Continuing with my school-project, now I have to estimate the size of the database from here to 5 years. They give me a formula, so, in that formula, one of the values is the size of the empty database (when it is created, and doesn't have any tables, index, etc.).
For example, for MySQL, I found here that it is 10 MB.
But, for Oracle, what is the size?
I don't have Oracle or any RDBMS to make queries, it is just a work of research. I've googled a little, but I haven't found for Oracle.
Any version of Oracle (9 or later) is okay.
