The awesome points to learn from DB2 NoSQL GraphStore

One best example, prior to understanding the RDF format for Graph data model- If the graph data model is the model the semantic web uses to store data, RDF is the format in which it is written. 
Related: Highly Demanding Web Designer Jobs
Summary of DB2 Graph Store: DB2-RDF support is officially called "NoSQL Graph Support".  The API extends the Jena API (Graph layer).  Developers familiar with Jena TDB will have the Model layer capabilities they are accustomed to.Although the DB2-RDF functionality is being released with DB2 LUW 10.1, it is also compatible with DB2 9.7.Full supports for SPARQL 1.0 and a subset of SPARQL 1.1.  Full SPARQL 1.1 support (which is till a W3C working draft) will be forthcoming.While RDBMS implementations of RDF graphs have typically been non-performant, that is not the case here*.  Some very impressive and innovative work has been put into optimization capabilities.  Out-of-the box performance is comparable with native triple stores, and read/write p…

Scrum Vs Agile Methodology best explained with more details

Scrum is part of the Agile movement. Agile is a response to the failure of the dominant software development project management paradigms (including waterfall) and borrows many principles from lean manufacturing. In 2001, 17 pioneers of similar methods met at the Snowbird Ski Resort in Utah and wrote the Agile Manifesto, a declaration of four values and twelve principles. 
These values and principles stand in stark contrast to the traditional Project Manager’s Body Of Knowledge (PMBOK). The Agile Manifesto placed a new emphasis on communication and collaboration, functioning software, team self organization, and the flexibility to adapt to emerging business realities.

How Does Scrum Fit With Agile? The Agile Manifesto doesn’t provide concrete steps. Organizations usually seek more specific methods within the Agile movement. These include Crystal Clear, Extreme Programming, Feature Driven Development, Dynamic Systems Develo…

Tableau top features useful for data analysis

Tableau is one of the most popular tool in data analysis. Learning the Tableau gives you so many options in data analysis career.

You can download Tableau Software free version here. Get complete understanding document on how Tableau works here. Read this post for advancing in your Tableau Career.

Unique functionality in Tableau: Tableau Software was founded on the idea that analysis and visualization should not be isolated activities but must be synergistically integrated into a visual analysis process. Visual analysis means specifically:
Data Exploration. Visual analysis is designed to support analytical reasoning. The goal of visual analysis is to answer important questions using data and facts. In order to support analysis, it is not enough to only access and report on the data. Analysis requires computational support throughout the process. Typical steps in analysis include such operations as (1) filtering to focus on items of interest, (2) sorting to rank and prioritize, (3) grou…

The big revelution of Indutrial Internet of Things

To understand why General Electric is plowing $1 billion into the idea of using software to transform industry, put yourself in the shoes of Jeff Immelt, its CEO. As recently as 2004, GE had reigned as the most valuable company on the planet. But these days, it’s not even the largest in America. Apple, Microsoft, and Google are all bigger. Software is king of the hill. And,as Immelt came to realize, GE is not that great at software.Internal surveys had discovered that GE sold $4 billion worth of industrial software a year—the kind used to run pumps or monitor wind turbines.

That’s as much as the total revenue of Salesforce.com. But these efforts were scattered and not always state-of-the-art. And that gap was turning dangerous. GE had always believed that since it knew the materials and the physics of its jet engines and medical scanners, no one could best it in understanding those machines. But companies that specialize in analytics, like IBM, were increasingly spooking GE by figuri…

Top Daily Use LINUX Commands for Programmers

1.1 What is a command shell?
A program that interprets commands Allows a user to execute commands by typing them manually at a terminal, or automatically in programs called shell scripts. A shell is not an operating system. It is a way to interface with the operating system and run commands.

1.2 What is BASH?
BASH = Bourne Again SHell
Bash is a shell written as a free replacement to the standard Bourne Shell (/bin/sh) originally written by Steve Bourne for UNIX systems. It has all of the features of the original Bourne Shell, plus additions that make it easier to program with and use from the command line. Since it is Free Software, it has been adopted as the default shell on most Linux systems.

1.3 How is BASH different from the DOS command prompt?
Case Sensitivity: In Linux/UNIX, commands and filenames are case sensitive, meaning that typing “EXIT” instead of the proper “exit” is a mistake.
“\” vs. “/”: In DOS, the forward-slash “/” is the command argument delimiter, while the backslas…

IT Jobs on Internet of Things - Best Group

All freshers and experienced software developers can join in this group who wish to take their career on Internet-of-things(IoT)
IT JOBS on Internet of Things - Join Today to get benefit.

Imagine a world where billions of objects can sense, communicate and share information, all
interconnected over public or private Internet Protocol (IP) networks. These interconnected
objects have data regularly collected, analysed and used to initiate action, providing a
wealth of intelligence for planning, management and decision making. This is the world of
the Internet of Things (IOT).

The IOT concept was coined by a member of the Radio Frequency Identification (RFID)
development community in 1999, and it has recently become more relevant to the practical
world largely because of the growth of mobile devices, embedded and ubiquitous
communication, cloud computing and data analytics.

Top advantages of Agile Project Management vs Waterfall model

The Agile Project Management has its roots in the iterative project management. The Agile project management is highly flexible and interactive model where the requirements and resultant plan to meet those requirements keeps changing with inputs from stakeholders, suppliers and customers.

The traditional practice of project management, often referred to as “waterfall” project management suffers from various drawbacks, especially when it came to meeting the needs of complex projects where the requirements cannot be stated fully till the time a prototype is developed or on wider projects where there are multiple facets of the product being produced. In addition, when planning happens much in advance, there are chances that requirements may change by the time project comes to closing phase rendering the product ineffective or partially effective. Compare this to a project where one module is developed in short period of time (may be 2–3 weeks), is implemented, feedback taken from users,…

Role of 'Information Architect' in an Enterprise

Gartner defines "enterprise information architecture" as that part of the enterprise architecture process that describes — through a set of requirements, principles and models — the current state, future state, and guidance necessary to flexibly share and exchange information assets to achieve effective enterprise change. Also called EIA - Enterprise information Architect.

The transition from information that is isolated within applications to a flexible, comprehensive enterprise information architecture will require changes in technology, process, organizational structure and orientation.
In particular, EA practitioners comfortable with technical architecture must now devote time to understanding this emerging discipline. 

Gartner projects that, EA teams will be forced by the business to spend as much time on information
architecture as they currently spend on technical architecture. Changes will also impact a range of disciplines across the organization and will require co…
