Microsoft Fabric ETL for Azure Data Factory professionals
Usually everyone says Microsoft Fabric incorporates Data Factory ETL development resources. However, it's not so simple. Some concepts from Data Factory are not the same in Microsoft Fabric.
Let's discover the differences of the Pipelines and Dataflows in Fabric from the Azure Data Factory objects
Chat with your data using OpenAPI
AI is not the future anymore, it is the present. One challenging everyone is trying to solve is how to link your custom data with the powerful LLM models provided by OpenAI.
On this training day you will discover how to do that, either with modelled data and with unstructured data and documents.
We will talk about not only how to make the connection between OpenAI and your data, but also how to create UIs to access this environment, allowing the end user to talk with your data.
