An Overview of NoSQL Databases

We have seen in recent time, there is a significant rise in new types of databases. A new database that is growing fast in the current time is the NoSQL database. This new database is challenging the existing relational database model. Relational database has their roots in the software industry for over a long time, they provide an effective tool to store the data, it also enables other features of data like controlling data, data transaction, maintaining persistence and concurrency by using standard interfaces and tools to integrate application, reporting.

What do you mean by NoSQL


NoSQL does not actually mean the only SQL, it implies that when developing and designing the software or a product more than one storage option can be used by the application developer depending upon the application requirement. To discuss new database NoSQl a hashtag was chosen as #nosql to meet-up. The reason for the growth of NoSQL is due to its Polyglot persistence. There is no accurate definition for NoSQL but one can make an observation, depending upon following terms

  1. No relational model used
  2. Works well with clusters
  3. It’s an open-source platform
  4. Mostly developed for the 21st century
  5. Uses less Schemas

NoSQL Database

Software developers are dissatisfied with the conflicts that take place between relational data structure and in-memory data structure while developing an application. Software development is now using NoSQL database which allows them to develop applications without converting from in-memory structure to relational structures.

The significant growth of the web-based platform has created a change in the data storage models. Running clusters will help developers to support large amounts of data.

Relational database was not developed to run on clusters. The ERP applications need larger amounts of data to be stored, the needs of ERP systems are much more different than the data storage needs of Facebook or Etsy, just for example.


NoSQL database is currently in rise due to the choices it offers to application developers; this does not indicate the end of Relational Database Management system RDBMS database. This tells us that we are entering into a new digital era of polyglot persistence. Polyglot Persistence is a technique that allows application developers to use different storage techniques that will help them to manage data storage needs of different sizes. The Polyglot persistence can be adapted by an organization or can be applied within a single application.
