.
Delapan tahun berlalu, blackberry mulai booming, disertai dengan whatsapp, twitter, dan dalam 2 hari mampu memproduksi 5 milyar GB meskipun untuk paketan internet saat itu masih eman-eman. Android pun mulai menjamur beberapa tahun sesudahnya, pengguna pun mulai banyak, umat manusia sudah mulai terbiasa dengan paketan internet dan akhirnya data sebanyak 5 milyar GB dapat diproduksi dalam eaktu 10 menit.
Simple activities like listening to music or reading a book are now generating data. Digital music players and eBooks collect data on our activities. Your smart phone collects data on how you use it and your web browser collects information on what you are searching for. Your credit card company collects data on where you shop and your shop collects data on what you buy. It is hard to imagine any activity that does not generate data.
Our conversations are now digitally recorded. It all started with emails but nowadays most of our conversations leave a digital trail. Just think of all the conversations we have on social media sites like Facebook or Twitter. Even many of our phone conversations are now digitally recorded.
Just think about all the pictures we take on our smart phones or digital cameras. We upload and share 100s of thousands of them on social media sites every second. The increasing amounts of CCTV cameras take video images and we up-load hundreds of hours of video images to YouTube and other sites every minute .
We are increasingly surrounded by sensors that collect and share data. Take your smart phone, it contains a global positioning sensor to track exactly where you are every second of the day, it includes an accelometer to track the speed and direction at which you are travelling. We now have sensors in many devices and products.
We now have smart TVs that are able to collect and process data, we have smart watches, smart fridges, and smart alarms. The Internet of Things, or Internet of Everything connects these devices so that e.g. the traffic sensors on the road send data to your alarm clock which will wake you up earlier than planned because the blocked road means you have to leave earlier to make your 9am meeting…
Volume refers to the vast amounts of data generated every second. We are not talking Terabytes but Zettabytes or Brontobytes. If we take all the data generated in the world between the beginning of time and 2008, the same amount of data will soon be generated every minute. New big data tools use distributed systems so that we can store and analyse data across databases that are dotted around anywhere in the world.
Velocity refers to the speed at which new data is generated and the speed at which data moves around. Just think of social media messages going viral in seconds. Technology allows us now to analyse the data while it is being generated (sometimes referred to as in-memory analytics), without ever putting it into databases.
Variety refers to the different types of data we can now use. In the past we only focused on structured data that neatly fitted into tables or relational databases, such as financial data. In fact, 80% of the world’s data is unstructured (text, images, video, voice, etc.) With big data technology we can now analyse and bring together data of different types such as messages, social media conversations, photos, sensor data, video or voice recordings.
Limitation :
This approach works well where we have less volume of data that can be accommodated by standard database servers, or up to the limit of the processor which is processing the data. But when it comes to dealing with huge amounts of data, it is really a tedious task to process such data through a traditional database server.
