System design ek process hai jismein complex software systems ya applications ke architecture ko plan kiya jaata hai, taking into account various factors like requirements, scalability, reliability, performance, security, aur usability. Ismein, system ke various components, modules, aur interactions ko define kiya jaata hai taki ek effective aur efficient solution develop kiya ja sake.
System design ke dauraan, architects aur engineers ek high-level view develop karte hain jo system ke overall structure aur functionality ko define karta hai. Ismein, following steps involved hote hain:
1. Requirement Analysis: Sabse pehle, system design process mein requirements ko clearly define kiya jaata hai. Yeh include karte hain functional requirements (kya system karna chahiye) aur non-functional requirements (jaise ki scalability, reliability, performance, security, etc.).
2. High-level Design: Iske baad, architects ek high-level design develop karte hain jismein system ke key components, modules, aur unke interactions ko define kiya jaata hai. Yeh design typically block diagrams ya flowcharts ke roop mein represent kiya jaata hai.
3. Component Design: High-level design ke baad, architects aur engineers individual system components ka design karte hain. Har component ka purpose, functionality, aur interactions ko define kiya jaata hai.
4. Database Design: Agar system mein database ka istemal hota hai, toh architects database schema ko design karte hain. Yeh schema data storage, retrieval, aur manipulation ko define karta hai.
5. Interface Design: System ke users ke liye interfaces ko design kiya jaata hai, including user interfaces (UIs) aur application programming interfaces (APIs). Interfaces ka design user interaction aur data exchange ko optimize karta hai.
6. Scalability, Reliability, aur Performance: System design mein scalability, reliability, aur performance ko bhi consider kiya jaata hai. Architects aur engineers ko ensure karna hota hai ki system ka design scalable ho taki wo grow kar sake, reliable ho taki downtime minimize ho, aur performance optimize ho taki users ko fast response mil sake.
Overall, system design ek crucial step hai software development process mein jo ek robust, scalable, aur efficient solution develop karne mein madad karta hai.
