Name the three major set of files on disk that compose a database in Oracle.
There are three main sets of files on disk that compose a database. All the files are binary. These are
1.) Database files
2.) Control files
3.) Redo logs

Without these files, you cannot access the database, and the database administrator may have to recover some or the entire database using a backup, if there is one.
