Udacity Data Engineering Nanodegree Program
[MOVED to Data Engine Thinking] A library for data warehouse and data integration pattern and architecture documentation.
Modeled for longitudinal storage and reporting of P-20W data, the Common Education Data Standards (CEDS) Data Warehouse implements star schema data warehouse normalization techniques for improved query performance.
The Common Education Data Standards (CEDS) Data Warehouse Parquet (DW Parquet) standard is designed for data engineering and data science needs in the cloud. The DW Parquet Models mirror the SQL-based CEDS Data Warehouse. Parquet files are designed for rapid and distributed reporting across multiple technology stacks, data processing and BI tool…
A blockchain enabled OLAP Data Warehouse. It is the implementation / application part of my thesis as an undergraduate Computer Science student of Athens University of Economics and Business
This is a repository to hold the files and notebooks produced throughout my Udacity's Nanodegree Data Engineering program.
Personal Projects submitted for the Data Engineer Nanodegree from Udacity.
End-to-end Enterprise Retail Analytics project using Python, Pandas, PostgreSQL, SQL, and Power BI.
Students will build an ETL pipeline that extracts data from S3, stages them in Redshift, and transforms data into a set of dimensional tables for their analytics team.
Production-ready ELT pipelines using Airflow
Oracle PL/SQL restaurant management system — normalized OLTP schema (reservations, orders, payments, inventory) with triggers/procedures, plus a star-schema data warehouse for sales and purchasing analytics.
