The first time I heard about ONNX was during my internship at INRIA. I was working to develop Neural Network Pruning algorithms in the Julia language. There weren't many pre-trained models yet that I could use, so utilizing ONNX to import models developed with other languages and frameworks might have been a solution. In this article, I want to introduce ONNX and explain its enormous potential by also seeing a practical example. ONNX, or Open Neural Network Exchange, is an open-source standard for representing deep learning models. It was developed by Facebook and Microsoft in order to make it easier for researchers and engineers to move models between different deep-learning frameworks and hardware platforms.

How we store and manage data has completely changed over the last decade. We moved from an ETL world to an ELT world, with companies like Fivetran pushing the trend. However, we don't think it is going to stop there; ELT is a transition in our mind towards EL(T) (with EL decoupled from T). And to understand this, we need to discern the underlying reasons for this trend, as they might show what's in store for the future. This is what we will be doing in this article. Historically, the data pipeline process consisted of extracting, transforming, and loading data into a warehouse or a data lake.
