Obtaining SQLD Certification

Sun, 29 Sep 2024 00:00:00 +0000

I studied for the SQLD certification based on my skills in SQL and knowledge of data modeling.

GOAL

I aimed to pass the 54th SQLD exam, which will be held on August 24, 2024.

설명

SQLD is a nationally recognized certification administered by the Korea Data Agency. SQLD stands for SQL Developer, which refers to a developer who has the ability to directly access, manipulate, and develop databases using SQL. The exam assesses SQL skills based on knowledge of data modeling. There are no specific eligibility requirements, and the passing criteria for the exam are a total score of 60 points and at least 40% in each subject.

Overview

In the previous semester, I took a database course where I learned the basics of data modeling and how to use SQL. While considering how to apply what I had learned in the course for review, I discovered the SQLD certification and promptly registered for the exam and began studying. I supplemented my theoretical knowledge by purchasing a private theory book. Since the exam does not provide any previous exam questions, so I studied using practical question book, and reviews from previous candidates. After much effort, I finally completed the exam and passed with a high score of 90.

Conclusion

I believe that the certification may not significantly contribute to a development position, but it was a great opportunity to review databases and learn about the areas I was lacking. As I studied databases, I found the certification to be manageable in terms of difficulty, making it a satisfying experience overall.

Web practice using HTML, CSS, and JS

Wed, 25 Sep 2024 00:00:00 +0000

In August 2024, I created my own basic website using HTML, CSS, and JavaScript.

GOAL

The goal was to introduce a few series that I enjoyed watching, focusing on the theme of series. Additionally, I aimed to learn the basic syntax of HTML, CSS, and JavaScript, and to work with the components of the web by directly setting up text, icons, names, and more.

DESCRIPTION

I adopted the MPA (Multi-Page Application) approach so that when users perform specific interactions (such as clicking a button), they can navigate to designated pages and view the information they desire. To prevent the dullness of text-only content, I inserted images of each series and linked to official or reference sites so users can obtain additional information. I implemented a comment feature on the web page using. I implemented a comment feature on the web page using DISQUS and enabled direct communication between users and the developer (myself) using TAWK. Additionally, I deployed the project using GitHub Repositories, allowing anyone to access the web from anywhere.

CONCLUSION

The UI and content of the website are somewhat lacking, but it was very useful for learning WEB. Additionally, this experience provided me with more motivation to continue studying web development.

REFERENCE

This project was completed based on the materials from opentutorials.

2022-1 Club(WHO) Mentoring

Sun, 22 Sep 2024 00:00:00 +0000

As a mentor, I taught C language and basic algorithms to new students.

In addition, the role was to review and supplement the difficult parts from the lectures, helping to address the challenges faced by new students.

Using Riot API with WPF

Sun, 22 Sep 2024 00:00:00 +0000

In February 2022, I studied WPF and API in advance to prepare for the Windows programming lecture scheduled to take.

Goal

The goal was to use the Riot API to retrieve user information by ID, providing the information in JSON format.

Diffrences

A website that implements the feature is OP.GG. However, I used WPF to implement that feature. Therefore, you don't need any web browsers, and you can use it only with programs.

And there are no restrictions received from any web server like op.gg, refreshing was more free within the range supported by the API and faster.

Result

The implementation of UI is not perfect, but I successfully implemented information inquiry through ID.

YouTube Searching with specific country code

Sun, 22 Sep 2024 00:00:00 +0000

YouTube's search function uses the user's country code to search mainly for videos in the region. Therefore, even if you want to search for foreign videos, the user's national video is recommended first.

GOAL

The goal is to implement a feature that searches for user-inputted keywords in a specific language and recommends videos from a specific country.

APIs

First, I used the Papago API to translate the words or sentences entered by the user into the specified language(It's not currently supported). The language detection feature identifies the language entered by the user and translates it into the specified language.

Secondly, the YouTube API is utilized. The API is requested using the country code of the specified language and the translated text. The returned data is then presented as a list in the interface, including the video title, thumbnail, and video link.

Result

This allows users to search for videos from their desired country in the language of their choice, without being limited by their own country.
