<p>Data Pipeline is important when working with data from different parts of the world, specifically Extract Transform Load is a popular framework for data pipelines.</p>
<h3 id="heading-how-this-applies-to-healthcare"><strong>How this applies to healthcare</strong></h3>
<p>Data starts</p>
<ul>
<li><p><strong><em>Extraction</em></strong> - when a patient shows up at the reception to book an appointment due to signs/symptoms presentation, then</p>
</li>
<li><p><strong><em>Transform</em></strong> - the first medical point of contact is with nurses, for vital signs checks where important data related to the key organ functionality is recorded in a file related to that patient, before</p>
</li>
<li><p>the doctor sees this patient then a medical diagnosis would be arrived at ( = what went wrong in medical terms) and recorded</p>
</li>
<li><p><strong><em>Load</em></strong> - next steps such as tests are being recorded under this same patient electronic file while</p>
</li>
<li><p>the patient moves from one department to another</p>
</li>
<li><p>NB: A patient diagnosis can be changed multiple times as much data is being derived from other departments eg haematology lab.</p>
</li>
</ul>
<ul>
<li><h3 id="heading-1-analogy"><strong>1 analogy</strong></h3>
<p>  In the space of cancer tech, there are a lot of similarities in diagnosis which helps in research but a lot of healthcare data isn’t readily available due to laws surrounding it.</p>
</li>
<li><h3 id="heading-1-question-im-exploring"><strong>1 question I’m exploring</strong></h3>
</li>
<li><p>How fast would solutions be derived in healthcare if there were more ethical ways to share data?</p>
</li>
</ul>

<p>To kickstart my learning, I started with Introduction to Notebook Projects which seems like the basics.</p>
<ul>
<li>For this exercise, I learnt what a Notebook is and learnt how to troubleshoot on it as well. For someone that uses VS Code, It’s a bit funny but I appreciate the knowledge.</li>

<p>Welcome to day 3 of 100 days of Mida, where I look at software with new eyes and provide improvements or innovative solutions.</p>
<p>Today’s software application is YouTube.</p>
<p>As someone who loves to take social media detox and also embraces the arts on YouTube, I found myself setting alarms to take breaks to avoid getting sucked in during my spare time.</p>
<p>In a conversation with people who also loved watching videos but value their mental health.</p>
<p>I’ve found that we just want a sustainable way to consume media, and that brought up the idea of taking breaks (which is implemented on YouTube) from its hidden place on YouTube to a catchy front row seat 🍿</p>
