2.Yes ,it is possible to know the type of join by DDS.
If we are joining two files,with JREF(primary file) thn it will Inner join.

If we have specified JDFTVAL ,then it will become left outer join.Because all records from primary file will be selected and only matching records from secondary file will be selected.

if we are joining same file ,like,JFILE (PF01 PF01) ,this is a self join.

I know access path is the path chosen by the program to retrieve data. It can be of keyed access path or arrival sequence. *IMMED- *IMMED description says access path is updated each time record is added or deleted from a member. - What is updating here? *REBLD - The access path is completely rebuilt each time a file member is opened.
