Metadata : Get To Know Your Dataset

-

 


Price tags provide metadata about the product they are attached to.


The "meta-" part of metadata means "beyond" or "transcending."

So, metadata is like extra information that goes beyond the main data.

For example, think about your name, personality type, height, and weight. 

These are all things that help people know more about you.

Here's an example some of my metadata:

Name: Toni-Marie Noel
Personality Type: ENTJ
Height: 5 feet 6 inches (167.64 cm)
Weight: 129 pounds (58.51 kg)
Favorite Pastry: Currants Roll 


I first heard about metadata at work, and it's becoming a really important aspect of my role.

But why is metadata important in the first place?

Searchability

Imagine searching for George Orwell's 'Animal Farm' in a library filled with books lacking labels on their covers. A nightmare, I know! That's why I actually judge books by their cover.

Search Engine Optimization 

Utilizing the correct keywords can lead to a staggering 75% of clicks going to websites on the first page of Google's search results for a given topic, while websites on the second page receive just around 6% of clicks.

Version Control

Metadata is the document that keeps track of who made what changes and when, preventing chaos. It's like having a time-traveling notebook to keep your group work on the same page. 

Personalization 

Ever wondered why YouTube feels like your personal stalker, always recommending videos from creators you've watched before? 

You scroll and keeps whispering, "Hey, remember that ASMR video you loved? Here's another one!"

0 to 100: A Reflection

-
Image
What's 10 x 10? I started this blog on February 4th, 2023—almost two years ago (wow, I just checked!)—and I must say, writing consistently is a challenge that I gladly took on. Writing has been a constant theme in my life. It got me through my rebellious teen years and straight into adulthood (which, to be honest, I still have a hard time accepting). Many people ask me, "How do you do it?" To that, I say: I enjoy it, and I have a great support system. Today, I want to take a moment to reflect and give thanks—to those who read my posts, those who point out my typos, and especially to my dad, who always asks, "Toni, did you post yet?" But let’s be real: doing 100 of anything is difficult—whether it's 100 pull-ups or developing 100 apps. Even when you’re passionate about something, there are days when you just don’t have the energy or inspiration. And that’s okay! You just have to keep pushing forward—through the valley of despair, even when no one is watchin...

Scheduling Algorithms

-
Image
Hickory Dickory Dock! Today's post is inspired by my sister (AKA Dr. Dan Dan), who recently asked me for help scheduling appointments for her patients. As a budding dentist, it's imperative for her to find patients and fit them into her already busy schedule. Sometimes, patients cancel, and she faces a swiftly approaching deadline. Just like a computer prioritizes tasks based on system resources, my sister must prioritize her patients based on the complexity of the procedure and the time available. For example, root canals require more time and expertise than a simple cleaning, much like certain programs demand more of a computer's memory and processing power. The Task Manager in your computer is a program that manages all the active processes, or tasks, running at any given time.  It prioritizes tasks based on importance, ensuring that the most immediate requests—like opening Google Chrome—are allocated more system resources. With that being said here are some common sched...

Make Your Screen Time Matter

-
Image
People swipe on their phones an average of 2500-5000 times per day   With the TikTok ban looming in the U.S. amidst national security concerns, I believe we should also be asking a deeper question:  What are we allowing to capture our attention? Social media isn’t just profiting from our data—it’s also draining our limited time and energy! Isn’t it funny how we all wonder why we can’t get things done, yet we constantly allow ourselves to be distracted? As someone who recently deactivated their Instagram account, I’ve realized how much passively consuming endless videos— ones I never even searched for —has negatively impacted my well-being. Whether it was comparing my life to those who could afford trips to Europe or staying up late searching for something to share with friends, I realized I was consuming content without purpose. In a time of shrinking attention spans, the ability to focus and take action is more valuable than ever. Now, I’m not saying entertainment is bad, but...

Sharks, Dogs and Biases

-
Image
Tens of millions of people suffer from dog bites each year globally, compared to just 50–80 shark bites. As a data professional, I am expected to interpret data and provide stakeholders with insights in the form of a story. Many refer to this skill as "critical thinking." While that is valuable, one must also question how they arrived at their conclusions in the first place. According to Wikipedia, a bias is a disproportionate weight in favor of or against an idea or thing, usually in a way that is inaccurate, closed-minded, prejudicial, or unfair. I gained a deeper understanding of biases during an Organizational Behavior course I took in university, and I briefly mentioned it in Blog Post #8, which discusses data-driven decision-making. Beyond numbers in a database, biases can lead to poor decisions in the real world. For example, it is statistically more likely to be bitten by a dog than by a shark; however, availability bias caused authorities in Tobago to place a bounty ...

