O2oa

o2oa is an open-source Java enterprise office automation platform designed to manage corporate workflows, organizational hierarchies, and collaborative office tasks. It functions as a low-code business application platform and a corporate information portal, providing a visual development environment for building custom enterprise applications.

The platform is distinguished by its integrated enterprise workflow engine, which allows for the design and automation of business processes using customizable routing conditions and event-driven scripts. It further differentiates itself as a multi-database enterprise framework, supporting various relational databases and high-availability deployments across different operating systems.

The system covers a broad range of capability areas, including low-code visual modeling for forms and pages, centralized portal design with data-driven dashboards, and enterprise data integration with RESTful services and large language models. It also incorporates organizational structure management, role-based access control, and multi-platform mobile deployment for Android, iOS, and HarmonyOS.

Installation is supported across Linux and Windows environments using Docker and Nginx.
