问题:

I have installed Oracle XE. I build small database every day to practice from command prompt, but now I want to have more. I want to have a bigger database with a lot of different data to practice and make exercises.

So, is possible to get a big data file from somewhere and upload to XE database?

回答1:

You can't get 'big' data for Oracle Express edition as it is limited to 4GB (10g) or 10GB (11g ).

That said, there are public datasets available. Personally I like the FAA data on registered aircraft owners/operators

As you are practicing with Oracle, perhaps a good solution (which will also generate exactly the data you need) would be to write your own stored procedures to generate your data in a loop (or similar construct). You could then generate as much as you like whilst also practicing your handling of large datasets and writing of efficient PL/SQL and SQL code.

This way your data will match your current database structure too without having to build a new database matching whichever dataset you download from the web.
