SQL Server and MSDE Web Interface

ASP Enterprise Manager is a web-based interface for Microsoft SQL Server and MSDE written using ASP.Net, VB.Net and C#.Net. This project was developed to allow many SQL Server and MSDE design and administration tasks to be performed from any computer with a web browser.

Below are some screens that illustrate various tasks that can be performed using the ASP Enterprise Manager for SQL Server and MSDE. This project is under development and new tasks are constantly being added and current tasks enhanced. Wherever possible, we are trying to keep the familiar look and feel of Microsoft's SQL Server Enterprise manager.
