Summary: | 碩士 === 元智工學院 === 電機與資訊工程研究所 === 84 === Conventional alpha numerical database query methods are
limited togenerate declarative, high-level, set-oriented query
expressions, whichare not convenient for drawing data
retrievals. In our study, markup technique is introduced to
drawing data. A marked-up drawing data consists of four
fundamental structures, i.e.,hierarchy block relationship,
linking structure, attribute data, and"free-formatted" drawing
data. Based on these structures, users may finddifferent access
paths, such as get-by-navigation, get-by-retrievals, get-by-
hierarchy-traversals, or even get-by-manual-browsings. These
query methods are then integrated into a so-called Query Model,
which allows users to get drawing data, documents, and table
information together. In Static Query MAN, a primary query
path is embedded into this APsystem. In Dynamic Query MAN,
however, all query paths are integrated intothe Query Model.
Two prototyping systems, named Static Query MAN ver2.5, and
DynamicQuery MAN ver1.0, are developed. Finally, some
evaluation of various query paths based on different approaches,
such as SQL query method or the interactive query process
developed in this research, are discussed.
