Databases are the unsung heroes of modern technology, powering everything from your favorite social media platform to enterprise-grade systems. But have you ever wondered what makes databases so fast and efficient? 🤔 The secret lies in the data structures they use! Here’s an engaging dive into the 11 key data structures that power databases and make them the performance engines we rely on daily.

1️⃣ Hash Indexes

Hash indexes use hash functions to map keys to specific locations in memory, enabling lightning-fast lookups. ⚡

• Use Case: Frequently used for exact-match queries like finding a user by their ID.
• Advantages: O(1) time complexity for reads and writes in ideal scenarios.
  🚨 Fun Fact: They’re the secret sauce behind fast key-value stores like Redis!

2️⃣ Skip Lists

Imagine a linked list on steroids, with “skips” that let you jump ahead. Skip lists are optimized for fast search and insert operations. ⏩

• Use Case: Perfect for in-memory indexes in systems like Redis.
• Advantages: Simpler and more memory-efficient than B-Trees…
