+
+## Overview
+
+This document provides basic guidance for updating your application to work with the migrated PostgreSQL database.
+
+## Migration Summary
+
+- **Total Objects**: 3
+- **Conversion Rate**: Unknown%
+- **Total Chunks**: 3
+- **Completed Chunks**: 3
+
+## Migration Notes
+
+### Schema_Structure_Changes
+**Impact**: medium
+**Summary**: Oracle schemas are implicit and tied to users, while PostgreSQL requires explicit schema creation.
+**Affected Objects**: PHOTOALBUM
+The migration involved converting the implicit Oracle schema to an explicit PostgreSQL schema using CREATE SCHEMA IF NOT EXISTS.
+
+### Table_Conversion
+**Impact**: high
+**Summary**: Oracle NUMBER(19,0) and NUMBER(10,0) columns converted to PostgreSQL BIGINT for file_size, height, and width. Oracle BLOB column PHOTO_DATA converted to PostgreSQL BYTEA. Oracle TIMESTAMP(6) DEFAULT SYSTIMESTAMP converted to PostgreSQL TIMESTAMP DEFAULT CURRENT_TIMESTAMP. Oracle tablespace, storage, and LOB options omitted as they are not applicable in PostgreSQL.
+**Affected Objects**: PHOTOALBUM.PHOTOS
+Column type conversions: NUMBER(19,0) and NUMBER(10,0) → BIGINT; BLOB → BYTEA; TIMESTAMP(6) DEFAULT SYSTIMESTAMP → TIMESTAMP DEFAULT CURRENT_TIMESTAMP. Oracle tablespace, storage, and LOB options omitted as not applicable in PostgreSQL.
+
+### Index_Handling
+**Impact**: medium
+**Summary**: Oracle quoted UPPERCASE identifiers for schema, table, index, and column were converted to PostgreSQL lowercase unquoted names for schema/table/index, but the column name was quoted as "uploaded_at" to preserve case sensitivity and avoid naming errors.
+**Affected Objects**: PHOTOALBUM.IDX_PHOTOS_UPLOADED_AT
+Identifier conversion: schema/table/index names lowercased and unquoted; column name "uploaded_at" quoted to preserve case sensitivity and avoid naming errors.

+# Application Migration Coding Notes
+
+**Migration Project**: localhost  
+**Generated**: 2025-11-10 16:43:46
+
+This document provides guidance for updating application code 
+after the Oracle → PostgreSQL database migration.
+
+## Summary
+
+- **Total coding notes**: 2
+- **Critical impact**: 0
+- **High impact**: 0
+- **Medium impact**: 1
+- **Low impact**: 1
+
+## Medium Impact Changes
+
+### cn_001: Oracle NUMBER types converted to PostgreSQL equivalents
+
+**Object**: All numeric columns  
+**Category**: data_type_changes  
+**Impact**: medium
+
+**Pattern Change**:
+- Oracle: `NUMBER(precision, scale)`
+- PostgreSQL: `BIGINT, DECIMAL, or NUMERIC`
+
+**Application Changes Required**:
+- Review entity classes for data type compatibility
+- Update API documentation with new data types
+- Verify that existing data fits in new type ranges
+
+**Code Examples**:
+
+*Java_Entity*:
+```
+// Before
+@Column(name = "amount")
+private Integer amount;
+
+// After
+@Column(name = "amount")
+private Long amount;
+```
+
+---
+
+## Low Impact Changes
+
+### cn_002: Oracle sequence syntax converted to PostgreSQL SERIAL or IDENTITY
+
+**Object**: Sequence usage  
+**Category**: sql_syntax_changes  
+**Impact**: low
+
+**Pattern Change**:
+- Oracle: `sequence_name.NEXTVAL`
+- PostgreSQL: `SERIAL or IDENTITY columns`
+
+**Application Changes Required**:
+- Remove explicit sequence calls in INSERT statements
+- Update ORM mappings for auto-generated IDs
+- Verify ID generation in application tests
+
+**Code Examples**:
+
+*Sql*:
+```
+// Before
+INSERT INTO employees (id, name) VALUES (emp_seq.NEXTVAL, 'John')
+
+// After
+INSERT INTO employees (name) VALUES ('John') -- ID auto-generated
+```
+
+---
+
+## Development Checklist
+
+### Database Schema Updates
+- [ ] Update ORM entity classes with new data types
+- [ ] Verify foreign key relationships work correctly
+- [ ] Test sequence/identity column behavior
+- [ ] Update database migration scripts
+
+### Application Code Updates
+- [ ] Review and update SQL queries for PostgreSQL syntax
+- [ ] Update data access layer for new data types
+- [ ] Verify error handling for PostgreSQL error codes
+- [ ] Update connection strings and database configuration
+
+### Testing
+- [ ] Run full application test suite
+- [ ] Verify data integrity after migration
+- [ ] Test performance with PostgreSQL
+- [ ] Validate all application features work correctly
+
+### Deployment
+- [ ] Update CI/CD pipeline for PostgreSQL
+- [ ] Update application configuration
+- [ ] Plan rollback strategy if needed
+- [ ] Monitor application after deployment
