Should Each Microservice Have Its Own Database or Table?

Description

This video clearly explains the golden rule in microservices: database per service. We discuss how each microservice should control its own data, a core principle for robust distributed systems. Understanding this is key for effective data management in modern software engineering. 🌐 **Should Each Microservice Have Its Own Database or Table?** Confused about **microservices architecture** and how to design your database? Should each microservice have its **own database**, or can they share **tables in one database**? This is one of the **most important design decisions** in modern system design — and getting it wrong can lead to **scaling issues, data problems, and tight coupling**. In this video, you will understand the **right approach step by step**, in a very simple way. ✅ **Inside this video:** * What are **Microservices** and how they work * What is **Database per Service pattern** (very important concept) * Difference between **shared database vs separate database** * Why sharing tables can create serious problems * Benefits of giving each microservice its own database * Real-world examples of microservice data design * Common mistakes developers make * Best practices for scalable architecture 💡 **Important concepts explained:** * **Microservices Architecture** – breaking applications into small independent services * **Loose Coupling** – services should not depend heavily on each other * **Data Ownership** – each service controls its own data * **Scalability** – ability to handle growth smoothly * **API Communication** – services talk through APIs, not shared tables 🎯 **Perfect for:** * Beginners learning **system design** * Developers working with **Spring Boot, Java, or backend systems** * Anyone confused about **database design in microservices** * Engineers preparing for **interviews or architecture discussions** ⚠️ Many developers share databases between microservices to make things easy — but this can create **serious long-term problems**. This video explains the **correct approach used in real-world scalable systems**. 👉 **If you want simple and practical system design tutorials like this, subscribe now and level up your backend skills step by step.** #Microservices, #SystemDesign, #DatabaseDesign, #SoftwareArchitecture, #BackendDevelopment, #Java, #SpringBoot, #MicroservicesArchitecture, #TechExplained, #Coding
