It a implementation of key-value database using python that perform create , read and delete operations
Problem: Build a file based key-value data store that support ->create ->read ->delete
operations , the data stored must be locally stored in the system .
The database is stored locally in json format I have taken 2 databases, one is master database and the other is temporary database temporary data will store all the operations for one single process .
I have taken key as a string and pair as a number , we can also modify the code so that pair becomes a string,number,list,dict...or any data structure that is supported in the dictionary . I have also included timeout concept
#Wanted to show that we can use what ever we want to store in key-value data store
#In Code that i have implemented ,string key and int value is what i have used
dict={}
dict["name"]="sumit" #value is string
dict["age"]=16 #value is int
dict["Subject"]=["Python","C++"] #value is List
dict["random"]=["abc",1,["2",3]] #value is list within list
dict["inside_dict"]={1:2} #value is dictionary
print(dict)
Output: {'name': 'sumit',
'age': 16,
'Subject': ['Python', 'C++'],
'random': ['abc', 1, ['2', 3]],
'inside_dict': {1: 2}}Also ,I have implemented all the code in same notebook , if we want to make a library then we have to create 2 .ipynb notebook one with all the functions and another one will contain all the instances and calling of these functions
#For example : Make 2 .ipynb notebook , save it in one directory A.ipynb and B.ipynb
#If we want to use A.ipynb as library for B.ipynb
#we can import A file as Library in B using this simple one line code
%run A.ipynb
