OHDSI software turns shared data standards and methodological practices into a transparent, reproducible workflow. Researchers can design a study in ATLAS, coordinate its execution with Strategus, run analyses through HADES, and use diagnostic and results tools to evaluate and communicate the findings. Because the software is open source, study logic can be inspected, reused, and improved by the community.
You do not need to learn every OHDSI tool or repository. Begin with the task you need to complete: design a study, coordinate execution, run an analysis, or evaluate results. The documentation and tutorials will guide you to the relevant tools, while the forums and workgroups provide help when implementation questions arise.
