Study Notes
NoSQL Databases
- NoSQL databases are designed to manage non-tabular data.
- They are schema-less or flexible.
- They can handle various data types: structured, semi-structured (JSON), and unstructured (text, images, logs).
- Horizontally scalable.
When to Use NoSQL
- When scalability is needed (to handle large volumes of data easily).
- When flexibility is needed (to quickly adapt to changes).
- When performance is important (optimized for specific data models and access patterns).
- For big data and real-time applications.
Types of NoSQL Databases: Document Stores
- Document stores are used for content management systems (like websites).
- Documents in the same collection can have different fields or structures.
- No strict schema enforcement.
- Flexible for storing various data formats in a single collection.
- Useful for storing products with varying attributes based on the category.
- Example use case: a news website to store articles (with title, body, author, tags, and publication date).
Key-Value Stores
- Used for caching, session management, and real-time bidding.
- Example: An online shopping platform uses Redis to manage user sessions.
- Each user's session is stored with a unique session ID (key) and session data (e.g., cart, authentication).
Graph Databases
- Graph databases represent data as nodes (entities) connected by edges (relationships).
- Useful for scenarios where relationships between data points are important.
- Examples: Social networks, recommendation systems, network and IT operations, and fraud detection.
- Enables efficient modeling of complex relationships.
- Example use case: A social media platform using Neo4j to manage its social graph.
Neo4j Products
- Neo4j Database: Core product, available in Community and Enterprise editions.
- Neo4j Aura: Fully managed cloud service for Neo4j databases.
- Neo4j Desktop: Desktop application for development and management of local Neo4j databases.
- Neo4j Bloom: Graph visualization and exploration tool.
- Neo4j Graph Data Science Library: Algorithms for analyzing and extracting insights from graph data.
- Neo4j AuraDB for Google Cloud: Fully managed graph database service hosted on Google Cloud.
