SQL vs NoSQL Databases

When it comes to choosing a database for your project, the options are countless. That being said, most databases will fall into two categories: SQL and NoSQL databases. Both have their pros and cons but first let’s understand the meaning of each term. # SQL **SQL** is an acronym for **‘Structured Query Language’.** It’s a domain specific programming language that is used for CRUD operations within a RDMS (Relational Database Management System). It is mainly used for managing structured data where we have a relationship between various entities and variables of the data. SQL consists of various types of statements that are used to query the data stored in the databases. ## DML - Data Manipulation Language These types of statements are used for performing the CRUD operations in the database. Examples of common DML commands in SQL are **SELECT, INSERT, UPDATE and DELETE.**

Personal Management

In our daily life, we are always in a hurry to get many things done, and sometimes it is very difficult for us to manage these processes. As long as the work we have to do has a deadline, we don't have any problems about when these works should be completed. Of course, we have a lot of difficulties in planning this, but the homework and tasks given to us since we were little, teach us to keep up with the deadline.

Threats in Cyberspace

We live in a digital world where life beyond the web is too hard to think of. Our personal lives, work lives, and finances all in the process tend toward the world of the internet, mobile computing, and electronic media. Humans are just one click away to attain knowledge about every little thing. Smartphones and Laptops seem to be a part of daily life, internet usage also expanded. Unfortunately, the overall aspects make us more vulnerable than ever to malicious attacks, invasions of privacy, fraud, and other unpleasantries. In March 2013, the nation’s top intelligence officials cautioned that cyber-attacks and digital spying are the top threat to national security, eclipsing even terrorism. Reports suggest that by the year 2021, the total loss in the global economy would be US$6 million due to cyber-attacks and cybercrime would cost $10.5 Trillion annually by 2025.

GitHub Workflow

Git and GitHub is a must for any developer. At some point of your path, especially if it is related to the software industry, you will definitely hear of “Git” and “GitHub”. Even if you haven’t heard about them, I will briefly touch on what those terms are. After that, I’ll go into further details of gitflow which is a branching strategy that helps management of your code. Git is a version control system which tracks your code for any changes and records it. So it gives an opportunity to revert the changes you made mistakenly, or make a version update after fixing the issue. Beside that, it is possible to collaborate on the project with team members as they can also contribute to the source. GitHub cannot be imagined without git, so it is the main component of the website. It hosts “more than 190 million repositories (including at least 28 million public repositories)”. Those repositories may consist of the source code of a software , or even book contents. They provide some features such as pull requests and task management.

A user may want to connect to a VPN to stream a movie that is unavailable in their current location or maybe they want to connect to a company network while they are at home and working.
