SQL is a key cog in a data science professional's armory. I'm speaking from experience - you simply cannot expect to carve out a successful career in either analytics or data science if you haven't yet picked up SQL.

And why is SQL so important?

As we move into a new decade, the rate at which we are producing and consuming data is skyrocketing by the day. To make smart decisions based on data, organizations around the world are hiring data professionals like business analysts and data scientists to mine and unearth insights from the vast treasure trove of data.

And one of the most important tools required for this is - you guessed it - SQL!



Structured Query Language (SQL) has been around for decades. It is a programming language used for managing the data held in relational databases. SQL is used all around the world by a majority of big companies. A data analyst can use SQL to access, read, manipulate, and analyze the data stored in a database and generate useful insights to drive an informed decision-making process.

In this article, I will be discussing 8 SQL techniques/queries that will make you ready for any advanced data analysis problems. Do keep in mind that this article assumes a very basic knowledge of SQL.All Rights Reserved

The Sacred Wolf Pact by Nananana989

Werewolves exist, but none of that sparkly vampire bullshit. In this world, we are divided into two categories, human, and wolf. Wolves are divided into four categories as well. Alpha, the leader of the pact, beta, the most trusted followers, normals, those who came use their abilities, and omegas, completely average. Unfortunately, every century or so, a omega is born that is extremely fertile, able to give birth to many wolf children. Its bad enough to be attacked when in heat, but for that to happen? Yet, we sill follow the rules of mates, so this rare omega ends up with only one person. And it's only when the omega is in heat can they have children, male or female. Over century has gone by without a sight of this rare Omega. At least, that's what I thought. It's not until I go into heat for the first time, when I'm seventeen, that I realize that it's me, and my mate......... My mate isn't the least bit friendly. This story is mostly fluff, so yeah. Lots of kisses and fluffy wolf babies. Little angst. It's also very short. After the epilogue, the story will continue in a sequel. So, if you want more emotions than this, stay tuned for that.

Investigating the Alpha by Ruecker34

"Order for table ten!" The cooked called, i dashed over grabbing the tray and a tray holder heading out to the table. My name is Juniper Marie Scotts. I'm 21 years old and live in a small down in South Carolina. I have three jobs and am a full time College student working on my masters Degree in Forensic science. I'm working on becoming a crime scene investigator. ------- "Sir! Rogues have been spotted outside fifth and Wakarusa at a diner! We have intel saying they are connected to a series of crimes happening all over town." I sighed resting my head in my hands. "Take a squad team out there, dont engage unless given orders otherwise! Jason and Matthew I want you to round up any pack members out there that aren't warriors and get them back to the house." The war between us and rogues has been going for decades. My father fought in it, my grandfather fought in it, my great grandfather fought through it. We dont know how long exactly this has been going on nor what started the stupid thing. There's talk that it was started between our pack and another over territory. They wanted to expand onto our land and we didnt agree. We fought, there alpha was killed and all of them became rogues. "Sir are you leading in the investigation into these rogues?" i sighed, exhausted and so tired of this. "I'm on my way." -------- Juniper was your average hard working student. Part time bartender, part time waitress, part time undercover cop. Living with her grandfather and working to get themselves into a better place. She works two jobs as part of undercover work her police department is investigating in the terms of gang violence. She didnt plan on getting wrapped up in gang disputes in town, until the night a fight broke out in the diner and she met Dean. Little does she know who is also the chief of police no one ever see's.

Omega and the beast by AmenRocks1

You know when people say how it's like love at first sight when seeing their love for the first time? You look him in the eyes and know he's the man of your dreams. Bullshit! There's nothing that would ever change my mind about the so-called love of my life! Sure, the first time I saw him he was annoyingly handsome with his proud demeanour & defined cheekbones. That penetrating look of his made my knees weak. With shiny black shoes and a Dracula coat with a hairstyle as shiny as his Santorini black jaguar. But the first thing I thought when I saw Reed Ramon Hook the third was, what a twat! A proud rich dipshit who thinks he can own everything. No one could ever say no to this noble twat! You may wonder why I roast the love of my life. But is there anyone who has the permission to do so it must be his own omega, right? Yes, I forgot to mention how this perfect dipshit to a hunkalicious twat is the alpha of the Hookhill pack. To be honest, I had no idea what that meant. Nor did I know how a man can bend down and suddenly stand on four paws, growing a tail! It came as news to me! But the biggest shock was how it turned out that I also can warp into a beast with a furry tail above my ass! From being an unsuccessful yet optimistic guy without an income but with a sense of sarcasm, to then kind of belong to town's richest man, becoming the subject of an Alpha battle. I understand if you're confused. So was I! But let me rewind the tape and take everything from the beginning. Lean back and embrace your sassiness! Because sassiness rules and is needed when dealing with a twat! Heads up! This book contains mature themes like smut, mpreg, violence & bad language. It addresses important topics like rights & gender. I want to highlight these themes but don't intend to devalue anyone stereotypically. It's a fictional story intended to entertain but with important topics. Trigger warning for abusive-like violence and oppression, mainly towards the end.

