You can import the layers into an XMap 5.0 or later-compatible database using the
Import Wizard in the GIS Workspace subtab or the New/Duplicate Layer feature in
the GIS tab. Advanced users can convert multiple files using the XMap GIS Bulk
Importer/Exporter.
XMap 5.x Database Limitations
Layers created in XMap 5.x do not support self-intersecting polygons.
Backing Up a Database
This Help topic describes features that are available in XMap
Professional, XMap GIS Editor, and XMap GIS Enterprise.
Use the Backup/Restore feature in Database Manager to create backups (duplicates)
of databases in case of a computer crash or database corruption. You can restore the
backups if such an event occurs, preserving the user’s layers in the database. You
can create multiple backup databases for a single source database.
In case of computer failure, it is strongly recommended that you store database
backups on separate media (CD, DVD, remote server, etc.).
