I appeared for an interview in Dec 2024.
Different types of backups include full, incremental, differential, and snapshot backups.
Full backup: backs up all data in the database
Incremental backup: backs up only the data that has changed since the last backup
Differential backup: backs up all data that has changed since the last full backup
Snapshot backup: creates a point-in-time copy of the database
Offline reorg requires database to be offline, while online reorg can be done while database is still accessible.
Offline reorg requires exclusive access to the database, while online reorg can be done concurrently with database operations.
Offline reorg is typically faster as it doesn't have to deal with concurrent transactions, while online reorg may take longer but allows for continuous access.
Offline reorg is usually...

Inheritance is a mechanism in object-oriented programming where a class can inherit properties and methods from another class.
Inheritance allows for code reuse and promotes code organization.
The class that is being inherited from is called the parent or base class.
The class that inherits from the parent class is called the child or derived class.
The child class can access all the public and protected members of the par...

Django request response cycle is the process of handling a request and generating a response in Django web framework.
Client sends a request to the server.
The request is received by the Django server.
Django uses URL patterns to match the requested URL to a view function.
The view function processes the request and returns an HTTP response.
The response is sent back to the client.
Django signals allow certain senders to notify a set of receivers that some action has taken place.
Signals allow decoupled applications to get notified when certain actions occur elsewhere in the application
They are used to avoid coupling between applications
Signals are defined by providing a receiver function which gets called when the signal is sent
Example: A signal can be sent when a new user is created, and a recei...
Lists and tuples are similar but tuples are immutable. Arrays are fixed size while lists are dynamic.
Lists and tuples are both used to store collections of data.
Tuples are immutable, meaning their values cannot be changed once created.
Lists are dynamic and can be resized during runtime.
Arrays are fixed size and can only store elements of the same data type.
Lists and arrays can be indexed and sliced to access specific e...
Private variables are defined using access modifiers to restrict their access within a class.
Use the 'private' keyword to define a private variable
Private variables can only be accessed within the class they are defined in
Private variables are often used to encapsulate data and prevent direct access from outside the class
Oops concept is a programming paradigm based on the principles of abstraction, encapsulation, inheritance, and polymorphism.
Abstraction: Hiding the implementation details and showing only the necessary information to the user.
Encapsulation: Binding the data and methods together to protect the data from outside interference.
Inheritance: Creating a new class from an existing class to reuse the code and add new features.

A decorator is a design pattern that allows behavior to be added to an individual object, either statically or dynamically.
Decorators wrap an object to modify its behavior.
They provide a flexible alternative to subclassing for extending functionality.
Python has built-in support for decorators, which are denoted by the @ symbol.
Examples of decorators include @staticmethod, @classmethod, and @property.
1.Reverse a list
2.find pairs from a list sum of which is equal to an integer k.

Pull is when the client initiates the request for data, while push is when the server sends data without a request.
Pull: Client initiates request for data
Push: Server sends data without request
Pull: Used in polling mechanisms
Push: Used in real-time communication systems
Pull and fetch are both Git commands used to update a local repository with changes from a remote repository, but they have different behaviors.
Pull: updates the current branch with changes from the remote repository and merges them into the local branch.
Fetch: downloads changes from the remote repository to the local repository, but does not merge them into the local branch.
Pull is a combination of fetch and merge, wh...
