If you mean the default database in the modeler:
In the modeler, use menu option Team / Add snapshot of data and then commit. The other team member can apply the snapshot by updating from team server and deleting the deployment directory in the project directory. (Use menu option Project / Show project directory... to get there) After running locally again, the snapshot data will be loaded.
Several options : db backup/restore, import/export xml, excel export/import.
