Introduction to Data Engineering

Data engineering focuses on designing, building, and maintaining systems that enable the collection, storage, and analysis of data. It is a critical field that supports data-driven decision-making in organizations.

Key concepts in data engineering include:

  • ETL Pipelines: The process of extracting data from various sources, transforming it into a usable format, and loading it into a target system (e.g., a database or data warehouse).
  • Orchestration and Scheduling: Automating and managing workflows to ensure data pipelines run reliably and on schedule.
  • SFTP Integration: Securely transferring files between systems as part of the data pipeline.
  • Dashboards: Visualizing data insights using tools like Streamlit.

ETL Pipelines

ETL (Extract, Transform, Load) is a core process in data engineering. It involves:

  1. Extract: Retrieving data from various sources such as APIs, databases, or flat files.
  2. Transform: Cleaning, enriching, and converting the data into a usable format.
  3. Load: Storing the transformed data into a target system, such as a data warehouse or database.

This repository provides examples and resources for building ETL pipelines using modern tools and frameworks.


Orchestration and Scheduling

Orchestration and scheduling are essential for automating and managing data workflows. This repository includes examples of:

  • Workflow Orchestration: Using tools like Apache Airflow or Prefect to manage complex ETL pipelines.
  • Scheduling: Automating pipeline execution using cron jobs or orchestration tools.
  • Error Handling: Ensuring workflows are robust and can recover from failures.

Sections and Resources

1. Data Extraction

This section covers techniques and tools for extracting data from various sources, including:

  • APIs
  • Relational databases
  • Flat files (e.g., CSV, JSON)

2. Data Transformation

Learn how to clean, enrich, and transform raw data into a structured format. Topics include:

  • Data cleaning with Python (e.g., Pandas)
  • Data validation techniques

3. Data Loading

Explore methods for loading transformed data into target systems, such as:

  • Relational databases (e.g., PostgreSQL, MySQL)
  • Data warehouses (e.g., Snowflake, BigQuery)
  • Cloud storage (e.g., AWS S3, Azure Blob Storage)

4. SFTP Integration

This section demonstrates how to securely transfer files between systems using SFTP. Topics include:

5. ETL Pipeline Orchestrator

Learn how to orchestrate and schedule ETL pipelines using different tools. Topics include:

6. Streamlit Dashboard

Build interactive dashboards to visualize data insights. Topics include:
