dbt enables data analysts and engineers to transform their data using the same practices that software engineers use to build applications.

Open-source BI for engineers

The best place to learn data engineering. Built and maintained by the data engineering community.

Few projects related to Data Engineering including Data Modeling, Infrastructure setup on cloud, Data Warehousing and Data Lake development.

MetricFlow allows you to define, build, and maintain metrics in code.

Build data pipelines with SQL and Python, ingest data from different sources, add quality checks, and build end-to-end flows.

Personal Data Engineering Projects

Data querying library for testing JavaScript applications.

do more with dbt. dbt-fal helps you run Python alongside dbt, so you can send Slack alerts, detect anomalies and build machine learning models.

ATTENTION: This repository is a clone of https://gitlab.structr.com/structr/structr. All development/issue tracking has moved there. | Structr is an integrated open-source low-code development and runtime environment that uses a graph database (Neo4j).

LLM-based ontological extraction tools, including SPIRES

:zap: A collection of resources and tutorials to design a better database schema.

Python library and web service for Open Source Software Health and Sustainability metrics & data collection. You can find our documentation and new contributor information easily here: https://oss-augur.readthedocs.io/en/main/

A developer experience centered on CUE. Unifies schemas, data models, deterministic and agentic code generation, workflow and task engine, dagger powered environments, coding assistant, and vscode extension; woven together on the CUE lattice. Squint harder if you can't see the cube :]

A hackable data integration & analysis tool to enable non technical users to edit data processing jobs and visualise data on demand.

Create diagrams and plan your code with TypeScript.

Sample databases for postgres

Linked Open Data Modeling Language

Repository for the ActivitySchema spec and supporting materials

Typed struct and value objects

Tellery lets you build metrics using SQL and bring them to your team. As easy as using a document. As powerful as a data modeling tool.

Type annotations for specifying, validating, and serializing arrays with arbitrary backends in Pydantic (and beyond)

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.

The goal of this project is to track the expenses of Uber Rides and Uber Eats through data Engineering processes using technologies such as Apache Airflow, AWS Redshift and Power BI.

Data processing and modelling framework for automating tasks (incl. Python & SQL transformations).
