NoSQL supports key-value stores, big table, document store and graphic databases. It offers high performance, rich query language, easy scalability and speed. NoSQL databases are unique and they are independent from Structured Query Language (SQL). SQL is generally used by relational databases as the domain-specific language. Let us discuss Apache Cassandra NoSQL database and its applications in Industry.
Apache Cassandra database offers scalability and high availability. It has proven fault-tolerance on commodity hardware and mission-critical data. Most companies have realized benefits running their applications on Apache Cassandra. The database is capable of handling all the big data, coupled with high performance, security, and easy management. Some the companies using Cassandra as their data store are listed below:
1. Adgear: Adgear use Cassandra as the data store. They collect data about the users which help them to deliver better quality and targeted ads. They manage distinct data centers consisting of Continue reading
Data mining is the process of analysing data collected from different sources into useful information. It can be used to increase business profits and keep a track on the company’s performance. Data mining software helps users to analyse data from different angles. The data is categorized, summarized and correlated with large relational databases. The main aim is to get a view of the company’s performance. With the help of data mining, business owners can get a broad view on various trends. It can show the areas where there is more profit and where there is loss. It can reveal the ways how to control the unnecessary expenditure and increase the total income. Continue reading
A NoSQL database provides an effective mechanism for storage and data retrieval. These databases excel both in terms of speed and volume. Moreover, it is increasingly been considered a viable alternative to relational databases. While working with a huge quantity of data, NoSQL is very useful. Let us discuss some of the top NoSQL databases and their performance in data management systems:
Apache Cassandra has been primarily designed to handle huge amounts of data spread out across commodity servers. It was developed by Facebook in 2008 as an open source distributed database management system. It helped Facebook to power up their inbox search feature. It offers the mixture of a column-oriented database and the columns are grouped into families. It provides a highly available service with its massive amount of consistency and replication. Apache Cassandra is preferred by companies as a back-end database. The most amazing features include BigTable modeling and the Gossip protocol. Some of the strong points favouring Apache Cassandra are highly available with no single point of failure, NoSQL column family implementation, flexible scheme, SQL like query language, support search through secondary indexes and support for replication. Apache Cassandra is a perfect solution and it provides scalability & performance needed in most applications. Continue reading
Big Data refers to the large datasets that may become difficult to work with. In some cases, the size has been known to rise to 50 TB or multiple petabytes. The technology has enabled us to handle big data in an intelligent way. We can analyse and interpret the data for its use in different industries. The only risk is that we don’t focus on the quality of data analysed. It can have many uses such as basis of product sentiment analysis, thereby leading to product improvements. It has been estimated that 90% of big data in the world has been collected within the last 2-3 years.
Modern social media platforms
Big data forms the basis of most popular social media platform i.e. Facebook. It collects more than 500 TB of data every day. This data comprises of likes, status updates, photo uploads and all related interactions. Similar is the case with blogging site Twitter which collects more than 10 TB of data per day.

The course revolves around using Google Fusion Tables, which is free online software. The concepts taught is this free course are useful in general data process of data preparation, analysis and withdrawing conclusion from analysis. The course will run from March 18th to April 4th, 2014.
Making sense of Data
After Android, Google broached another domain where it had not been before with its Chrome OS; now Microsoft is not the only company making low end, cheap notebooks which can be used for video chatting and light internet surfing etc. Previously, Chromebook was targeted as a solution for low end users who intended to use apps available on-line. The screen was low resolution and the processor had limited power. The laptop started instantly and was quite user friendly. However, nobody counted it as a ‘real’ laptop. It was merely half a step above a tablet. But now Google is soon to release Chromebook 2 with its partner Samsung and everyone thinks it will be almost a real laptop.
With the release of Android mobile OS, Google opened a floodgate of new mobile technology. With the release of newer and better devices every day from various companies it has been ensured that mobile technology becomes as pervasive as possible. I don’t know about anyone else but my phone is surely the center of my world. The market of smart phones has become so competitive that a company can’t survive just by creating ‘good’ products. The products must have something extra that makes people want it.
Samsung’s latest release has taken the cake for me in that regard. With the release of Samsung Galaxy S5 along with Gear 2 and Gear Fit, the company has created a buzz in the smart phone market. And why should it not when the features are awesome! As I write this article, I have no idea which feature I should deem to be the best. From looks to functionality the phone is a top notch premium piece of technology.
Here’s a look at the features:
With a unique perforated back cover and four different vivid colors, the phone looks amazing and has a comfortable grip too. It has a 5.1 inch full HD super amoled screen with adaptive display which makes video viewing an experience of a lifetime. For photography enthusiasts, the phone offers at 16 megapixel rear camera with autofocus feature. Samsung claims the speed of autofocus to be 0.3 seconds. It has both contrast autofocus and phase detection autofocus which is a world first in smart phones. Another feature is the selective focus which blurs the background and lets you focus on one specific object. Continue reading
