Project Items¶
Project items in the Design view and the connections between them make up the graph (Directed Acyclic Graph, DAG) that is executed when the or buttons are pressed.
See Executing Projects for more information on how the DAG is processed by Spine Toolbox.
The following items are currently available:
Data Store ¶
A Data store item represents a connection to a Spine model database. Currently, the item supports sqlite and mysql dialects. The database can be accessed and modified using data store views available from the item’s properties or from a right-click context menu.
Data Connection ¶
A Data connection item provides access to data files. It also provides access to the Datapackage editor.
Tool ¶
Tool is the heart of a DAG. It is usually the actual model to be executed in Spine Toolbox but can be an arbitrary script or executable as well. A tool is specified by its template.
View ¶
A View item is meant for inspecting data from multiple sources using the data store views. Note that the data is opened in read-only mode so modifications are not possible from the View item.
Note
Currently, only Tree view supports multiple databases.
Data Interface ¶
This item provides mapping from tabulated data (comma separated values, Excel) to the Spine data model.
