1.) A graph database called Neo4j was created in the 1990s by three guys who had a problem related to language translation. They realized that graphs could model the relationships between concepts. Neo4j became popular for modeling social networks, recommendation systems, and other applications that involve interconnected data.
2.) Neo4j started as an idea, progressed to a prototype, and is now used in production by many companies to model complex relationships in domains like social media and knowledge graphs. It allows modeling data as nodes connected by relationships, and uses the Cypher query language.
3.) Some popular applications built using Neo4j include the digital paper app 53 and customer mapping tools that model how

Document-Oriented Database
A document-oriented database is a computer program designed for storing,
retrieving, and managing document-oriented information, also known as semistructured data. Document-oriented databases are one of the main categories
of so-called NoSQL databases and the popularity of the term "documentoriented database" (or "document store") has grown[citation needed] with the
use of the term NoSQLitself. In contrast to well-known relational databases
and their notions of "Relations" (or "Tables"), these systems are designed
around an abstract notion of a "Document".

Column Oriented Database
A column-oriented DBMS is a database management system (DBMS) that
stores data tables as sections of columns of data rather than as rows of data. In
comparison, most relational DBMSs store data in rows. This[ambiguous] has
advantages for data warehouses, customer relationship management (CRM)
systems, and library card catalogs, and other ad hoc inquiry systems[1] where
aggregates are computed over large numbers of similar data items.

Key Value Stores
They all allow storage of arbitrary data which is being indexed using a single key to allow retrieval.
Key value stores allow the application developer to store schema-less data. This
data is usually consisting of a string which represents the key and the actual
data which is considered to be the value in the "key - value" relationship.
They all allow storage of arbitrary data which is being indexed using a single key
