Hello and welcome to PodinaTutorials.com blog. Here in this article I’m going to talk about the difference between SQL and NoSQL. We’ll briefly discus when to use SQL and when to use NoSQL. But before proceeding to the actual topic, keep in mind that both SQL and NoSQL are completely different concept. Have a look to both of them in detail below:

SQL:

SQL stand for Structured Query Language. SQL is a database language to perform CRUD functions. In SQL databases the data are stored in the form of tables. CRUD mean Create, Retrieve, Update and Delete

CRUD mean Create, Retrieve, Update and Delete

SQL works on the concept of RDBMS. In SQL we use queries or commands to perform the CRUD functions on database tables.

RDBMS stands for Relational Database Management System

The queries use in SQL are standardized and can migrate very easily from one system to another system, and this process is also called Portability.

Example:

Queries are used to SELECT, RETRIEVE, UPDATE or DELETE record from specific table in database.

IMPORTANT:

SQL (Structured Query Language) used to build large and complex databases

Some SQL databases are:

1. MsSQL
2. MYSQL
3. Oracle
4. PostfreSQL
5. Sqlite etc.

NoSQL

In NoSQL all the features are reversed. NoSQL is completely opposite from SQL as the name suggest.
NoSQL is a Non-Relational Database Management System, which can be used to develop a database for small company or organization. NoSQL databases have greater flexibility and stored data in the form of Graphs, Charts and Objects etc.

IMPORTANT:

NoSQL can be used for Small organizations who’s Requirements is less

PROBLEMS:

1. Misguiding features when Migrating to another system
2. Lack of standardization

Some NoSQL databases are:

1. BigTable
2. RavenDB
3. MongoDB
4. Cassandra
5. Redis etc

Difference in Table format.
