Miről mesélnek a kora újkori középiskolai adatsorok?

In spite of the fact that the Society of Jesus had a quasi-monopoly position in Catholic ecclesiastical secondary education in the Kingdom of Hungary and Transylvania in the 17th and 18th centuries, until recently, registers of Jesuit grammar schools have not been utilised sufficiently. As referred to in the title, the study examines the possibilities of the electronical processing of the school register of the early modern Jesuit Grammar School in Kassa (Košice, present-day: Slovakia), introducing the first results. The project has started within the confines of the subproject of the “MTA–ELTE History of Universities Research Group” as a continuation of the project called “Catholic Schooling in Hungary in the Early Modern Period: the Students of the Győr, Nagyszombat and Pozsony Jesuit Colleges”. As results of the latter project, the school registers of the Jesuit grammar schools in Győr, Pozsony (Bratislava, present-day: Slovakia) and Nagyszombat (Trnava, present-day: Slovakia) had been already processed electronically and student databases had been created, which are currently available at the Hungaricana – Hungarian Cultural Heritage Portal. The importance of these student databases, including the Kassa one, lies primarily in the potential of complex queries. Statistical data series can be produced by using of them from an essentially pre-statistical period, which could provide a sharper insight into a well-defined broad segment of society of the early modern Kingdom of Hungary. Moreover, cohort analyses based on them could contribute to revealing school studies and educational paths, providing opportunities to make inductive reasonings. Nevertheless, especially combined with other databases, hopefully those will be also useful for researchers dealing with information history, because they aid to draw higher-order conclusions through the various logical queries.
