Ajoutez un champ `correlationId` unique dans chaque événement pour garantir l'idempotence : stockez les IDs traités dans une base clé-valeur, et ignorez les doublons. Pour le versionnage, adoptez un registre de schémas (Avro/Protobuf) avec compatibilité ascendante – cela évite de casser les consommateurs anciens.

DALL-E Prompt to Generate a Database Schema
DALL-E, OpenAI's image generation model, can be creatively used to produce visual database schemas. Whether you are a developer, software architect, or student, visualizing a database structure as an entity-relationship diagram is essential for understanding links between tables, primary keys, and relationships. Rather than using technical tools like dbdiagram.io or Lucidchart, DALL-E allows you to quickly generate a clear and aesthetic visual of a relational schema, ideal for presentations, educational documents, or brainstorming sessions. The main challenge lies in formulating the prompt: you need to guide the model precisely to obtain a readable diagram, with explicit table names, well-defined columns, and relationships clearly represented by lines and cardinalities. In this guide, you will discover an optimized prompt to generate a professional database schema with DALL-E, as well as variants adapted to your level of expertise and the complexity of your project.
