Summary#

Strong foundation in relational database concepts including schema design, query optimization, and integration with applications. Experience with multiple database systems and both direct SQL and ORM-based approaches to data management.

How I Apply This Skill#

• Designed normalized database schemas using EER diagrams before implementation
• Wrote complex SQL queries with joins, subqueries, and aggregations
• Implemented query optimization analyzing execution plans and indexing strategies
• Built application integrations using JDBC (Java) and raw SQL (Python)
• Worked with distributed databases implementing two-phase commit for consistency
• Applied SQL injection prevention using parameterized queries

Key Strengths#

• Schema Design: Normalization, EER diagrams, referential integrity
• Query Writing: Complex joins, subqueries, window functions
• Optimization: B+ tree indexing, execution plan analysis
• Multiple DBMS: SQL Server, MySQL, SQLite, PostgreSQL
• Security: Parameterized queries, SQL injection prevention
