Answer Posted / anand r
ESDS
in batch it acts like a flat file
organizanition-sequential
Accessmode is sequential
in online we can read and write the records random manner
by using the key field
KSDS
Access mode: sequential,random and dynamic is possible
like indexed file
RRDS:
like KSDS we can use all the access modes and records are
accessed using RID (record identification No) thats
relative key
