Cassandra – An Approach towards NOSQL DB systems

Apache Cassandra Database is highly scalable and available platform for distributed database systems with no single point of failure.It is employed in commodity servers that deal with large sets of structured data. It is free, open-source (source code can be changed at any point of time) and possesseslower latency making it survive regional outages. It is driving many of today’s modern application businesses.

Cassandra serves both real-time operational store database (online transactional applications) and read-intensive database (large scale Business Intelligence system). It does not support a fully relational data model, instead, it supports a simple data model with dynamic control of data layout and format.

Cassandra is flexible in its data storage as it stores all kinds of unstructured, semi-structured and structured data across data centers as well as cloud. Changes to this data can be updated as per the need. Cassandra ensures strong security and also lowers Total Cost of Ownership (TCO).

Some of the key points include:

  • Cassandra is consistent and fault-tolerant
  • Its database is column-oriented
  • Created on Facebook, it completely differs from RDBMS
  • Successfully employed and deployed by some of the notable enterprises like Twitter, Netflix, Cisco, eBay, etc.,
  • Its design is inspired from Amazon’s Dynamo, and
  • Its data model is inspired from Google’s Bigtable so that it avails maximum flexibility with quick response time.
  • It supports simple transactions with both read and write scalability.
  • Cassandra Query Language (CQL, just like SQL) moves any kind of RDBMS to Cassandra.

Tools like nodetool (command line management) and Cassandra-stress (load-stressing a basic benchmarking) are installed in Cassandra by default. Cassandra supports numerous language drivers so that any kind of applications can run optimally, be it: Python, Ruby, Java, C++, etc.,

Architecture Explained

Cassandra architecture is designed keeping in mind the fact that “system hardware errors can and do occur”. The architecture is distributed and data is placed on different machines. It is a type of NoSQL database, but Cassandra’s architecture is forefront, making it even outperform NoSQL alternatives in real applications. Its architecture is built-for-scale, which means it can handle petabytes of information and thousands of operations per second, independent of special hardware or software.

Cassandra runs on a single daemon. To run a program, there is no need of a complex set of configuration, locking, and other services.It is far from the legacy concept of “master” node, and all nodes are identical and communicate equally with each other. Its design is in the form of a “masterless” ring with the multi-master approach, that is easy to setup and maintain.


Here the circled numbers in red represent nodes, whereas the interlinking in blue represents distributed architecture. In the image above, the client is sending data to the various nodes present in its architecture. Operation and scale out are simple and none of the nodes havea special role.

Cassandra complementing Hadoop

Apache Cassandra is complementing Hadoop as it comes out as a perfect choice for online Web and Mobile applications and has a batch-oriented data warehouse environment which aids processing of colder data for the purpose of analytics.This enables any IT Organization to effectively support analytic “tempos” required for the efficient run of business.

Career Opportunities

Apache Cassandra Developers develop and work on projects. They also develop applications that leverage on databases.Cassandra training helps both the Administrator or Architectwith knowledge on the latest advancements in Cassandra and you can land in a decent job if you are a fresher seeking a job. You learn to implement appropriate use cases using the highly scalable database.These days, the job market for Cassandra is on a high rise, growing at a rate of 300%. Hence, it is high time to take a step towards Apache Cassandra.

Website Creation Technology – Tips For a Beginner’s Budget

Creating a blog or  website  when you have no  website   technology  know-how  and  limited funds can be a daunting prospect at any age. More important, though, is whether you really want and need a blog or website for your business or some other aspect of your life.

Before committing time  and  money to any  website  or blog creation teacher, take some simple steps to introduce yourself to the subject of  website   technology . Focus on increasing your basic knowledge at little to no cost by gathering information from the following sources.

• Call your local library. Most libraries now include a bank of computers for their members’ use and classes intended to increase their members’ ability to use them. My local library provides the services of a computer “geek” to answer questions. Does your local geek have the know-how to teach you how to create a website or blog? Is the library planning to give a low-cost course. Or perhaps the geek has a friend in the business or has taken an online class in the subject and can recommend who you should turn to. It never hurts to ask.

