This organization contains projects focused on relational database design, SQL engineering, and data processing systems. The goal is to build a deep understanding of how data is modeled, stored, queried, and transformed efficiently in production backend systems.

Each repository focuses on a specific layer of database engineering rather than combining everything into a single system, allowing for deeper exploration of core concepts like transactions, indexing, query planning, and data pipelines.

This organization exists to:

• Develop strong SQL and relational database fundamentals
• Understand how data is modeled for real-world systems
• Explore performance tuning and query optimization
• Learn transactional consistency and isolation concepts
• Build data processing and ETL pipeline intuition
• Understand how PostgreSQL and relational systems work internally

Explores how data is extracted, transformed, and loaded into structured systems. Focuses on batch processing, data movement, and transformation logic.

Focuses on designing relational schemas, normalization, denormalization, and modeling tradeoffs for real-world applications.

Explores database transaction concepts including ACID properties, isolation levels, concurrency control, and failure recovery.

A focused exploration of PostgreSQL internals, including indexing, query planning, execution strategies, and performance behavior.

Focuses on improving SQL performance through indexing strategies, query restructuring, execution plan analysis, and performance tradeoffs.

Projects in this organization emphasize:

• Data consistency and correctness
• Efficient query design
• Schema design tradeoffs
• Performance-aware engineering
• Understanding database internals
• Practical application of relational theory

This is an active database engineering learning space. Each repository is developed independently to build deep understanding of relational systems and data engineering principles.
