Projet Langages du Web L2 info

Ce projet a été fait dans le cadre de l'UE : Introduction aux Bases de Données encadrée par le professeur Shaoyi YIN. L’objectif est de ce projet est de concevoir une base de données complète à partir d’un scénario décrivant les besoins d’une compagnie d’assurances. Le projet suit une démarche progressive allant de l’analyse du besoin jusqu’à la modélisation relationnelle finale sur Oracle et la création de requêtes SQL.

Ayant beaucoup d'appétence pour le cinéma, les tables ont été créées en utilisant l’univers Marvel comme source d’inspiration.

Arrow & Parquet is a high-performance, fully client-side data transformation and analysis tool designed to bridge familiar data formats with modern, high-speed querying engines directly in the browser. It allows users to import Arrow, Arrows, CSV, and JSON files, instantly converting them into the highly optimized Parquet format using Rust WebAssembly. Native Parquet files can also be imported directly.

Once the data is securely loaded, an embedded DuckDB WASM engine enables users to perform complex SQL queries, validate data structures, and aggregate large datasets with zero server latency. After filtering and shaping the data, the final output can be exported as either CSV or Parquet files for seamless integration into downstream machine learning workflows or BI tools.

To handle robust data operations and large WebAssembly payloads without hitting strict hosting limits, the application is deployed via GitLab Pages and utilizes the browser's Origin Private File System (OPFS). This guarantees high-speed local storage and ensures that all data processing remains strictly local, providing absolute data privacy without ever transmitting sensitive information to an external server.

Built with Astro, Rust WebAssembly, and DuckDB WASM.
