Modern serverless lakehouse implementing HOOK methodology, Unified Star Schema (USS), and Analytical Data Storage System (ADSS) principles on Adventure Works. Features programmatic model generation, event-enhanced Puppini bridges, and temporal resolution across DAS/DAB/DAR layers.

Analysis of New York State Police Department Arrests dataset. Created Dimensional Model for the provided dataset. Using Alteryx and Talend, built ETL pipelines to process, clean the data and create dimensions and facts in the destination database. Further, visualized the necessary details of the database using Tableau and PowerBI.

This repository is a place for the Data Warehousing course at the Information Systems & Analytics department, Santa Clara University.

This project demonstrates an ETL pipeline that processes NOAA's fishing survey data, then makes it available for analysis through an interactive web app.

Dimensional Data Design

A Data Warehousing project for retail sales using dimension modelling best practices with SCD type 2 on AWS Redshift. Utilizing AWS Lambda, Glue Workflows and Python Shell jobs to create and automate an ELT pipeline where batch data coming into S3 is loaded onto Redshift and necessary transformations are performed to meet requirements.

Projeto end-to-end da criação de um Data Warehouse para uma companhia fictícia de mineração chamada Astarte Mining Co.

creating a data warehouse for a football game management company and some SQL queries to analyse data.

The project involves creating a data model for HNG Hire, implementing it in MySQL, and building a Power BI dashboard to display hiring statistics.

A comprehensive dimensional model for COVID data, enabling insights for future vaccination campaigns through robust visual analytics.

This project builds a cloud-based ETL pipeline for Sparkify to move data to a cloud data warehouse. It extracts song and user activity data from AWS S3, stages it in Redshift, and transforms it into a star-schema data model with fact and dimension tables, enabling efficient querying to answer business questions.

This project involves creating a dimensional data model using MySQL Workbench for a car repair shop’s operations in western Canada by examining a sample invoice,
