Network Model in DBMS in hindi

Network Model ek database management system (DBMS) ka data model hai, jo data ko network-like structure mein organize karta hai. Ye model hierarchies ki jagah graph structures ka upyog karta hai. Network Model 1960s aur 1970s mein prachalit hua tha, lekin baad mein Relational Model ke aane ke baad iska istemal kam ho gaya.

Network Model mein data ko records aur relationships ke network ke roop mein represent kiya jata hai. Data records ko nodes aur relationships ko edges ke roop mein darj kiya jata hai. Is model mein ek record multiple relationships ke part ban sakta hai aur ek relationship multiple records ko jod sakta hai.

Kuch mukhya tatva Network Model ke hain:

  1. Records (Nodes): Network Model mein data records ko nodes ke roop mein represent kiya jata hai. Har node ek specific entity ko darshata hai, jiske properties (attributes) ko fields ke roop mein darj kiya jata hai. Har node ko ek unique identifier ke madhyam se identify kiya jata hai.

  2. Relationships (Edges): Relationships records ke beech mein connections ko darshate hain. Ek relationship multiple records ko jod sakta hai. Har relationship ko ek unique identifier ke madhyam se identify kiya jata hai. Relationships ke through records ke beech ki navigation aur access kiya jata hai.

  3. Owner Records: Network Model mein har record ka ek owner record hota hai. Ek owner record ke multiple member records ho sakte hain. Is tarah ke hierarchical structure se relationships ko darshaya jata hai. Owner record se member records tak pointers ke madhyam se pahuncha jata hai.

  4. Set-Type Relationships: Network Model mein relationships ko sets ke roop mein represent kiya jata hai. Sets multiple records ko jodte hain, aur set type relationships allow karte hain ki ek record multiple sets ke part ho sake. Isse ek record ko multiple relationships mein shaamil hone ki anumati milti hai.

Network Model ke faide hain ki isme complex relationships, jaise many-to-many relationships aur hierarchical relationships, ko represent karne mein saksham hai. Isme data redundancy kam hoti hai, kyonki records aur relationships ko ek baar hi store kiya jata hai. Data retrieval aur data manipulation mein flexibility milti hai, kyonki records aur relationships ko navigational paths ke through access kiya jata hai.

Halaanki Network Model ek samay mein prasiddh tha, lekin iska istemal aajkal kam ho gaya hai. Relational Model aur dusre advanced data models, jaise ki Object-Oriented Model aur Document Model, ka adhik istemal hota hai. Ye models data organization, data retrieval, aur data manipulation mein adhik flexibility aur ease of use pradan karte hain.
