Unemployment represents one of the key social and economical issues of the current world. The Integrated Portal of the Ministry of Labor and Social Affairs of the Czech Republic supports unemployed people to find a proper job using various useful tools. Any user can find a job according various criteria. The existence of public transport connection between municipality of residence and municipality of potential new job is one of many various criteria of searching. Data for this option are provided and guaranteed by VSB — Technical University of Ostrava. Two types of this database are developed according to the spatial level — municipality and municipality district level. To provide updated versions of these databases three times per year, an automatic creation has been developed and utilized. This paper describes the software solution, where the whole process is automatically distributed to many powerful workstations for parallel processing of all public transport connection combinations and the current use of this database.
