Introduction to Spoon Perspectives
Spoon Perspectives are a set of functionality so distinct from other areas of Spoon that they've been designed to take over the whole look of the application. The traditional ETL functionality of Spoon is the default perspective and with the release of AGILE_BI_RELEASE_NUM, two additional perspectives have been introduced for Modeling and Visualization of data.
Adding a New Perspective to Spoon
Perspectives are supplied by Spoon Plugins (link to Spoon Plugin Doc). Each Spoon Plugin can provide only one perspective, though several Spoon plugins can be packaged together.
