Study Notes

Introduction to NoSQL Databases

  • NoSQL databases are designed for managing non-tabular data.
  • They offer schema-less or flexible schemas.
  • They are horizontally scalable.
  • They handle various data types (e.g., structured, semi-structured, unstructured).

When to Use NoSQL Databases

  • When scalability is needed.
  • When flexibility is needed (dynamic schema design, quick iterations).
  • When performance is important.
  • For big data and real-time analytics applications.

Types of NoSQL Databases: Document Stores

  • Document stores are used for content management.
  • Documents within a collection can have different fields or structures.
  • No strict schema enforcement.
  • Useful for storing products with varying attributes.
  • Example use case: a news website storing articles with different fields.
  • Flexible schema allows easy addition of new fields without altering existing documents.
  • Can handle millions of readers by distributing load across multiple servers.

Key-Value Stores

  • Used for caching mechanisms, session management, and real-time bidding.
  • Example: online shopping platforms using Redis to manage user sessions.
  • Store data as key-value pairs.

Graph Databases

  • Represent data as nodes connected by relationships (edges).
  • Suitable for scenarios with important relationships between data points.
  • Suitable for social networks, recommendation systems, and fraud detection.
  • Example use case: a social media platform using Neo4j to manage and analyze its social graph.

Neo4j Products

  • Neo4j Database: core product, available in Community and Enterprise editions.
  • Neo4j Aura: fully managed cloud service for deployment and running Neo4j databases (scalability, security, reliability).
  • Neo4j Desktop: desktop application for development and management of local Neo4j databases.
  • Neo4j Bloom: graph visualization and exploration tool for graph databases.
  • Neo4j Graph Data Science Library: algorithms and tools for analyzing and extracting insights from graph data.
  • Neo4j AuraDB for Google Cloud: fully managed graph database service on GCP.
