You can use the AdventureWorks
sample databases provided from Microsoft. They provide quite realistic sample data, i.e. there are tables with huge amounts of records, there are master-details relationships, etc. In other words, they try to cover almost all real-life project scenarios that could exist. Of course, sample data is sample data, there might be real-life project which are much more complex.
Alternatively you can create dummy data in memory on the fly in any possible way that you need. There are no a rules or guidelines on how to create sample data (or examples).
This is just .NET source code. You can create sample data in infinite number of ways, for example:
Age = index,
Boolean = Convert.ToBoolean(index % 2),
JobCode = index,
RegistrationDate = DateTime.Today
Or anything else that you might need.
I hope this helps.
