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. The access path is maintained until the
member is
closed, then the access path is deleted. - I am not able to
understand this completely.
Could anyone explain these more clearly?

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.
