Transfer objects of the MongoDB Plug-in allow data to be exchanged read and write with MongoDB. A separate transfer object is available for each activity (insert, select, update, delete).
Select, Update, Delete
For actions to select, manipulate or delete data, comfortable filters can be created in the transfer object itself. The filter fields are then available at the transfer object for filling in the connection. The queried data, as well as the data required for manipulation, are transferred via a “Data” field. The transfer normally takes place in JSON format, but can also take place in any other format.
With the Insert Transfer object, the data to be inserted is transferred via the “Data” field as JSON or in any format. The primary key of the data in the MongoDB, the object ID, can be specified, or determined by the database itself. If the ID is to be specified, a corresponding field appears on the transfer object at the input. If an automatic ID assignment is selected, a field for the assigned ID appears at the exit of the transfer object.
