nosql vs sql
NoSQL vs SQL

The tough choice of NoSQL vs SQL. An important decision for any business that may pay the price for down the road if you don’t plan accordingly. Here, we break down the important distinctions and discuss NoSQL vs SQL for you to make an informed decision.

What is NoSQL

NoSQL or Not Only SQL is an alternative to relational databases such as MySQL, Postgres, and SQL Server. Typically NoSQL databases are popular for working with large sets of data as data is stored in the form of flat collections so reading or writing operations is much faster. There is also less management for NoSQL databases as they support automatic repair, data distribution, and simpler data models.

MongoDB, Couchbase, and Cassandra are popular NoSQL databases, but what do their queries look like? If NoSQL is all about leaving SQL behind, then what happens? These are fair questions, for example MongoDB uses its own syntax that kind of resembles JavaScript. Let’s take a look:

db.inventory.find( { status: "D" } )

In the above query the example selects from the inventory collection all documents where the status equals “D”. It is not too difficult to follow, but does feel a little foreign if you are used to SQL.

What is SQL

SQL or Structured Query Language is a language used in programming and designed for managing data held in a relational database management system. Some examples of popular SQL databases are Postgres, Microsoft SQL Server and MySQL. One of many reasons for its popularity is how portable it is. SQL can be used in the program in PCs, servers, laptops, and even some of the mobile phones. Unlike NoSQL databases, SQL databases have an established, well defined standard. The language is also very straightforward, let’s take a look at it:

SELECT * FROM inventory WHERE status = "D"

In the above query the example selects from the inventory collection all documents where the status equals “D”. Sound familiar? That is because it is doing the same thing the MongoDB query is doing.
