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.
