Relational Database (DB) Visualized

Jude

Relational DB Designer is a free, single-file web app for learning how relational databases are designed and built. It runs in any browser with nothing to install and no sign-up, and works offline.

You design a database visually on a canvas. You create tables, rename them, add columns with data types, and drag tables around to arrange them. Primary keys are marked with a gold 🔑 badge and underlined names, and foreign keys with a blue 🔗 badge in italics. Each relationship is drawn as a line between tables using crow’s-foot notation and labelled one-to-one (1 : 1) or one-to-many (1 : N). A relationship wizard sets up one-to-one, one-to-many and many-to-many links for you, and builds the junction table that a many-to-many link needs.

Project HUSH - Prototype

Jude Perera

Project HUSH is a sound-driven zombie survival horror prototype developed in an isometric perspective as a preview.

Project HUSH is a sound-driven zombie survival horror prototype developed in an isometric perspective as a preview of a planned third-person game developed by me as a personal project. Set in a world devastated by a recent outbreak, the game focuses on stealth, resource management, and survival, where every sound can attract the infected—including terrifying creatures capable of mimicking human voices. The prototype explores the core gameplay mechanics and atmosphere, laying the foundation for a more immersive, story-driven survival experience.
