Layered technology, ya talti praudyogiki, ek software engineering concept hai, jisme software architecture aur development ko alag-alag layers mein organize kiya jata hai. Har layer apne specific functionality aur responsibilities ke saath hota hai aur unko hierarchically arrange kiya jata hai. Har layer ke andar related components, modules, aur services shamil hote hain.
Layered technology ka upyog karte hue, ek complex software system ko modular aur manageable tarike se develop kiya ja sakta hai. Isse code reusability, maintenance, aur scalability mein bhi suvidha milti hai. Har layer apne abstraction level, interface, aur interaction rules ke saath define hota hai.
Ek layered architecture generally niche diye gaye pramukh layers se bana hota hai:
- Presentation Layer: Yeh layer end users aur external systems ke saath interaction handle karta hai. Ismein user interface (UI) components, application navigation, aur presentation logic shamil hote hain. Is layer ka focus user interaction aur presentation aesthetics par hota hai.
- Application Layer: Application layer mein software ke core functionality, business logic, aur processing logic shamil hote hain. Yahaan par use cases, business rules, aur algorithms implement kiye jate hain. Is layer ka focus data processing aur application-specific operations par hota hai.
- Data Layer: Data layer mein data storage, retrieval, aur persistence ke liye responsible components hote hain. Yahaan par databases, data models, data access modules, aur data manipulation logic shamil hote hain. Is layer ka focus data management aur data integrity par hota hai.
Har layer apne immediate higher aur lower layers ke saath communication aur interaction karta hai. Communication usually ek defined interface (API) ke through hoti hai, jisse layers ke beech data aur requests exchange kiye jaate hain.
Layered technology ke fayde hai ki software development aur maintenance simplified ho jaati hai, components ko reusable banaya ja sakta hai, aur har layer ko alag-alag teams ke saath parallel development kiya ja sakta hai. Iske saath hi, isse code readability, flexibility, aur extensibility mein bhi suvidha milti hai.
Yeh the layered technology ke bare mein jankari. Iske alawa, dusre software architecture concepts jaise ki microservices architecture, client-server architecture, aur event-driven architecture bhi prasiddh hai, jo bhi specific use cases aur requirements ke anuroop istemal kiye ja sakte hain.
