RT Journal Article SR Electronic A1 Netrefová, Hana T1 Component decomposition of user interface of web information system JF Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis YR 2014 VO 53 IS 3 SP 281 OP 288 DO 10.11118/actaun200553030281 UL https://acta.mendelu.cz/artkey/acu-200503-0027.php AB At present, the usage of information systems increases in various areas of human activities, therefore it is necessary to put the emphasis on their quality and user friendliness. That is why new techniques of design, development and implementation of information systems are being sought. The author of the paper and her colleagues employ themselves in the domain of component oriented web information systems and their goal is to define the methodology for building this kind of system. The component boxing model was designed so far. It describes how to build-up the information system from the particular components at each level of the three-layer architecture in general. Within the individual levels, it is needed to carry out the detailed analysis of components and their dependencies. In the paper, the user interface is discussed. The page decomposition in particular components is analyzed in detail and the component types with relationships between them are sought. There are also terms as box, box content, box design, visual element, linked and doubly linked elements, elements linkage defined. Further way of this domain research that would lead in determination of the methodology for the information system development at the user interface and presentation level is shown as well as the integration of this particular task in the entire system development.
