SQL, Python, Tableau: The 'Power Trio' of Data Skills Helps Vietnamese Compete Globally

In the modern business world, data has become the new “currency”, and those who are fluent in its language are the most sought-after experts. With more than 20 years of experience working at large corporations in Europe, expert Tran Van Hoang Nam has climbed to the top of his career thanks to mastering a powerful set of tools: SQL, Python and Tableau. He considers this the “Power Trio” that helps turn dry numbers into strategic business decisions.

SQL, Python, Tableau: The 'power trio' of data skills helps Vietnamese people compete globally.

For a data professional, mastering all three of these tools is like being an architect who not only knows how to draw blueprints but also understands building materials and knows how to present ideas convincingly.

SQL - The Foundation of Everything

SQL (Structured Query Language) is a language for "talking" to data. It allows you to query, extract, and manage data from large databases. If data is a treasure, SQL is the key to unlocking that treasure.

In his profile, Nam highlighted his SQL (Advanced) skills. This shows that he is not only able to extract basic data, but also has the ability to handle complex queries, combining different data sets to find deeper relationships. This is the core foundation, because without SQL, data analysis would not be possible.

Python - The Analytical Brain

If SQL is the key, Python is the “brain” that helps you process and analyze the extracted information. With powerful libraries like Pandas and NumPy , Python allows data professionals to perform in-depth analysis, build statistical models, and find the stories behind the numbers.

Nam used Python (combined with Pandas and NumPy) to analyze user behavior, optimize business campaigns, and build algorithmic pricing models. Instead of just receiving ready-made reports, he used Python to dig deep, ask the right questions, and find answers based on data evidence. This was a breakthrough from a data worker to a data master.

Tableau - The Art of Storytelling

Data and analysis are only valuable when they are effectively communicated to decision makers. That's where Tableau comes in. Tableau is a data visualization tool that turns boring spreadsheets into beautiful, easy-to-understand charts and graphs.

Nam has used Tableau as a tool to “tell stories” with data. He believes that a visual chart can convey a message more powerfully than hundreds of lines of data. With Tableau, he can present complex analysis results in a simple way, helping managers quickly grasp the situation and make timely decisions.

Absolute competitive advantage

In the context of global integration, mastering all three of these skills will bring an absolute competitive advantage in the labor market. SQL helps you get data, Python helps you analyze data, and Tableau helps you present the analysis results. This is a complete cycle, helping data technologists not only become “workers” but also “artisans”, capable of mastering the entire process.

The story of expert Tran Van Hoang Nam is a clear example: from a person with a solid mathematical foundation, he has equipped himself with this “power trio” to become one of the leading leaders in the field of technology. This is a valuable lesson for young Vietnamese people who dream of reaching out to the world .
