The thesis deals with the topic of basic registers and specific agendas' activity roles that are analyzed based on a questionnaire survey. It gives the basic overview of e-Government and the basic registers of public administration as part of e-Government. Based on the questionnaire survey conducted on particular Land Register and Register offices the structure and definition of the agenda activity roles are evaluated and the thesis identifies the intensity of various activity roles use in practice. It is concluded that the activity roles of A124 agenda are defined in the way that approximately corresponds to the actual execution of the agenda and that all the roles are actually more or less in use. On the contrary, when it comes to A414 agenda, the number of reported roles is quite maximalist. The thesis reveals that some of the activity roles are not being executed in practice at all, or they are in use only at certain offices. 67 % of both A124 and A414 agenda activity roles were proved to be defined the way that fully corresponds to the actual use of these agendas. These activity roles are being used quite often.
