+## TIL
+
+Today, my daily routine consisted of both physical training and academic coursework. For my physical conditioning, I completed a "push-day" resistance training regimen, which included exercises such as pullovers, dumbbell presses, pec deck flyes, overhead presses, side lateral raises, triceps extensions, and core workouts.  
+
+Academically, I focused on two subjects: "Fundamentals of Python Programming" and "Database Systems". While the introductory Python module was exceptionally straighforward for me, the database course, specifically the section of "Relational Models", presented a notable challenge. Although the fundamental concepts of relational models were relatively easy to comprehend, grasping the specific terminology and intricate details proved to be difficult.  
+
+Furthermore, translating an Entity-Relationship model into a logical data model requries significantly more analytical effort than simply executing SQL queries. In particular, relational algebra encompasses numerous operational concepts that are quite challenging to memorize. Consequently, from a practical standpoint, writing SQL queries is considerably more intuitive.
