Study Notes
RDBMS and NoSQL
- RDBMS provides a structured data storage mechanism with strict schema enforcement.
NoSQL Complementing RDBMS
- NoSQL complements RDBMS by providing a flexible and scalable data storage solution for handling large amounts of unstructured or semi-structured data.
Key Features of NoSQL
- NoSQL databases provide a flexible schema, which allows for easy adaptation to changing data structures.
- NoSQL databases offer high scalability and performance, making them suitable for big data and real-time web applications.
- NoSQL databases are designed to handle large amounts of unstructured or semi-structured data.
CAP Theorem
- According to the CAP theorem, 'Consistency' refers to every read operation will see the most recent write or an error.
Companies Using NoSQL
- Amazon uses NoSQL for its large-scale e-commerce platform.
Partition Tolerance
- Partition-tolerance in a system refers to the ability to continue functioning even when network partitions or network failures occur.
Consistency and ACID
- Strong consistency is associated with the ACID (Atomicity, Consistency, Isolation, Durability) properties in large systems.
Companies Building Big Applications
- Both Amazon and Yahoo build big applications on CAP and BASE (Basically Available, Soft-state, Eventual Consistency).
Key-Value Stores
- The primary focus of Key-Value stores is to provide fast and efficient data retrieval using a unique key.
Database Based on Google’s BigTable
- HBase is a type of database based on Google’s BigTable paper.
