What is the difference between the Portal and the ER/Studio Viewer?
ER/Studio Viewer and the Portal can be used together with each providing different and unique benefits. ER/Studio Viewer provides advanced browsing and zooming of the data models, but without the ability to edit. The Viewer is perfect if you need a view-only look at your data models with advanced layout and print capabilities. The Portal uses powerful search and business intelligence technology to report on metadata across all of your data models in a single query. Because the Portal is accessible through an online browser, you can literally share the data with hundreds of users simultaneously.