The Aeon of Dragons: A Tale of Epic Fantasy & Sci-fi by MikoVesper

Eighty thousand years into the future, Earth is no more. This world is now called Lokar-a realm of strangeness, where humans struggle to survive alongside elves, orcs, goblins, vampires, merfolk, and dragons. Born from the genetic-engineering science of our present age, these species now fight to rule a world of sword and sorcery, war and blood. But Lokar's story is more than this. In orbit, the Sky People dwell-a breakaway civilization from humanity's forgotten past. Mythical and unseen, save for the drifting lights of their stations in the night sky, their name is whispered in reverence and fear. To most, they are only a legend. Until the sky falls. When a steel ship crashes onto Lokar, myth becomes reality. From the wreckage emerges Morse, a girl named with fire-orange eyes, bearing secrets as ancient as Lokar itself. Drawn by adventure, a young Lokari named Jason must join forces with this enigmatic fire-eyed girl to uncover the mysteries of their intertwined pasts and face a destiny neither could have imagined. The fate of Lokar and the stars hangs by a thread. As the veil between legend and history tears away, a truth long buried will rise to shape a future yet unwritten. These secrets have been whispered for millennia. Now, Lokar must listen. ------- Note: I publish a chapter 3 times per week on Mondays, Wednesdays, and Fridays. I also do all of my own art, which you can see in each chapter. If you'd like to see more art, especially the stuff I can't publish here (*wink wink*), you can find that on my Patreon. I believe in world-building and rich characters. I also believe in big ideas. There is a bit of steamy interaction between the characters, but it's not the main focus!

The Alpha ~ Mikey x Takemichi by Nightfurychild

Alpha = Have the say over the whole group and are therefore higher in rank than others. Beta = Are second in rank. Make decisions with the alphas of the group. If the Alpha is gone, the Beta takes over. Delta = They are known to be rather calm/laid back in character. They are good at putting themselves in scenarios and can also resolve conflicts well. Gamma = Gammas are the 'protectors' of the group. They notice when something is wrong and try to resolve it as a group, or to let the first rank (Alpha) know. Gammas often take the role of mother/father in the group for this reason. And then the Omegas come... They are shy, easy to dominate and are the 'victims' in the group. But there are groups that are on the law: "Omegas are not important and don't need to be treated well." and treat everyone the same because they feel that everyone should be treated the same. ______________ ~What happens in the story does NOT happen in the anime. ~boyxboy ~Comical humor ~Perverse ~TRIGGER WARNING~

Knowledge and Divinity Book 2 : Strength by ShahSoumil

What, according to you, are the most important aspects of a strategy, of a plan? I say, it's the 'brain' and the 'muscle'. For a plan to be successful, it has to be well thought out. And at the same time, you cannot succeed without the strength to do so. Imagine that you're stuck in the middle of a conflict you cannot escape. You can only choose a side. Would you have the strength to do what's right no matter the consequences? Could you outsmart the plan? *** Suddenly, I felt a surge of emotions from Bear's mind, emotions of fear, confusion, hatred, hopelessness, desolation, anger that he was hiding from all of us even when we were in his mind. "It's you, Sakhi! You're the Gods' biggest joke on my life. You're the irony I'm sure they are laughing upon right now!", he said. "What do you mean?", I asked. "I used to love you" Conner illustration by Llyn Wildr

Psychopathic (BoyxBoy) by ApatheticWickedWitch

Omegas are extremely rare, so Eli was used to being treated differently when he moved to a new town and pack. In that town there's a gorgeous alpha, a beautiful beta, and a dangerous psycho so hellbent on stealing him away. This story is a little bit different. More twisted and unexpected than one would initially assume. Not everything is what it seems.

"You Got Me, I Got You" BNHA by seokgayysus

In a society where you can get harassed for being an omega or quirkless, someone who is born as both end up living miserably. A male being born as an omega may as well be a death sentence in this society; quirkless or not. Izuku is, unfortunately, one of these individuals. Izuku has lived his whole life being teased and bullied for being quirkless and not acting dominantly like any future alpha or beta. When he presents as an omega and has his first heat when he is 14, he decides enough is enough and takes heat suppressors to fake being a beta. Until he forgets to take the heat suppressors the day after the UA Sports Festival and thinks he's sick. Todoroki, an alpha decides to stay with him while everyone else decides to go out together. Neither of them expected their lives to change forever. Part 1 of The ABO Series -tododeku -omegaverse -trigger warnings -angst, fluff, and smut (not centered around it though)

bnha x male reader •the hidden omega• by neeuqqueen11

Being the most "i-don't-give-a-fuck" person, once the school finds out that you're an Omega, shit gets real. You're very popular, and the girls are always chasing after you. But when a specific someone gets put in the Omega group, everyone thinks it's joke. Because you're obviously an Alpha. Wrong.
