SQL Journey: Blog #15

I am now on SQL Advanced queries and the lesson focused on temp tables. As the name suggests, temp tables allow us to create tables outside of the database which is stored somewhere in memory.

What I find interesting about this lesson is the fact that we can extract a table from our database and store it on our temp table for FASTER data manipulation and analysis LOCALLY. I could imagine a scenario wherein I am working from home and I am told to work on a specific table on the database that is situated miles away but can be accessed using the internet. Now, instead of wasting internet resources every time I get data and execute SQL queries to and from the database, I can now extract the tables I need from the database, work on it it locally and then be able to report the needed insights and visualizations.

Gears Update

It has been a while since my last post and many things have happened since then. For one, I decided to upgrade my laptop as I saw it fit for the direction I am moving towards particularly on data analytics. It's been almost 10 years since I bought "Julian", my first work laptop, and there were so many milestones that we shared together. I bought my first laptop during my second job in Taguig City. It served as an extension of myself as I work to earn for my family particularly in helping my siblings with their education as I am the eldest and breadwinner of the family. That laptop was able to create a joint personnel reporting system excel file which was used by the Philippine Army to be able to account their personnel on a national level during my stint as an Engineer / Researcher in the aforementioned organization. Julian was my laptop when I finished my Master's degree at the Ateneo de Davao University where I also created the Programmable Logic Controller Trainer ...

Coursehero: The Comments that I received from Students all over the world (2022)

What's up Nixers! I was inspired to do a blog today since I was supposed to watch some netflix videos but figured why not pass by here for a while. I recently visited my account and found that my latest answer was tagged as helpful by the student with a custom-made message with a heart. For those of you who do not know, there are three things that you get to receive from students when answering questions in Coursehero. (1) Unhelpful which means your answer may either be incorrect, was no longer needed by the student (since the submission of the assignment has already lapsed and you were too late to answer the question) or they just don't feel connected to your solution. You see, in this platform, you really cannot please everybody. I find it a hard and bitter pill to swallow. After all, I did my part. I dedicated brain cells to answer the question and yet, it was unhelpful? Worst of all, I won't get paid for that time I spent answering the question. But yeah, one thing tha...
