Study Notes
NoSQL Databases
- NoSQL databases are designed for managing non-tabular data.
- They offer schema-less or flexible schemas.
- They are horizontally scalable.
- They can handle various data types (structured, semi-structured, unstructured).
When to Use NoSQL Databases
- When scalability is needed (handling large data volumes).
- When flexibility is required (dynamic schema changes).
- When performance matters.
- In big data and real-time analytics applications.
Types of NoSQL Databases: Document Stores
- Document stores are used for content management systems.
- Documents within a collection can have different fields or structures.
- Schema flexibility allows different data formats.
- They are useful for storing products with varying attributes.
- Example use case: A news website using MongoDB to store articles (title, body, author, tags, etc.).
- MongoDB's flexible schema allows for easy addition of new data fields.
- This scalable approach allows for handling millions of users.
- Example data structure: {"carID": 101, "brand": "Toyota"}.
Key-Value Stores
- Key-value stores are used for caching, session management, and real-time bidding.
- Redis and DynamoDB are examples.
- Example use case: An online shopping platform using Redis to manage user sessions.
Graph Databases
- Graph databases represent data as nodes connected by relationships (edges).
- They are suitable for scenarios with important relationships between data points.
- Use cases include social networks, recommendation systems, and fraud detection.
- Example use case: A social media platform using Neo4j to manage relationships and analyze social graphs (friendships, messages, likes).
Neo4j Products
- Neo4j Database: The core product, available in Community and Enterprise editions.
- Neo4j Aura: A fully managed cloud service for Neo4j deployments, offering scalability and reliability.
- Neo4j Desktop: A desktop application for developing and managing local Neo4j databases.
- Neo4j Bloom: A graph visualization and exploration tool.
- Neo4j Graph Data Science Library: Algorithms and tools for advanced graph analytics.
- Neo4j AuraDB for Google Cloud: A fully managed graph database service on GCP.
