The chapter describes
the data preparation activities that can be performed with the data
preparation interface. The following list identifies the available
actions:
-
select a source table and join
tables based on join conditions
-
add calculated columns and drop
columns from source and joined tables
-
control the sort order for the
output data and apply row filters to subset the data
-
-
add the prepared data to HDFS
With this feature set,
the data preparation interface enables administrators to access data
from the variety of data sources that SAS and the
SAS/ACCESS interfaces
can read and then operate on the data. Administrators can control
the variables needed for analytics and make the data available to
the SAS LASR Analytic Server
for in-memory analytic processing.
