Design a Software Engineering CASE Tool (ERToOracle10g) to transform a graphical Entity Relationship model (ER model) to Oracle10g

CASE Tools play a significant role in the field of software engineering development processes where they are utilized in system modeling and analysis, in system design and in generating automatic software codes based on system design models.
In this research the (ERToOracle10g) tool has been designed and implemented as a CASE Tool. Hence it is used to construct a data modeling using ER Model, then transforming the graphical model to (Oracle 10g) SQL instructions and executing it automatically inside an (Oracle 10g) server. XML has been used to transform graphical ER model to SQL instructions. The graphical ER model includes symbols and shapes that are difficult to analyze or to directly generate SQL instructions. The graphical model is transformed to descriptive text using XML which is easy to analyze and transform to SQL instructions.
