Aster Express is a fully functioning Aster environment. It will allow you to build tables, load data into those tables, and run Aster specific analytics. Aster Express can be used by developer, testers, and anyone who is interested in learning more about Aster functionality. We only limit you by the size of data that you can load into the environment. (limited to 9gb to 17gb of data) It is not licensed for production use and runs on your Microsoft desktop on a couple of VMWare images.