• Read about creating a website. While at the library, use some old  technology  to learn some new  technology-read  a how-to book or two about creating  and  maintaining a blog. The library geek as well as the research librarian should know what titles are best suited to the beginner. Wading through five pages of a book on website creation will either kill your curiosity or plant the seed that could lead you to take the next step.

• Ask your family and friends. You know by now whether Cousin Fred or your neighbor has given up real life for the web. Do they have a blog or a website? Are they trying to sell products, promote a non-profit or create a blog for a growing family? If so, how did they learn to do it? If they took an on-or-off-line class, who with? How much did it cost? Most important, did they learn and use the information?

• Check the curriculum of local colleges and adult schools. There might or might not be a charge to take classes about web  technology , but it’s usually so little, it borders on being “free.”

• Google “how to create a blog free.” There are numerous sites offering web  technology  information online at no charge. Don’t expect too much-the information these sites offer can be incomplete and confusing. The site’s creator might presume the reader already has a certain degree of knowledge or shares only what he finds convenient to share. At the very least, you should learn some e-technology terms  and  the pro’s and con’s of blogging. Many of these sites also sell video’s, low-priced books or e-books about blogging.

• Preview calls giving online instruction: Free preview calls or webinars are offered by any serious online instructor. Savvy instructors provide varying amounts of information about creating a blog along with a pitch about their qualifications to teach the course. Most providers allow time for questions from the listeners. Even if you listen to a replay, the question and answer segment can provide valuable information both about creating a blog and the instructor’s ability to provide articulate answers. Listen to three to five of these free sessions before you decide which online instructor, if any, is the best for achieving your goal at a price you can afford.

• Read the online instructor’s blogs. Once you identify the online instructors competing for your dollars, read their blog entries-past and current-and any free online reports they offer. This can be an additional source of technical  and  practical information about  website  creation  and  will tell you even more about the teacher’s ability to communicate the online  technology  you need.

After following these steps, if you’re ready to commit yourself and your budget to a serious website creation course, then it’s time to find a knowledgeable teacher with an information-packed course of instruction that’s available for as long as you need it!

Web 3.0 Technology

In my last article, I talked a little about what web 3.0 is. In this one, I would like to talk a little about the  technology  aspect of Web 3.0  and  see if I can paint a small picture of where it is headed, but before I do that let us look at how to define it:

1. Universality to be used for every browser.

2. Mobility, each type of printer hardware.

3. Accessibility, web standards, application solution, software SaaS.

A few characteristics of Web 3.0 would be web-based solutions. (ASP, SaaA, Software, Application, the webmaster, users, DataBase server and Microformats)

Graphically characteristics: user(s) communities, sites outer linking between each other, open source and hardware layer independence, just to name a few.

Here is the list of Web 3.0 users:

Artificial Intelligence

Automated reasoning

Cognitive architecture

Composite applications

Distributed computing

Knowledge representation

Ontology (Computer Science)

Recombinant text

Scalable vector graphics

Semantic web

If you didn’t understand all the terms just mentioned, don’t worry for right now because the average person will never be involved in setting up the infrastructure of Web 3.0. However, you will be using some type of this  technology  in the future if you plan on using the web.

People think computers are getting smarter. It is just that people are programming them in such a way that it is gathering more and more information and is used in a way that we think the computer is smarter than humans.

In the context of Web 3.0, inference engines will be combining the latest innovations from the Artificial Intelligence (AI) field together with domain-specific ontologies (created as formal or informal ontologies, by, say, Wikipedia, as well as others), domain inference rules, and query structures to enable deductive reasoning on the machine level.

The term transforming the web into a database has been kicked around for several years but it looks like Web 3.0 is the word. There was another term emerged “Data Web” but we will see if this one is allowed. Only time will tell.

