Can anyone find me a data model i can use for my coursework?

We are allowed to take an existing data model from the internet

it needs to have all these:

• At least one one-many relationship
• At least one decomposed many-many relationship-show the original many-many relationship
• At least one recursive relationship
• At least one one-one relationship
• An entity with subtyping that has relationships with other entities that involve the super-type and at least one subtype.
• No less than 8 entities, no more than 10

i'm finding it hard to find a data model with a recursive relationship or "An entity with subtyping that has relationships with other entities that involve the super-type and at least one subtype." (i'm not quite sure what that means?)

could anyone suggest to me what data model i could use or link me to one that has all of these aspects?

Thanks

actually it's almost a certainty that the lag was on the dbforums server

good luck with picking a data model

be aware that other students looking for data models will also find that site
