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 ...

SQL Journey: Blog#10

So far, we are only "reading" from a given database or table using the SELECT command of SQL. In today's lesson, we will now start "writing" into a given database using the UPDATE and DELETE commands. Challenge: Dynamic Documents Given data: CREATE table documents (     id INTEGER PRIMARY KEY AUTOINCREMENT,     title TEXT,     content TEXT,     author TEXT);      INSERT INTO documents (author, title, content)     VALUES ("Puff T.M. Dragon", "Fancy Stuff", "Ceiling wax, dragon wings, etc."); INSERT INTO documents (author, title, content)     VALUES ("Puff T.M.
