Abstract

In the era of globalization and technological advancement, the need for fast, accurate, and easily accessible information has significantly increased. The CountryInfo App was developed as an innovative solution to simplify access to real-time country information. This application offers two main features: searching for country details by name and a randomizer feature for exploring country data interactively. Utilizing technologies such as Kotlin for user interface development, Flask for backend management, and public APIs for retrieving real-time data in JSON format, the application is designed to provide users with an intuitive and interactive experience. Testing results demonstrate a responsive performance, with an average access time of less than 2 seconds. This study aims to provide practical benefits to society in education, research, and personal needs while serving as a case study for API technology implementation in mobile application development.

Abstract

Online food ordering systems have become an important component of digital commerce because users increasingly expect fast, convenient, and reliable transaction processes. However, system development should not focus only on functional ordering features; it should also consider usability, transaction security, and the ability to transform transaction records into information for future analytical use. This study aims to design and develop a web-based Online Food Ordering Application using the Software Development Life Cycle (SDLC) Waterfall approach. User and seller requirements are translated into major functions including registration and authentication, food and beverage browsing, shopping cart management, checkout, payment, order history, product management, and order confirmation. A conceptual framework is introduced to explain the relationships among user needs, system design, usability, security, transaction efficiency, and the analytical utilization of transaction data. The application was implemented using PHP with HTML and CSS for the interface and a database for operational records. Functional validation was conducted using black-box testing on the documented login, menu, and payment scenarios. All documented scenarios produced the expected outputs and were categorized as passed. The results show that the prototype supports the basic food ordering workflow. Nevertheless, the present evaluation is limited to functional testing and does not yet provide quantitative usability measurements, comprehensive security testing, transaction-time benchmarking, or experimental evaluation of recommender and Business Intelligence modules. The stored transaction and order-history data are therefore positioned as a foundation for future behavioral analytics, Business Intelligence dashboards, and personalized food recommendation development.
