What is GraphDB and how can it help you run a smart data-driven business?
Learn about GraphDB through the solutions it offers in a simple and easy to understand way. In the slides below we have unpacked GraphDB for you, using as little tech talk as possible.
In next 3-5 year this technology will play a major role because data is growing in uncontrolled way like data generated from intelligent systems,social networks ,mobile phones leads and in last 5 years that generation has doubled and this leads to big data .
big data has 3 characteristics calles 3v's that is
velocity of data.

Big data problem is solved by hadoop which uses hadoop file distribution system(provides huge storage in distributed form) and through map reduce framework it solves the need of high computing power.
Despite the existence of data analysis tools such as R, SQL, Excel and others, it is still insufficient to cope with today's big data analysis needs.
The author proposes a CUI (Character User Interface) toolset with dozens of functions to neatly handle tabular data in TSV (Tab Separated Values) files.
It implements many basic and useful functions that have not been implemented in existing software with each function borrowing the ideas of Unix philosophy and covering the most frequent pre-analysis tasks during the initial exploratory stage of data analysis projects.
Also, it greatly speeds up basic analysis tasks, such as drawing cross tables, Venn diagrams, etc., while existing software inevitably requires rather complicated programming and debugging processes for even these basic tasks.
Here, tabular data mainly means TSV (Tab-Separated Values) files as well as other CSV (Comma Separated Value)-type files which are all widely used for storing data and suitable for data analysis.

Adjusting OpenMP PageRank : SHORT REPORT / NOTESSubhajit Sahu
For massive graphs that fit in RAM, but not in GPU memory, it is possible to take
advantage of a shared memory system with multiple CPUs, each with multiple cores, to
accelerate pagerank computation. If the NUMA architecture of the system is properly taken
into account with good vertex partitioning, the speedup can be significant. To take steps in
this direction, experiments are conducted to implement pagerank in OpenMP using two
different approaches, uniform and hybrid. The uniform approach runs all primitives required
for pagerank in OpenMP mode (with multiple threads). On the other hand, the hybrid
approach runs certain primitives in sequential mode (i.e., sumAt, multiply).
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.

What is big data?
How big it is...?
Data generated by us
Real time example

3. WHAT IS BIG DATA ?
Big Data is nothing but a size of a data.
Data with large volume.
Collection of data sets of large that
is difficult to process .

4. HOW BIG IT IS!!
Byte - one seed
Kilobyte - a cup of seed
Megabyte - 8 bags of seed
Gigabyte - 3 trucks of seed
Terabyte - 2 ships of seed
Petabyte - whole volume of our India
Exabyte - volume of Asian continent
Zettabyte - fills our Indian ocean

6. DATA GENERATED BY US
There are 2.5 quintillion bytes of data created each day
Google now processes more than 40,000 searches EVERY
second (3.5 billion searches per day)!
There are five new Facebook profiles created every
second!
Every minute there are 510,000 comments posted and
293,000 statuses updated
95 million photos and videos are uploaded on face book
per day. 6
7. TECHNOLOGY
Big data always brings a number of challenges..
80% of datum are unstructured .
how to structured that datum and
how to analyze and store the datum.
the top technologies used to store and analyse Big Data are
Hadoop
NoSql
Hive
Sqoop 7
8. HADOOP
Developed by apache software development
It is a framework. Developed by java.
This framework runs on a cluster and has an ability to
allow us to process data across all nodes.
Hadoop distributed file system - storage system of
hadoop
HDFS splits the data and distribute among different
nodes in clusters. 8
9. NOSQL
Not only sql
NoSQL (Not Only SQL) to handles unstructured data.
NoSQL databases store unstructured data with no particular schema
NoSQL gives better performance in storing very big amount of data.
Other free NoSQL open source database are
Mongodb
Couchdb
Hbase
Perst
casandra 9
10. Hive
This is a distributed data management for Hadoop.
It is like SQL query option HiveSQL (HSQL) to access big data.
This can be primarily used for Data mining purpose.
This runs on top of Hadoop.
Sqoop
This tool connects Hadoop with various relational databases to
transfer data.
used to transfer structured data to Hadoop or Hive.
10
12. Volume
size of the data content generated that needs to be analyzed.
Velocity
speed at which new data is generated, and the speed at which
data moves.
Value
meaningful outpu
worth of the data being extracted.
Having endless amounts of data is one thing, but unless it can be
turned into value it is useless.
12
13. Variety
types of data that can be analyzed. previously we use rdbms it is
a structured data so we can easily analyse the data. but now a day
80% of data are unstructured big data technology is now
allowing structured and unstructured data to be collected, stored,
and used simultaneously.
Veracity
trustworthiness of the data Just how accurate is all this data?
13
21. CONCLUSION
Companies are turning to Big Data in order to expand into new
markets and improve customer relations .
The use of analytics can improve the industry knowledge of the
analysts.
There are huge requirements of big data analytics in different fields
and industries.
So the role of big data in present IT world is very desirable.
