Schema Documentation¶

This directory contains database schema definitions, data models, and field mappings for the Odoo migration project. These specifications ensure consistent data structures and proper relationships across all migrated systems.

🗄️ Schema Components¶

📋 Odoo Model Definitions¶

Core Odoo models and their relationships
Custom field definitions and extensions
Model inheritance and customization patterns

🔗 Field Mappings¶

Mapping between source system fields and Odoo fields
Data type conversion rules and validations
Required vs optional field specifications

🔄 Data Type Conversions¶

Rules for converting data types between systems
Validation and transformation logic
Error handling for data type mismatches

📊 Relationship Diagrams¶

Visual representations of data relationships
Foreign key mappings and constraints
Many-to-many relationship handling

✅ Validation Rules¶

Business rules and constraints for data integrity
Field validation and business logic
Data quality requirements

🔑 Key Models¶

Core Business Models¶

res.partner - Contacts and companies
product.template / product.product - Products and variants
sale.order / sale.order.line - Sales orders
account.payment.term - Payment terms
mrp.bom / mrp.bom.line - Bills of materials

Supporting Models¶

res.company - Multi-company setup
res.users - User management
account.account - Chart of accounts
stock.warehouse - Warehouse management

🚀 Migration Considerations¶

Data Integrity¶

Maintain referential integrity during migration
Handle orphaned records and broken relationships
Validate data consistency across models

Performance Optimization¶

Optimize field mappings for bulk operations
Consider indexing strategies for large datasets
Plan for incremental migration of large tables

Customization Impact¶

Document any custom fields or models
Plan for upgrade compatibility
Maintain customization documentation

Overview - Technical specifications and architecture
Functional Areas - Business domain models
Migration Scripts - Data import automation
Sample Data - Template and example data
Product Migration Strategy - Product schema details
Company Setup Policy - Multi-company schema

📋 Schema Documentation Standards¶

Model Documentation¶

Complete field definitions with types and constraints
Relationship mappings and cardinality
Business rules and validation logic
Customization points and extensions

Migration Mapping¶

Source-to-target field mappings
Data transformation rules
Default values and fallbacks
Error handling procedures

Version Control¶

Track schema changes over time
Document migration impact of changes
Maintain backward compatibility
Plan for future upgrades

🎯 Best Practices¶

Documentation First - Define schema before implementation
Validation - Test all field mappings and relationships
Consistency - Use consistent naming and structure patterns
Flexibility - Design for future changes and extensions
Performance - Consider query performance and indexing needs
