 Hi @Fathima C S 

To create a diagram in Lucidchart, after into a new document and drawing entities, represented by rectangles, to symbolize tables. Within each rectangle, add attributes, or columns, to provide further detail. Identify primary keys with a PK symbol and foreign keys with an FK symbol.

Next, establish relationships between entities by drawing lines or connectors, labeling each connection with a clear description of the relationship type, such as "manages" or "teaches".

Finally, organize the layout to ensure a logical flow, arranging entities so that relationships unfold from top to bottom and left to right, creating a clear and easy-to-follow visual representation.

Get a head start with pre-designed templates that are ready to use
