QGIS or Spatialite : data loader ? (like ArcGIS)

Is there a tool that works like the data loader of ArcGIS for QGIS (or via Spatialite )? To integrate data in a database or a shapefile without having the same structure (and the tool allows to propose which column goes with every other column)

EDIT : example : We have a layer of trees; two people go on the field and inform each new tree layer (without necessarily having the same structure / field names). They come back ; I want to integrate their new trees quickly and easily without having to explicitly rename their fields: ArcGIS allows in a geodatabase with the tool "load data" that makes a direct link between the fields of the two layers (linking with a gui).
