  Programming is like talking to computers using their own language, almost like having a superpower. You provide step-by-step instructions, and they follow along to make things happen. Now, you might wonder why programming is so important. Well, think about all the technology around you - your smartphone, social media, and most things you use daily. They all rely on code, which tells the devices what to do. It's like the ultimate tool for making digital things work. One of the most essential programming languages is Python. It's friendly, easy to understand, and very versatile. Python doesn't use confusing words or tricky rules. It focuses on being simple and straightforward for users. There are several concepts and techniques in Python that you need to know and understand if you are new to the programming world. The concept of Polymorphic behavior is one of them. This blog will introduce you to the concepts and techniques to achieve  Polymorphism in Python .  We will al...

Many concepts are extremely vital in software development. However, the two concepts, i.e., multithreading and concurrency, play a pivotal role in the world of software development. In the software development world, performance and efficiency are paramount, This article will talk about two critical concepts, i.e., Multithreading and concurrency.  We will go deep into the fundamentals of multithreading by keeping a specific focus on  multithreading in Java  and explore how  online Java ide editors  have made it easier for developers to experiment with and master these concepts. Without any further ado, let’s get started! Understanding Multithreading and Concurrency As the name suggests, multithreading is the practice of executing multiple threads concurrently within a single process. You can consider a thread as an independent path of execution within a program.  In contrast, Concurrency is the property of a system in which multiple independent tasks are ex...

  If you are a newbie or a database professional, this blog post will help you! Database management systems are the systems that are used to manage, store and run data-related queries. RDMS (relational database management systems) in DBMS is the program that is used to maintain relational databases.  Furthermore, in RDMS, the term PostgreSQL plays a crucial role. It is a stalwart champion known for its robustness, extensibility, and open-source nature. Thus,  practicing PostgreSQL interview questions  is vital when going for an interview.  So, whether you're a database professional looking to master this powerful tool, this blog post will help you. We will delve into the depths of PostgreSQL, its significance, and how to prepare for it effectively. Without having any further ado, let’s get started! What is PostgreSQL? PostgreSQL is an advanced open-source object-relational database system.  It is often called "Postgres."   It was developed to provide a...
