SQL vs NoSQL– Which one is Your Pick!

SQL database stands for ‘Structured Query Language ‘ which is the standard language for relational database managements systems whereas NoSQL is a database that offers techniques for storing and recovering of data sculpted in means other than the tabular relations used in relational databases. Here are few points to explain the invariable difference between them.

SQL-Vs-NoSQL

Key Features of SQL: SQL also well known as Relational database managements systems has some key characteristics and they are follows

– Persuade normalization to decrease data redundancy

– Table JOINs to recover associated data from multiple tables in a single command

– Demands a schema that describes a certain table prior to its usage.

– Implement data reliability policies.

– Offer transactions with an assurance for updates.

– Applies powerful declarative language for querying.

– Provides adept support, expertise and tools.

 

Key Features of NOSQL: NoSQL are known as Non relational database managements systems and the key features are as follows

– Must be denormalized in order to obtain information in a single document.

– Require JOINs presuming denormalized credentials used.

– Assured updates in single document.

– Provide outstanding performance.

– Utilize JSON data objects for querying.

– An innovative, exciting technology.

 

Let us understand few other features of these two database managements systems:

 

– SQL databases have preordained representation whereas NoSQL databases have dynamic plans for unstructured data.

– Elaborate queries: SQL database is adept for complex queries whereas NoSQL are not a good fit for difficult inquiries. The queries in SQL are very powerful as compared to NoSQL language.

– Storage of Data: SQL is stored in relational form in rows and columns which contains specific entry and columns having separate data points. And NoSQL include a host of databases with graph, columnar and key value respectively.

– Scalability: SQL databases are upright expendables. You can manage the rising load by extending the CPU, RAM, SSD, etc, on a single server. And NoSQL databases are horizontally scalable that allows you to add few more servers easily to efficiently handle large traffic.

– Support: Outstanding support is available for SQL database with consultants for heavy scale distribution and NoSQL is available with few outside experts and community for its support.

– Properties: SQL databases highlights ACID properties ( Atomicity, Consistency, Isolation and Durability) whereas the NoSQL database pursues the Brewers CAP theorem ( Consistency, Availability and Partition tolerance )

 

Therefore SQL and NoSQL are contrary to each other having fierce competition and are being preferred by many companies in tandem. So it is best advised to open up to myriad technologies that will give a better vision to differentiate between SQL and NoSQL.
