DVC versions datasets and models via metadata files (.dvc) and a content-hash cache so Git stores only small pointers while actual data lives in remotes; example uses a Vokras image set and Titanic pipeline. Pipelines are declared in dvc.yaml with params.yaml for test_size and random_seed, stages run with dvc repro and experiments listed with dvc exp show, and data pushed with dvc push. Reruns skip unchanged stages, CI/CD can trigger full reproducible runs.
