RDOs

RDOs is an acronym that can refer to more than one concept in computing. Two widely encountered meanings are Remote Data Objects, a legacy data-access technology, and the OpenStack RDO distribution, a community-supported packaging of OpenStack for Red Hat–based Linux.

Remote Data Objects (RDO) were designed to provide a programming interface for interacting with relational databases via ODBC. The RDO object model typically included components for managing connections, executing commands, and handling result sets on remote data sources. It was used in several Windows development environments, including some versions of Visual Basic and Visual FoxPro. Over time, RDO was superseded by newer data-access technologies such as ADO and DAO, leading to a decline in its usage as developers migrated to more modern APIs.

RDO (OpenStack distribution) is a community-supported distribution of OpenStack that runs on CentOS, Fedora, and Red Hat Enterprise Linux. It provides packaged OpenStack components, alignment with upstream OpenStack releases, and deployment tooling to help users install and experiment with OpenStack in development and testing environments. The project is maintained by the community, with involvement from multiple contributors, and serves as a practical way to prototype OpenStack without relying on vendor-specific installers.

Context is important for interpreting the term RDOs, since the acronym can refer to different technologies in different domains. When in doubt, the intended meaning should be inferred from the surrounding technical context.
