What is SQL?

SQL or the Structured Query Language is the most common and popular programming language for the relational database management system. It is a language designed to extract, store, insert, delete, update and manage data for structured data and strategic analysis.

SQL is widely used by top tech companies like Facebook, Whatsapp, etc for data processing solutions. It is used for different types of RDBMS including Oracle, MySQL, SQLServer, etc.

Functions of SQL:

• Perform queries on the database
• Database Retrieval
• Set permissions on tables, views
• Can insert records into the database
• Update records in a database
• Delete records from a database
• Create new databases, or new tables in a database
• Create stored procedures & views in a database

What is NoSQL?

NoSQL database provides a mechanism for storage and retrieval of data that is modelled other than tabular form. It was introduced by Carl Stroz in the year 1998 called a Non-relational database. Now, it stands for Not only SQL. It is not limited to storing data in tables, instead, enables the big data to be stored in the structured, unstructured, semi-structured or polymorphic form.

It is not limited to storing data in tables, instead, enables the big data to be stored in the structured, unstructured, semi-structured or polymorphic form.

Companies like Twitter and Google, with a tremendous amount of data set like the user data of the social platforms, prefer to use NoSQL over any other RDBMS.

Key Features

Features of SQL

• Provide High-Performance Capabilities
• SQL is a powerful tool as it is highly compatible with all types of RDBMS like MySQL, SQL Server, Oracle Database, MS Access, etc.
• Data Consistency: SQL adheres to ACID properties with a strict schema that ensures better data consistency.
• Ensures Vertical Scalability
• Handle Large Transactions with efficiency
• Robust Security Measures like rigid schema, data consistency, data integrity, regular updates, etc.
• Suitable for every type of organization – large or small.
• SQL is easy to learn and manage
• Open Source Programming Language
• Supports Data Definition Language and Data Manipulation Language to query the databases

Features of NoSQL

• NoSQL has higher scalability than other database management systems
• Schema Free: You do not need to define the schema of the database before storing the data onto the system.
• NoSQL allows the distribution of data on more than just one device.
• With NoSQL Database, you do not require specialized or complex hardware or storage solutions.
• Does not require data normalization
• Simple API for easy user interfaces
• Can store unstructured, semi-structured, or structured data.
