Study Notes

NoSQL Databases

Designed for managing non-tabular data
Schema-less or flexible schema
Handles various data types: structured, semi-structured (JSON), and unstructured (text, images, logs)
Horizontally scalable

When NoSQL is Used

Necessary when scalability is needed for large data volumes
Flexibility is required for quick iterations and changes
Important for performance in big data and real-time applications
Optimized for specific data models and access patterns

Types of NoSQL Databases: Document Stores

Used for content management systems
Store documents within a collection that can have different fields or structures
No strict schema; developers store varied data formats within a single collection
Useful for storing products with differing attributes depending on the category
Example use case: a news website storing articles with title, body, author, tags, and publication dates, accommodating multimedia content, and distributing load across multiple servers

Key-Value Stores

Used for caching, session management, and real-time bidding
Example use case: managing user sessions in an online shopping platform
Uses unique session IDs as keys and session data (cart contents, authentication) as values
Fast access and updates to session information

Graph Databases

Graph data model: represents data as nodes (entities) connected by edges (relationships)
Useful for scenarios where relationships between data points are important
Example Use Case: social media platforms to manage and analyze relationships and recommend friends, detect communities, and identify influencers
Modeling complex relationships such as friendships, messages, and likes efficiently

Neo4j Products

Neo4j Database: Core product, available in Community and Enterprise editions
Neo4j Aura: Fully managed cloud service for deploying and running Neo4j databases, including scalability, security, and reliability
Neo4j Desktop: Desktop application for development and management of local Neo4j databases
Neo4j Bloom: Visualization and exploration tool for graph data
Neo4j Graph Data Science Library: Collection of algorithms and tools for analyzing graph data, like centrality analysis, community detection, and similarity analysis
Neo4j AuraDB for Google Cloud: Fully managed graph database service on GCP
