Nahlédněte za oponu VersionPressu
VersionPress is an open-source version control plugin for WordPress that allows tracking of all changes made to a website. It assigns unique IDs to database entities to avoid conflicts when merging data between environments. It also handles foreign keys by defining relationships between database tables and values. The document discusses challenges with WordPress database design and how VersionPress addresses these through its own format for storing database data as files that can be version controlled.
