Introduction to Editing Versioned Geodatabases: Concepts and Applications

This session provides an overview of editing versioned geodatabases, focusing on multi-user technology, versioning workflows, and types of editing. Designed for individuals with basic knowledge of relational databases and geodatabase data models, the session will cover essential topics such as archiving, geodatabase replication, and the management approach for multi-user environments. Attendees will learn the advantages of versioning, including independent edits and support for long transactions, and will participate in a Q&A session to address specific questions.
