Structured object data version processing method and device and electronic equipment

The invention discloses a version processing method and device for structured object data and electronic equipment. The method comprises the steps that a version data space for storing historical version data of structured object data is determined, and at least an object version snapshot table, an object index snapshot table and an engineering version information table are stored in the version data space; generating new version data of any structured object data and writing the new version data into the version data space; generating new version data of the whole project and writing the new version data into the version data space; determining original structure data of a historical version of the target object from the object version snapshot table; and determining an object index list of the target engineering version from the object index snapshot table and the engineering version information table. The technical problem that in the prior art, when version management is conducted on structured object dat
