| Abstract [eng] |
Each IS has features that are available only to users witch has the access right to them. In order to achieve this it is necessary access rights to the user and to filter each request to the server at the time. This has to be done very fast, because at the very huge amount of requests at the same time, filtering can take longer than the specified minimum response time in IS specification. This is especially true in today's IS, as they are increasingly used an interactive user interface, which imposes a dynamic data, but also increases the number of queries to the server. The aim is to explore the parameters (users, rights groups and the number of features) on the system of user rights management method for speed and propose a method to exhibit performance and requires a large amount of RAM. This is achieved by the selected Lithuanian University of Health Sciences education information system, which is realized in the proposed rights management method. In order to prove the superiority of the proposed method and to investigate the influence of the parameters of the method performance has been realized the simulator, witch simulate a real load of IS and measure response time and amount of used memory. Results are discussed and conclusions are made. |
