NoSQL databases, also known as not only SQL, are non-tabular databases, and store
data differently from relational tables.
What is NoSQL database?
NoSQL databases come in a variety of types based on their data model. The main ones
are key-value, wide-column, document and graph
What are types of NoSQL databases?
Traditional RDBMS uses SOL syntax to store and retrieve data for further insight.
Instead, in NoSQL databases, it encompasses a wide range of database technologies
that can store structured, semi-structured, and unstructured data.
Differences in RDBMS and NoSQL data storage and retrieving .
SQL databases are relational whereas NOSQL databases are non-relational
SQL databases use structured query language and have pre-defined schema whereas
NOSQL databases have dynamic schemas for unstructured data.
SQL databases are vertically scalable while NoSQL databases are horizontally scalable.
SQL databases are table-based while NOSQL databases are key-value, document,
wide-column, graph etc.
Sol databases are better for multi-row transactions while NOSQL is better for
unstructured data like documents or JSON
, SQL follows ACID properties while nosql follows CAP.
Examples of SQL databases are MySQL, eSQL, Oracle, MS-SQL Server etc while NOSQL
is MongoDB, HBase, Cassandra, Neo4j etc.
NoSQL databases are mainly categorized into four types - key-value pair,
Column-oriented (wide-column), Graph-based and document-oriented
What are the types of no SQL databases?
Data is stored in key /value pairs.
How is data stored in key - value pair database
Key - value pair database is designed in such a way to handle lots of data and heavy load
In what way is key - value pair database designed?
Key-value where storage data faces store data as hash tables where each key is unique,
and the value can be JASON, BLOB (Binary Large objects) string et cetera
Explain key - value pairs storage
Keyvalue pairs is a kind of database used as a collection, dictionaries, associative
arrays et cetera. Key value stores help the develop or to store schema - less data. They
work best for shopping cart contents.
