learning environment (Learning Management System(LMS)) was necessary:LMS = R, K , K(R).The following requirements ( R)were laid down for it:• Automated course generation and e-learningmaterial preparation possibilities;• Textual and multimedia content;• Customers self-registration and data protection;• Tests generation;• Test questions databases set generation;• Cross linking of databases;• Automated multi-session examination;• Remote Web content management;• Variable search options and reports generation;• Multi-course management.Each selected LMS was evaluated by the followingcriteria ( K ):• Belonging to the open source and freewaresolutions;• Convenient maintenance;• Affordable price.Unfortunately, it should be pointed out that not onlyfive years ago, but also now, it would not be easy to findsuitable LMS (EduTools 2006), which would conform tothe abovementioned requirements. Therefore, thepartners elaborated their own cost-effective LMS (seehttp://www.teachsys.com) allowing to save money andintroduce necessary modifications in short time limits.DM of LMS TeachSys isbased on relationships of five data sets (see Figure 2):Datalogical model ( )DM = LM , Questions,C DB , Test,Exam, whereLMcourses;QuestionsCDBcourses;TestExam- e-learning material of different- total set of test questions;- test questions data bases of different- test questions data sets;- examination questions sets.Figure 2.
