The aim of the present paper is to give an overview on the issue of the archaeological investigations of the chronology of medieval settlements in Hungary. After a brief introduction dealing with theoretical and/or methodological questions, a description of the literature is given in order to explain a rather chaotical picture of a graphic image of settlement dating
. In the last chapter of the paper one can find an attempt to give a schema for a frame-like — i. e. not exact — dating of medieval settlements in Hungary
The widespread use of digitally-controlled measuring and analytical devices and electronic data collectors, all equipped with microprocessors and linked to computers, has made it possible for on-line data collection to become a routine process. A rational combination of two up-to-date techniques, barcodes and digital balance terminals, linked to an average computer background (Kuti et al., 2003), has proved in practice to satisfy the criteria raised for the up-to-date processing of breeding data at low cost. This system is an example of how it is possible to reduce costs while processing data more rapidly and reliably and allowing human resources to be utilised more flexibly and efficiently. The modules (MvLabel, MvSticker, MvWeighing)of the program package developed in Martonvásár for the handling and analysis of the data from plant breeding and crop production experiments can also be used independently for the identification of experimental field units (spikes, rows, plots) and for the online handling of weight measurements and analytical data. They provide a simple solution for the design and printing of labels (self-adhesive or plastic) containing barcodes. They make it easier to retrieve the data recorded by digital balance terminals and store them on hard discs, while also helping to unify and synchronise the various parts of the system using barcode readers to identify the measurement data.
