Tasks and Requirements: Review the original E/R diagram and the instructor's feedback. Follow the additional instructions and concepts provided in Module 3. Incorporate appropriate enhanced E/R concepts, such as specialization, generalization, and inheritance, where applicable. Ensure that entities, attributes, relationships, cardinalities, and participation constraints are represented correctly. Create a clear, accurate, and well-organized EER diagram. Provide the final diagram in an editable format, along with a brief explanation of the changes. Required Skills: Strong knowledge of database design and E/R modeling. Experience creating EER diagrams. Familiarity with entity relationships, cardinality, and specialization/generalization. Ability to follow academic instructions and instructor feedback accurately. Deliverables: Revised and enhanced E/R diagram. Editable source file. Brief explanation of the revisions made. Please review the provided files and instructions before starting. I am looking for accurate work that follows the assignment requirements and helps me understand the enhanced E/R modeling concepts. When applying, please mention your experience with database design and EER diagrams, along with your estimated completion time and fixed price.
