Which type of geodatabase allows multi-user editing without size limitations?

The Enterprise geodatabase is specifically designed to support multi-user editing and can handle large datasets effectively, making it ideal for environments where multiple users need to access and edit geographic information simultaneously. It operates on a relational database management system (RDBMS), facilitating the management of large volumes of spatial data and enabling concurrent access without the size limitations that may affect other types of geodatabases. This architecture allows for robust data integrity and security while also supporting advanced features, such as versioning, replication, and long transactions, which are essential in collaborative and dynamic GIS environments.

In contrast, personal geodatabases and file geodatabases are more suited for single-user scenarios or smaller teams. Personal geodatabases use Microsoft Access as a backend and have a file size limit of 2 GB, while file geodatabases, while larger than personal ones, can still be limited in concurrent access capabilities and are generally intended for smaller teams or individual users. Cloud geodatabases involve different architectures and operational constraints that may not align with traditional multi-user editing scenarios.
