A NoSQL is a non-relational (alternative model for relational database), distributed, open-source, scalable next generation database. The community often interprets it as ‘Not Only SQL’. It is the viable alternative for relational database management system (RDBMS) and widely deployed for interactive web and mobile applications.
The Internet companies (including Google to overcome the limitations of relational data bases) and the enterprises (with big users and big data) specifically implements the NoSQL technology because of the following advantages.
1] Today, billions of individuals are dependent on the Internet or the mobile applications. Furthermore, the measure of time they spend online is relentlessly developing, making a blast in the number of concurrent users. And these numbers are never static. At a given time, the number may outburst or simply shrink. The large number of users, dynamic pattern of usage (abrupt increase or decrease in a given time) and performance maintenance for the users, calls for an easy and scalable database technology. Rightly, NoSQL database management system is much easier and scalable meeting the demands as compared to RDBMS.
2] Research firm IDC estimates that by 2020, the size of the world’s digital data may shoot up to 44 zettabyte. The ever expanding array of data includes geo-location data, social graphs, machine logging data, and, etc. Further, the data value is under the influence of shopping, advertising, entertainment and so on. Obviously, capturing and using the data is not a joke. Rightly, NoSQL accommodates the added data with more flexibility without disrupting the content structure changes and of course with less code, easy maintenance and no debugging issues.
Though it accommodates big data (big by volume, variety and velocity), organizations must opt for database optimization to avoid server performance problem through database and server monitoring tools.
3] Going further, billions of devices are connected to the Internet that includes tablets, systems installed in hospitals, cars, warehouses and, etc. These devices receive data through billions of sensors on environment, location, movement, temperature and more. Moreover, enterprises influence the Internet. The ability to access global, operational data in real-time requires a fixed schema and structured data. Rightly, NoSQL technology is the solution.
4] To add on to the list, applications utilize three-tier architecture that is they are accessed through a web browser or the mobile app connected to the Internet. A load balancer in the cloud directs the incoming traffic to a scale-out tier or web or application server. As the number increases, a commodity server is added to the web application tier to distribute and absorb the load. Rightly, NoSQL technology fits this architecture by providing an easy, linear and dynamic approach to data base scaling.
5] The document-oriented NoSQL database receives the data and aggregates it into documents using the JSON format. Further, the format of the inserted data can be changed any time without application disruption.
Thus, NoSQL technology have brought highly scalable, non-relational databases handling vast amounts of information. It offers data management capabilities for the Internet companies and the enterprises alike.
which favors the Internet companies and business applications.
