| Abstract [eng] |
Analysed goals of forward and reverse data engineering and proposed to perform the transformations of data schemes through three stages: an attribute reaggregation, is_a relationships transformations and adding the methods to abstract data types scheme. Proposed to use inclusion, functional, compound functional and is_a relationships dependences in the processes of the reverse engineering; these dependencies are collected in the processes of the reverse engineering and expressed in the semantic data model. There are created rules for generation of is_a relationships from compound functional and inclusion dependences. There is made the graphic interface to specify an object-oriented scheme and there is provided possibility for generation of the object-oriented database description in the graphic editor. |
