rdt-ui-crud

rdt-ui-crud is a Streamlit in Snowflake application that provides a consumer-facing data entry form for creating, reading, updating, and deleting entity instances directly against Snowflake tables.

This application runs outside the CLI pipeline — it is deployed as a Streamlit app within Snowflake and consumes artifacts generated by the pipeline.

Directory: ui/crud/

How it works

The CRUD form reads a crud.json artifact (generated by the CLI pipeline) to dynamically render a data entry form tailored to the entity’s schema. The form enforces governance metadata (ownership, classification, PII flags) and writes directly to the entity’s Snowflake tables.

CLI pipeline generates crud.json → Streamlit app reads spec → Renders dynamic form → Writes to Snowflake

Input artifacts

Artifact	Source	Purpose
`models/{entity}/crud.json`	Generated by CLI pipeline	Form schema, field definitions, validation rules
`models/{entity}/governance.json`	`rdt-model-govern`	Ownership, stewardship, data classification, PII flags

Features

Dynamic form rendering from crud.json schema
Governance metadata display (owner, steward, classification)
PII data warnings
Create, read, update, and delete operations against Snowflake

Deployment

The app is deployed as a Streamlit in Snowflake application, meaning it runs natively within the Snowflake environment with session-based authentication — no external credentials required.

├── app.py                   # Streamlit entry point
├── requirements.txt         # Python dependencies
└── schemas/crud.schema.json # JSON contract for CRUD artifact

Status

Scaffold only — the UI shell and spec loading are implemented, but Snowflake session integration, actual CRUD operations, and ServiceNow workflow integration are pending.

rdt-ui-ratification — Steward approval UI (companion app)
rdt-model-store — Generates the Snowflake tables this app writes to
rdt-model-govern — Provides governance metadata displayed in the form
