What is data independence in hindi

Data independence, ek database management system (DBMS) concept hai, jisme data structures, data formats, aur data organization ke changes ke bina data ko access aur manipulate kiya ja sakta hai. Iska matalab hai ki database schema ke changes ya physical data storage ke changes ke baad bhi, user applications ko data ko retrieve, modify, aur utilize karne ke liye koi impact nahi padega.

DBMS के ये Topics के बारे में जानें :-

Data independence ke do pramukh prakar hote hain:

  1. Logical Data Independence: Logical data independence kehta hai ki database schema ke changes, jaise ki table structure, relationships, aur constraints ke changes, user applications par koi asar nahi padna chahiye. Agar schema mein changes hote hain, to user applications ko kewal schema definition ko modify karne ki jarurat hoti hai, data retrieval aur manipulation queries ko nahi.

  2. Physical Data Independence: Physical data independence kehta hai ki physical data storage aur organization ke changes, jaise ki data file format, storage devices, ya indexing techniques ke changes, user applications par koi asar nahi padna chahiye. Agar physical storage mein changes hote hain, to user applications ko kewal physical storage details ko modify karne ki jarurat hoti hai, data retrieval aur manipulation queries ko nahi.

Data independence ka pramukh labh yeh hai ki ek bar database schema ya physical storage ko modify karne par bhi, user applications ko us par depend na karke, uninterrupted access aur functionality milti hai. Isse database maintenance aur evolution ko asan banaya jata hai, kyonki changes ko ek isolated level par implement kiya ja sakta hai.

Data independence ke madhyam se, DBMS database design aur architecture ko evolve karne ki flexibility deta hai, bina existing applications ko disturb kiye. Isse database scalability, performance, aur maintenance ko improve karne me madad milti hai.
