NoSQL And RDBMS Advantages And Challenges

Typically, the programmers have to implement one or two types of databases, relational and non-relational. According to the query language, they’re also known as SQL and NoSQL, respectively.Today, we’ll be talking about the relational (RDBMS) databases and the non-relational (NoSQL) databases by comparing their pros and cons.


  • What is an RDBMS?
  • RDBMS stands for Relational Database Management System, and they’ve been around for more than 40 years. With a need to integrate data depending upon relational dependencies, the use of traditional paper registers has almost vanished, especially in globalized businesses.RDBMS allows populating large structures of data in which one or more entities are dependent upon one another, hence the word “Relational.” Lastly, they’re vertically scalable.

  • What is NoSQL?
  • NoSQL primarily refers to the databases that do not necessarily depend upon the consistent and accurate definition of data. This means NoSQL is used to populate large vast sets of data that have incredibly complex and constantly changing data structures.As opposed to RDBMS, this type of database is horizontally scalable.

  • Advantages of NoSQL over Relational Databases (RDBMS):
  • Following are some significant benefits of using NoSQL:

  • Since the data in the NoSQL database is horizontally scalable, It is effortless to manage. You can add more to your pool of resources only by adding more machines.
  • Maintaining NoSQL is less expensive as compared to managing an RDBMS, which requires workforce and massive servers.
  • Data implementation on NoSQL is easier, since NoSQL is open-source and require inexpensive-servers.
  • Moreover, NoSQL is schema-less, which means you can populate the database without any predefined schema.
  • As opposed to RDBMS, NoSQL supports integrated caching, which increases data output performance.
  • NoSQL has a fixed data model as opposed to the RDBMS.

  • Challenges of NoSQL over Relational Databases (RDBMS):
  • You went through the pros of using NoSQL above, but NoSQL does have the following limitations:

  • As the NoSQL database is open-source, it can also turn out to be its greatest weakness because there aren’t many defined standards for NoSQL. Consequently, no two NoSQL databases can be equal.
  • NoSQL is the latest technology, so the developers are still in the learning mood. It’s challenging to find experts for NoSQL.
  • There are no stored procedures in the NoSQL Database (mongodb).
  • The user-friendly tools to access the database aren’t easily as accessible in the market as of RDBMS’s.
  • Since it is not relational, the NoSQL database cannot explicitly deal with complex integrated structures if needed.

  • In conclusion, it’s hard to make an informed decision about which database is better. The developer has to make a proactive decision about choosing the database, according to requirements.
