Database - [work]

: The logic that connects tables (e.g., linking a customer's ID to their specific orders). The 7 Phases of Design

A unique ID for every row (e.g., Social Security Number, ID). No two rows can have the same Primary Key.

: A single row containing all fields for one entity (e.g., one specific customer’s details). database

: Ensures that committed data survives unexpected system failures, crashes, or power outages. The CAP Theorem and BASE Properties

Prevents application crashes and maintenance windows during big product updates. : The logic that connects tables (e

To understand a database, you must first understand its smallest parts:

A in a computer system, designed for rapid search, retrieval, modification, and management . Managed by a Database Management System (DBMS) , databases form the foundational infrastructure for virtually all modern applications, from global financial networks to local e-commerce storefronts. 1. Evolution of Data Storage : A single row containing all fields for one entity (e

In the context of databases and AI, a is a high-level, abstract representation of data extracted from the intermediate layers of a deep neural network . Unlike traditional "handcrafted" database features (like a customer's age or a product's price), deep features are automatically learned by models to capture complex patterns that are difficult for humans to define. Deep Feature Synthesis (DFS)

Non-relational databases skip the rigid table structure. Instead, they use flexible data models designed specifically for unique data requirements.

Modern data needs require different architectural approaches: Relational Database Design – Full Course

Non-tabular and can be document-oriented, graph-based, or key-value pairs.
