The purpose of the Pentaho Design Studio is to facilitate the creation and management of files within your Pentaho solutions.  The Design Studio helps organize these files and provides editors for each type of file.  There are several levels of organization within the Design Studio: workspaces, project, views, editors, and perspectives. If you haven't done so already start up the design studio and take a look at the basic layout.

 

Workspaces

A workspace is a directory that contains a collection of projects, along with preferences and other settings related to the projects it contains.  When working in the Design Studio keep in mind you are working with a single workspace. If you would like to change the workspace currently being used by the Design Studio simply select the Set Workspace option from the File menu. The Design Studio comes with a preexisting workspace containing a single project called Default Project.

Projects, Folders and Files

There are three different types of resources in the Design Studio: projects, folders, and files. Projects are the largest structural unit used by the Design Studio. Projects contain folders and files, and they can be opened, closed, or built. Folders can contain other folders and files. The Design Studio provides a number of mechanisms for working with projects, folders and files.  A Pentaho BI solution is typically represented as a project of the Design Studio.  The folders and file represent the hierarchy of content within solutions. As mentioned earlier, the design studio comes preconfigured with a workspace that contains a single project name "Default Project". If you expand the project in the left hand tree you'll notice that the project contains a single file named "untitled.xaction".

Views

A view is a visual component within the Design Studio. It is typically used to navigate a hierarchy of information (such as the resources in the Design Studio), open an editor, or display properties for the active editor. Modifications made in a view are saved immediately. Normally, only one instance of a particular type of view may exist within a Design Studio window.  The "Package Explorer" displayed in the left hand side of the Design Studio is an example of a view.  The Package Explorer view displays the projects within the active workspace, and allows you to navigate the folders and files located within each project.

Editors

An editor is also a visual component within the Design Studio. It is typically used to edit or browse a resource. Modifications made in an editor follow an open-save-close lifecycle model. Multiple instances of an editor type may exist within a Design Studio window.  The Action Sequence Editor is one example of an editor. To see the Action Sequence Editor in action expand the "Default Project" in the Package Explorer view and double-click on untitled.xaction. The action sequence editor should appear.

Perspectives

A perspective is a group of views and editors in the Design Studio window. One or more perspectives can exist in a single Design Studio window. Each perspective contains one or more views and editors. Within a window, each perspective may have a different set of views but all perspectives share the same set of editors.  You can think of a perspective is a visual organization of the windows within a workspace. The default Design Studio configuration contains a single Perspective name "Pentaho". Note that the active perspective is displayed in the upper right hand corner of the Design Studio. The Pentaho perspective is a very simple perspective containing the Package Explorer view and an area reserved for the editor.