Let’s talk a little about RRS  technology . It will allow information to be transferred to almost any other website like Myindiatims and IGoogle. These sites will let users create their own personal home page and the RRS feed can draw its content so the user can select much of it.

As you can see,  technology  is rapidly advancing. Why not advance with it!

The Pitfalls Of Using Technology For Technology’s Sake

Being a long-time Internet entrepreneur, I have made certain observations over time. Most people who start an online business seem to go through certain “phases.” They make the same mistakes, and they react the same to different circumstances. All the while, they never realize that much of this behavior sends a glaring red signal that they are undoubtedly newbies.

There is nothing wrong with being a newbie (after all, I wasn’t born this brilliant grin). But ask any novice and they will tell you that they don’t want to appear to be a beginner. That’s why I recently felt the need to bring attention to a typical newbie mistake that you’ll want to avoid. That mistake is using every single piece of new Web  technology  you can find JUST because it is available.

I understand the appeal of new  technology . However, before loading up yet another animated graphic or phasing Web page, ask yourself a few questions.

1. Will this  technology  add value to my site? By value I mean something that will enhance (and not clutter) your Web visitor’s experience. Other than being cool, will the  technology  help in some way?

2. Will the  technology  cause an inconvenience to my visitors? Will an all Flash home page force visitors (even repeat visitors) to sit and watch a two-minute long movie each and every time they come to your site? Will tons of animated or rotating graphics files make your home page load extremely slow? Web surfers are very impatient people, you know. I can tell you from experience, they won’t wait.

3. Does the  technology  require that my site visitor do anything? Will your visitors have to download any special software or plug-ins to see your site with this new  technology ? If so, skip it! It isn’t worth the chance of visitors clicking away.

4. Is the  technology  stable? Is the chat program you’ve installed reliable? Does that new java script work the way it should? Does that streaming video feed skip and crash? If your new  technology  doesn’t perform up to speed 99% of the time, it isn’t worth causing aggravation to your visitors.

Before making any technological enhancements to your site, think about your visitors. Yes, the new  technology  may be cool, but if it doesn’t offer some true value to your customers, you would most likely be better off  and  more professional looking without it.

Create A User-Friendly Website With Web Database Development

To be successful on the internet, it is essential to have a web database development that attracts a lot of attention. Most of you are aware that it is necessary to have a successful website to generate revenue. In the past, having a well deigned website with good SEO was enough but today you need to make your site user friendly to beat your competitors and gain the attention of your visitors.

The online visitors of today are more tech savvy and many of them are equipped with sound technical knowledge. They can judge the website with its appearance and the information it presents. This makes it necessary for individuals to seek the help of a sound web database development team to develop or design a website. This is crucial as you need to take that extra leap beyond the template design, pictures and content. While opting for this, you might find that your competitors in the industry are finding it tedious and challenging to keep their website updated to cater to the changing needs of their clients.

Getting a good web database development support is essential as it offers the following advantages to you and your online customers:

  • Your database enables you to have an integrated search function and a shopping cart. This would mean a lot to your commercial website. This is essential to retain your customers for a longer period of time.

Also, the other components arranged by web database development team will be in such a way that they are displayed with just a click of the mouse. This instant accessibility draws the interest of the customers.
  • Some of the databases let the website users to register and access the products or services that you have to offer. Also, if they buy a product, then they are provided a catalogue from which they can select the products. After they select one or more from an array of products/services, an automatic invoice is generated as the proof of the transaction, which is e-mailed to the customer. This can be used by the user for further clarification of doubts or for other purposes.
  • The web database development also enables the website owners to know about the details of frequent users to the site, shopping details, details of shipment, price details, product charts, etc. Some databases also have the list of emails of the customers to whom the bills of purchase were e-mailed.
  • Certain database services are known to have a follow up service connected to the website whenever a purchase is made. They ask for the satisfaction acquired from the product purchased and require your customers to rate the services of your site with star rating method.
