+# Step 3: Define Database Tables
+
+# Example: Define database tables using SQL

+# Step 4: Implement Schema in Database Management System (DBMS)
+# Example: Execute SQL statements to create tables in PostgreSQL
+
+# Step 5: Test Schema
+# Example: Populate database with sample data and perform tests to ensure functionality
+
+# Step 6: Integrate Schema into Software
+
+# Example: Connect to the database using an ORM like SQLAlchemy and define models
