Creation Phase ya "Srishti Avastha" software development life cycle ka pehla charan hota hai, jahan par ham naye software ke liye design aur planing karte hai. Is avastha mein hum requirements ko gather karte hai aur unke according software ki architecture taiyaar karte hai.
Is phase mein ek project manager, business analyst, software architect aur team ke members involved hote hai. In sabhi logon ko apne roles aur responsibilities ki puri jaankari honi chahiye.
Ek udaharan se samajhte hai- Maan lo humne ek E-commerce website banane ka decision liya hai to Creation phase mein hum yeh decide karenge ki konse features hone chahiye jaise ki product listing, add-to-cart, checkout, payment gateway integration etc. Iske saath hi hum decide karenge ki kaunsa programming language aur framework use karna hai aur kaise database structure taiyar karna hai.
Creation phase mein software ka initial blueprint taiyar hota hai jiske baad ise further develop kiya jata hai.
Code phase kya hai?
Code phase ek term hai jo GPS (Global Positioning System) mein use hoti hai. Jab GPS receiver location determine karne ke liye satellite signals ka use karta hai, toh wo ek timing code ka upyog karta hai jo satellite dwara transmit kiya gaya hai. Ye timing code, GPS signal ke saath ek saath chalta hai aur jab GPS receiver us signal ko capture karta hai, tab wo signal ke starting point se kitni doori par hai, uska pata lagata hai.
Is process mein, GPS receiver ek internal clock ka upyog karta hai jo satellite dwara transmit kiya gaya timing code ke saath syncronize hota hai. Agar in dono clocks ke beech mein koi bhi difference hai, toh receiver us time delay ko calculate karke apni position determine karta hai.
Example ke liye, imagine karo ki tum ek GPS receiver lekar jungle mein ho aur apni exact location pata karna chahte ho. Jab tum GPS receiver ko on karte ho, toh wo satellite signals ko receive karna shuru karta hai. Har signal ke saath ek timing code bhi hota hai jo GPS receiver ke andar ki clock ke saath syncronize hota hai. Is tarah se, receiver calculate kar sakta hai ki us signal ke capture hone ke baad, usmein kitni der ka time delay tha. Aise hi, receiver multiple satellites se signals capture karta rahta hai aur un signals ke time delays ko calculate karke apni accurate position find out karta hai.
