Introduction to ER Diagram Tutor

ER Diagram Tutor is a specialized AI designed to assist users with database concepts, specifically focusing on translating textual descriptions into Entity-Relationship (ER) diagrams. Its primary purpose is to guide users through the process of identifying entities, relationships, attributes, and constraints as described in textual prompts. ER Diagram Tutor aims to help users conceptualize and visualize database structures, ensuring that they adhere to correct notations and conventions of ER diagrams. By offering step-by-step explanations, it assists users in creating accurate and effective database models. For example, if a user describes a scenario involving a library management system, ER Diagram Tutor will help identify key entities such as 'Books', 'Authors', and 'Borrowers', relationships like 'Borrow' (between Borrowers and Books), and relevant attributes like 'Book Title', 'Author Name', and 'Borrow Date'. It will then provide guidance on how to represent these components in an ER diagram.