Value Creation

-
Image
Money grows on trees—the tree is a metaphor for your mind. Defining a problem is the first step to solving it, but have you ever considered the value your solution will create? Before jumping into problem-solving, it's crucial to ask: Is this the right problem to tackle, and is solving it worth the cost? As professionals—especially in tech—it’s easy to fall into the habit of building solutions without pausing to assess whether the effort aligns with the value it delivers. For example, imagine spending weeks building an automated self-watering system for a cactus. Sure, it’s a cool project, but was it really worth the time and resources? After all, a cactus only needs watering once a week, and it would take less than a minute to do it yourself. Sometimes, solving the problem manually is the most effective and resource-efficient option. Your salary is directly linked to the value you bring to a company, and time and energy are finite resources. How we choose to allocate them signif...

The Algorithm : Musk's Mental Framework

-
Image
A Decision Tree Today’s post is inspired by Elon Musk, the captivating biography by Walter Isaacson. At 688 pages, it’s a deep dive into the mind and methods of one of the most transformative figures of our time. Over the past two weeks, I’ve spent my early mornings absorbing Musk’s journey—and it’s left me contemplating the driving force behind his success.  What is the “algorithm” that powers his extraordinary ventures? Though his leadership style is unconventional, it’s undeniably effective. Musk has co-founded revolutionary companies like PayPal, SpaceX, and Tesla, each of which has disrupted its industry and pushed boundaries.  But what makes him tick? What’s the underlying formula behind his ability to juggle ambitious goals, relentless innovation, and transformative leadership? The Algorithm: Musk's Mental Framework As detailed in Isaacson’s biography, Musk often speaks of a personal algorithm—a mental framework that guides his decision-making process.  The algorit...

Learning Something New: EDA on Guitars

-
Image
This is an acoustic guitar Today’s post is inspired by my childhood dream of learning to play the guitar. For years, I’d daydream about strumming chords and creating melodies, but it always felt like something I’d do “someday.”  That day finally arrived when I jokingly shared this dream aloud, and my dad decided it was time to make it a reality. Yesterday, he surprised me with my first guitar—a sleek, acoustic guitar with nylon strings. The moment I picked it up, I was both excited and intimidated. I immediately started tuning it and spent an hour practicing E-minor and A-minor chords.  My fingers quickly grew sore, and faint ridges were left behind from pressing on the strings—but I didn’t mind.  There was something unexpectedly soothing about the vibration of the strings resonating through the guitar, as if the instrument itself was encouraging me to keep going. Learning a new skill is a reminder of how persistence pays off. I know that mastering the guitar will take ti...

Key Performance Indicators

-
Image
  Every day, we pay attention to things that keep our lives running smoothly, like making sure our phone battery is charged.  Today's post is inspired by a presentation I did with my team around KPIs, short for Key Performance Indicators.  I've created many dashboards in the past, but I hadn't fully understood the significance of KPIs. After questioning the significance of these numbers and taking a LinkedIn Learning course, I gained a clearer perspective on the topic.  Imagine pilots in a cockpit: If they focus only on one sensor, they could miss other crucial information and risk a crash. On the other hand, if they try to monitor every single indicator at once, they’d be overwhelmed and could make critical errors. You see, the reason why it's called a key performance indicator is that you must be intentional with your selection process so that you get the desired result. You get what you measure! After completing the course, I realized how essential it is to select...

Data-Driven Case Study : Barnes & Noble

-
Image
Barnes & Noble's beginnings can be traced to 1873 Today's post is inspired by an article I read about the recent resurgence of Barnes & Noble, the iconic American bookstore chain. As a bookworm, I found the story especially appealing. Back in secondary school, I used to imagine working in a bookstore or a library during summer vacation, surrounded by shelves of book. It seemed like a dream job. Barnes & Noble originally set itself apart with vast, well-stocked stores and an enormous selection of titles. This approach attracted a steady stream of customers and fueled the company’s rapid expansion. But then Amazon arrived, making it possible to order a book with a few clicks and have it delivered to your doorstep. The shift to online shopping left many of Barnes & Noble's stores eerily empty. Enter James Daunt, the managing director of Waterstones, the largest bookseller in the United Kingdom. Tasked with turning Barnes & Noble around, he brought a fresh p...

Data Stacks: Google, Microsoft and Amazon

-
Image
Stack: a pile of objects, typically one that is neatly arranged. Conversations about tech preferences tend to get heated, whether it’s Apple vs Android, Windows vs macOS, or the eternal debate about pineapple on pizza. But lately, I’ve found myself drawn to something : data stacks. Specifically, why do organizations choose Microsoft, Amazon, or Google as their cloud platform? Microsoft has quietly become the stack of choice for many enterprises, but why? What’s the real difference between AWS and Azure, and is one easier to learn than the other? More importantly, are we so locked into these proprietary tools that we’re missing out on better, open-source alternatives? Learning a new tool takes time, and that time investment often keeps us tethered to one ecosystem. But with so much innovation happening, it’s worth asking: Are we keeping our minds open to what’s out there? To answer these questions, it helps to ...
