Introduction to SQL? SQL (Structured Query Language) is a programming language designed for managing and manipulating relational databases. It provides a standardized way to interact with databases, allowing users to create, retrieve, update, and delete data stored in the database. SQL is widely used in various applications and is considered the standard language for working with relational databases. The primary goal of SQL is to provide a declarative approach to database management. Instead of specifying how to perform operations on data, SQL focuses on defining what data to retrieve or modify. This makes SQL a powerful and efficient language for handling large datasets. SQL operates on tables, which are structured collections of data organized into rows and columns. The language provides a set of commands or statements to perform various operations on those tables. Some of the most commonly used SQL statements include: 1. SELECT: Retrieve data from one or more tab...

Introduction to Go? Go (aka Golang) is one of the fastest growing programming languages. It's open-source language released by Google in 2009 and created by Ken Thompson (designed and creators of UNIX and C), Rob Pike (co-creator of UTF 8 and UNIX format), and Robert Griesemer. It's a multi-purpose programming language specifically designed to build scalable and faster applications. Although Go has been around for quite a while now, it didn't manage to get wide adoption by developers until more recently due to the proliferation of cloud computing and microservices. Today, Go has been widely used by major companies such as Google, Dropbox, Uber, and Dailymotion. Go is a statically typed, concurrent, and garbage-collected programming language created at Google in 2009. It is designed to be simple, efficient, and easy to learn, making it a popular choice for building network services, web applications, and command-line tools. Go is known for its support for concurrency,...

Introduction to Ruby? Ruby is a powerful and dynamic programming language known for its simplicity and elegance. It was designed to prioritize developer happiness and productivity, emphasizing huma-friendly code syntax and readability. Ruby has gained popularity for its flexibility, object-oriented nature, and extensive libraries, making it suitable for a wide range of applications, including web development, scripting, data analysis, and more. Yukihiro Matsumoto, also known as Matz, created Ruby in the mis-1990s with the goal pf combining the best features of other programming languages. As a result, Ruby has borrowed concepts from languages like Perl, Smalltalk, and Lisp while incorporating its own unique features. One of Ruby's key strengths is its focus on object-oriented programming (OOP). In Ruby, everything is an object, including numbers, strings, and even classes themselves. This object-oriented approach simplifies code organization and allows for easy ...
