Frequently Asked Questions About AI Entity Relationship Diagram Generator
Common questions and answers about our AI-powered ER diagram generation tool.
What is an Entity Relationship Diagram?
An Entity Relationship Diagram (ERD) is a visual representation of a database schema showing entities (tables), their attributes (columns), and relationships between entities. It's essential for database design and documentation.
What types of relationships can the AI detect?
The AI can detect and represent all standard relationship types: one-to-one (1:1), one-to-many (1:N), and many-to-many (M:N) relationships with proper cardinality notation including optional and mandatory participation.
Does it support primary and foreign keys?
Yes! The AI automatically identifies primary keys (PK) and foreign keys (FK) in your description and marks them appropriately in the ER diagram, ensuring referential integrity in your database design.
Can I use these ER diagrams for actual database implementation?
Absolutely. The generated ER diagrams can serve as blueprints for creating actual database schemas. They're suitable for use in database documentation, technical specifications, and can guide SQL table creation.
