The Front-end Program is an application providing a friendly graphical user interface (GUI) with easy-to-use tools like buttons, forms, and tables and allowing users to access our back-end Oracle medical signal database via the Internet. The purpose of developing such an application is two-fold. First, the Front-end Program is a window for the Biomedical Signal Analysis Laboratory (BIOSAL) to share information with the society. By publishing across the Web, the research data we obtained in the laboratory can become valuable and utilizable for others. Second, on the internal side, the Front-End Program facilitates the lab employee, who is not necessarily familiar with the details of manipulating Oracle database. Thus the program provides three levels of access. The lab employee has the full accessibility to the whole database table space and the full object privileges. General public are allowed viewing only part of the database, the information we would like to share with them. WVU students in certain classes can have see more of our database than general public yet with lot of less privileges than those granted to the lab employee. We set up Developer 2000 as two-tiered (Figure 1) and Oracle Web Application Server (OWAS) as three-tiered configuration (Figure 2) in our development.
