Users will see a common user interface, common architecture, and a single development environment. ArcView is available as a single-use or concurrent license. Regardless of the license type, the functionality of ArcView is identical. ArcGIS extensions are also licensed as either single use or concurrent. Concurrent extensions operate with ArcInfo, ArcEditor, and the concurrent version of ArcView.
Users can upgrade to either single-use or concurrent licenses.
The concurrent license, however, has two distinct advantages. First, it can float or be shared across the network. Second, it can share concurrent extensions. The ArcView 3.2a release is a free downloadable upgrade for existing ArcView 3.2 users. ArcView 8.1 is in prerelease and is scheduled to be available in Spring 2001 for Windows NT and Windows 2000.
