ER Diagram bnaney k liye konsa software use krna hoga ?

Sir guide kr dein ....

Use ER-Studio or Visio

bhai koi restriction nhi he ap beshak word me bna lo

ERD paint mein bhi ban sakti hy... But using proper tool is more appropriate and easy...

miscorsoft visio main ER diagram banani hai

Yes. Visio is simple.

Word me table draw keren gay but demoralize kase huta ha data any idea

any one has any idea to solve this assignment. So please share it

De-normalization is reverse of Normalization. So you have to merge sub-detail tables into detail tables e.g. Team into Player & Series into Match, step by step, removing the primary keys.

I'm using pre-joining tech on One-Many relationships.
