Abstract
Reverse engineering is one of the important operations performed on programming codes to get their design presented graphically. Reverse engineering is performed on various types of databases to get their particular designs represented by different models of relationships.
In this paper, we found that a tool for performing reverse engineering on Oracle10g database located inside Oracle10g server , It has been designed in order to get its entity relationship model. Oracle10g data dictionary has been considered in performing reverse engineering. This dictionary includes all information that describes databases which is utilized for getting the important information relevant to the tables. It was necessary for presenting the entity relationship model. XML tags have been used in presenting the information of the data dictionary. These tags were utilized in creating the graphical entity relationship model.
