RDBMS Using Postgresql

1. The RDBMS Foundation (The "Why")

Before diving into code, students must understand how data relates.

• ACID Properties: Atomic, Consistent, Isolated, Durable—the gold standard of RDBMS.

• Normalization: Teaching how to design schemas that prevent data anomalies.

• ER Modeling: Using tools like pgAdmin or Lucidchart to map out entity relationships.

2. Core PostgreSQL Development

• SQL Mastery: Moving from basic SELECT to complex JOINs, CTEs (Common Table Expressions), and subqueries.

• Data Integrity: Implementing CHECK constraints, FOREIGN KEYS, and UNIQUE indexes.

• Advanced Types: Teaching PostgreSQL’s unique strengths like JSONB, Arrays, and Geometric types.

3. PostgreSQL DBA & Performance (For Professionals)

This is where you can charge a premium on UrbanPro.

• Indexing: Explaining B-Tree, GIN (for search), and GiST indexes.

• Query Optimization: Using EXPLAIN ANALYZE to identify and fix slow queries.

• MVCC: Explaining Multi-Version Concurrency Control—how Postgres handles multiple users without locking the whole table.

This forms the basis of students who later want to become data analyst, data engineer , backend developers.
Playing with data and able to retrieve data from database by writting optimized queries is a blessing.
