Object-relational mapper

Q: How deeply does AI-Powered Developer: Build software with ChatGPT and Copilot cover object-relational mapper?

Defines table, column, primary-key, foreign-key, and model-method mappings, but does not show complete persistence operations.

As explained in AI-Powered Developer: Build software with ChatGPT and Copilot

Object-relational mapping is a technique that represents relational database records as objects and translates between object operations and database operations.

An object-relational mapper represents database tables as application classes, connecting object attributes to columns and relationships to keys. An asset-management schema becomes Python model classes for funding details and assets, including a foreign-key link between them. section 5.1

Asset and funding models

FundingDetailsModel maps to funding_details and stores depreciation data. AssetModel maps to assets and includes asset details plus funding_details_id, which references funding_details.id.
