Please design a comprehensive experiment of database recovery to complete the following functions in order:
1. Take a backup of database Example;
2. Modify, insert or delete EMP data with at least two operations, and then make an incremental backup x;
3. At least three operations: modify some data OP1, delete all employee data for deptno=1, insert some data OP3, and then make an incremental backup x+1;
Now assume that OP2 is a microoperation, please design backup and restore scheme and implement it.
