The Data Exchanger is a tool used to exchange data between data sources. It is viewed as a generic exporter. For each dataset it is possible to choose which attributes to export. It is also possible to change the attribute type if the default conversion is not supported by the the datasources involved.
It is accessible through ADMINISTRATION → DATASOURCE EXCHANGER.
Follow the wizard interface pressing Next button after each step.
Select the data source where the data is stored.
The Data Source Selector is used to choose an available data source and make its content visible as datasets to be selected.
Click on a Data Source type (PostGIS, Microsoft Access, Vector File or Raster Files).
Choose one of the Available Data Sources by clicking over it. If the list is empty click on to add one.
Click on Select and a new interface will be provided with all datasets available to be selected.
It is important to note that the datasets still at the original data source. Also you can combine datasets from different sources, for example you can select a shape file from a directory and a spatial table stored in a PostGIS database and draw them without any import/export action over the original data.
Besides that, the Data Source Selector is also used to define a way to connect with different data sources from where to search for data. Each type of Data Source has a specific set of parameters and for each of them there is an appropriate interface defined.
To add, remove, create a empty one, or update the connection parameters follow the steps bellow:
Click on
to add an existing data source as an Available Data Source and fill
the connections parameters.
Click on change icon
to change the connection parameters.
Click on data source
icon
to create a new empty data source.
Click on remove icon
to remove the connection reference from the list.
Select the datasets you want to transfer to another data source.
Select the target data source.
Transfer Options step
On Selected datasets frame there is a list of datasets to be exported. For each dataset selected you can change or provide more information on how the datasets will be transferred and mapped to the target data source.
On Properties frame the Status column of each property shows if the default conversion is supported between the data sources involved.
On the Constraints/Indexes frame it is possible to add constraints and indexes to the new dataset. The existing ones are listed and can be removed.
Name, Title and SRID (changing this will not cause data reprojection).
After all click on Commit to export the dataset to the target data source.
Check the Data exchange summary that will report the success or failure of the whole process.
