Data Storage
Data storage refers to the technologies, systems, and methods used to retain digital information for later use. It encompasses a wide range of solutions from physical hardware like hard drives and SSDs to logical structures such as databases and cloud storage services. The primary goal is to ensure data persistence, accessibility, and integrity over time.
Developers should understand data storage to design efficient, scalable, and reliable applications that handle user data, logs, or system states. It is crucial for scenarios like building databases, implementing caching mechanisms, or deploying cloud-based services where data durability and retrieval speed are key. Mastery helps in selecting appropriate storage solutions based on factors like volume, velocity, and variety of data.
