Flexible data model − Neo4j provides a flexible, simple and powerful data model, which can be easily changed according to the requirements.

It uses Cypher Query Language (CQL) for creating, modifying, interconnecting and deleting data (nodes). It is a NoSQL based ACID complaint transactional database.

Neo4j is a schema free graph database management system. This enables the user to navigate deep hierarchies, find hidden connections between distant nodes, and discover inter-relationships between nodes. Whereas in graph databases, relationships are stored as data elements (the nodes) in a much more flexible format. In relational databases, we can store relationships as tables and navigate them using JOIN operations or cross-lookups which is time consuming, not cost-effective method.

Properties - key/value pairs stored within nodes or relationships.

Labels - attributes that group similar nodes together.

Relationships - the connections between the entities, similar to foreign keys in a relational database.

The fundamental components of a graph database are: Graph database uses graph structures with nodes, relationships and properties to store and visualize data. The connections between the data becomes equally important as the data itself. This becomes complicated when it involves a lot of indirect relationships between the data.

Relational database stores data in the form rows and columns and relations are mentioned using foreign key constraint. In this session, we will learn Neo4j basics and try basic clauses such as CREATE, MATCH, WHERE, RETURN, SET, DELETE etc. It provides a declarative query language known as Cypher (CQL) for querying data. A major feature of Neo4j is creating interconnection between various entities (nodes). It stores and displays data in the form of graph and represents data using nodes and edges and relationships. Neo4j is a highly scalable, schema free graph database management system. It allows you to easily store data and analyze the relationships among them. A graph database stores information as relationships between entities and represents this data using nodes and edges.
