An application is usually used by several users where each user has access rights to certain forms in accordance with their authority or position. For example, the Inventory application or inventory is used by the Manager to view reports, the Warehouse section to check the stock of goods and the cashier to make purchases and sales transactions. Another example is the Academic Value application used by the Administration to input student and course data, Lecturers to input academic value data and Students to view academic value data. Access rights to use certain forms can be set directly in the program code with the consequence that if there is a change in access rights by certain users, you must change the program code, this is not a problem if the company can still contact the programmer to change the program code according to changes in user access rights but it will be a problem if the program maker cannot be contacted by the company to change the program code according to changes in user access rights.

Diskless server is a cluster computer network which uses SSH (Secure Shell) protocol to grant the client an access to the host's directory and modify it's content so that the client don't need a hardisk (Thin Client). One way to design a diskless server is by utilizing "Linux Terminal Server Project", an open source-based script for Linux. However, using Linux has it own drawback, such as it can't cross platform for running an aplication based on Windows system which are commonly used. This drawback can be overcomed by using a compatibility layer that converts a windows-based application's source code. The data which will be monitored is the compatibility layer implementation's result, and the throughput, packet loss, delay, and jitter. The result of measurement from those four parameters resulting in "Excellent" for throughput, "Perfect" for packet loss and delay, and "Good" for jitter.
