Sequential file stores small amount of the data with any extension .txt where as DataSet stores Huge amount of the data and opens the file only with an extension .ds.

Sequentiial Stage stores small amount of the data with any extension in order to acces the file where as DataSet is used to store Huge amount of the data and it opens only with an extension (.ds ) .The Copy stage copies a single input data set to a number of output datasets. Each record of the input data set is copied to every output data set.Records can be copied without modification or you can drop or change theorder of columns.

hi all

sequential file:

it act as a source & permanent storage for target.it 's extend is .txt.

dataset:

it act as a temporary storage stage ,mainly it used before the target stage

while using this stage  the ip datas r partited &convert into internal dataset format.then it is easy to load the data in target stage .

copy:

it act as a placeholder.it has a single ip &many o/p .

if u want 2 add a new stage in ur job at that time it is very easy otherwise u have to modify that whole job.

DataSet supports parallelism but sequential file doesn't
