Advantages of DBMS over FILE System

  • Data Redundancy and inconsistency: Redundancy is the concept of repetition of data. Each data may have more than a single copy. The file system cannot control the data as each user keeps the data to run different applications. If two users are maintaining the data of the same file to run different applications, then if one users changes the data, it doesn't reflect in files used by the other users which can lead to inconsistency of the data. DBMS controls redundancy by maintaining a single repository of data that is defined once and accessed by many.
  • Data sharing: The file system doesn't allow to share the data and sharing is too complex. DBMS allows easy sharing of data due to centralized system.
  • Data concurrency: Concurrent access to data means, more than one user accessing the data. Anomalies occur because changes made by a user can be lost because of the changes made by the other user. The file system doesn't provide any facilities to stop anomalies. DBMS provides locking system to stop anomalies.
  • Data searching: DBMS provides inbuilt searching operations. The user has to write a very small query to retrieve the data.
  • Data integrity: There may be cases, where some constraints need to be applied to the data before inserting it into the database. DBMS maintains data integrity by enforcing user-defined constraints on data by itself.
  • System Crashing: DBMS will have recovery system which retrieves the data.
  • Data Security: DBMS has special features that help providing shielding to the data.
  • Backup: It creates a Backup subsystem to recollect the lost data if required.
  • Easy Maintenance: It is easy to maintain because of it's centralized system.

THREE LEVELS OF DATA INDEPENDENCE

Image
THREE LEVELS OF DATA INDEPENDENCE It divides the entire system into three inter-related but independent modules: Physical Level: Here, information about the location of database objects in the data store is kept. Various DBMS users are unaware of the locations of these objects. The Physical level of database describes how the data is stored in secondary storage devices such as disks and tapes. Conceptual Level: Here, data is represented in the form of various tables. For Example, STUDENT database may contain NAME and COURSE tables, but the users are unaware of their storage. It refers to what kind of data to be stored in a database. External Level: Here, it specifies the view of data in terms of conceptual level tables. It can generate different views of the database for different users. It focuses main on data abstraction.  Data Independence: It means change of data at one level must not affect the another level. Physical Data Independence: Any change in the physical location of the t

Python Syntax, Comments, Variables, Indentation

Execute Python Syntax As we learned in the past page, Python grammar can be executed by composing straightforwardly in the Command Line: >>> print("Hello, World!") Hello, World!  Or on the other hand by making a python record on the server, utilizing the .py document augmentation, and running it in the Command Line: C:\Users\ Your Name >python myfile.py  Python Indentation Space alludes to the spaces toward the start of a code line. Where in other programming dialects the space in code is for lucidness just, the space in Python is vital. Python utilizes space to show a square of code. if 5 > 2 :   print ( "Five is greater than two!" )   Python Variables In Python, factors are made when you relegate a worth to it: x = 5 y = "Hello, World!"   Python has no order for proclaiming a variable. Comments Python has remarking capacity with the end goal of in-code documentation. Remarks start with a #, and Python will deliver the remainder

Python-HackerRank Problem List Comprehensions

Problem Print a list of all possible coordinates given by (i,j,k) on a 3D grid where the sum of i+j+k is not equal to  n. Here, 0<=i<=x;0<=j<=y;0<=k<=z. Please use list comprehensions rather than multiple loops, as a learning exercise.  Source Code   if  __name__ ==  '__main__' :     x =  int ( input ())     y =  int ( input ())     z =  int ( input ())     n =  int ( input ())      print   ([[ a , b , c ]   for  a  in   range ( 0 , x+1 )   for  b  in   range ( 0 , y+1 )   for  c  in   range ( 0 , z+1 )     if  a + b + c != n  ])
