You may want to edit data in the field, at the actual work site, and then update the central database with your changes when you return to the office. If you have a copy of AutoCAD Map 3D on a laptop computer, you can work “offline” in this way. The central database can be a relational database such as Oracle or Microsoft SQL Server, or it can be a file-based data store, such as SDF or SHP. The process works in exactly the same way for all data that you access using the FDO providers in the Data Connect dialog box.
To work offline, you first check out the features you want to work on. AutoCAD Map 3D makes a local copy of the features. You can then disconnect from your network and make your edits at the work site. Later, when you reconnect to the network with your edits, you can synchronize those changes with the central database.
