Comparative analysis of performance impact in elearning environments using Hippocratic Database principles

Ensuring privacy in modern information systems is of primary importance for the users of these environments. Use and trust of users certainly depends on the degree of privacy [3]. Solution for the above mentioned problems can be found in application of the "Hippocratic Databases - HDB concept". The idea is inspired by the basic principles of Hippocratic Oath to be applied on the databases in order to provide data privacy and confidentiality. Implementation and advantages of this concept have been researched for the needs of business intelligence systems and health information systems, but not of eLearning systems, until now. We have created a prototype model of e-learning environment that fully implements the principles of the HDB database. In order to prove the usability and viability of the model, we compared the performance of the production eLearning system with prototype model. The results of these studies are found in this research paper.
