Codes of collecting data (country, settlement and locality). Their names are also visualized by recalling procedures from the auxiliary databases; Collection date; Code number of the location; Number of recovered parasites. Fig. 7. Parasite-host relationship at family level of the host species Auxiliary databases, named registers The Fields of the records in the main databases linked with registers are: codes of the family, genus, species and subspecies (both for host and parasite species) country, village, settlement, habitat, collector, location, area and code of parasitologist who determined the parasite. Registers contain the basic information which is required to fill in the records of the "collection book" and the "book of identified parasites". The record structure of each registers includes a field for code number and other string and numeric fields. The code numbers of the higher categories are also represented in the records of the genus, species and subspecies registers, as well as settlement and locality registers (Figs 5-6), which are necessary for further computation (e.g. to construct a taxonomic tree for search and report utilities). For GIS applications, the XY coordinates are also included into the record structure of the "settlement" register (Fig. 6). In all of the registers, the user is able to view, change and delete the records or define a new one.
