About the Process Library
Overview of the Process Library
The Process Library tree is one of the hierarchical lists in the tree view on the SAS
Data Integration Studio desktop. It displays a collection of transformation templates. A
transformation template is a process flow diagram that includes drop zones for
metadata that the user must supply. A template typically consists of a transformation
object and one or more drop zones for sources, targets, or both.
The Process Library organizes transformations into a set of folders, such as the
Access folder for transformations that you can use to read or write specific kinds of
data, and the Analysis folder for transformations that you can use to analyze data in
various ways.
218 Access Folder Appendix 1
Access Folder
The following table describes the transformations in the Access folder in the Process
Library.
Table A1.1 Access Folder Transformations
Name Description
File Reader reads an external file and writes to a target. Added automatically to a process flow
when an external file is specified as a source. Executes on the host where the
external file resides, as specified in the metadata for the external file.
File Writer reads a source and writes to an external file. Added automatically to a process flow
when an external file is specified as a target. Executes on the host where the
external file resides, as specified in the metadata for the external file.
Library
Contents
creates a control table to use with an iterative job, a job with a control loop in which

one or more processes are executed multiple times.
SPD Server
Table
Loader
reads a source and writes to a SAS SPD Server target. It is automatically added to a
process flow when a SAS SPD Server table is specified as a source or as a target.
Enables you to specify options that are specific to SAS SPD Server tables.
Table
Loader
reads a source table and writes to a target table. Added automatically to a process
flow when a table is specified as a source or a target.
Analysis Folder
The following table describes the transformations in the Analysis folder in the
Process Library.
Table A1.2 Analysis Folder Transformations
Name Description
Correlations creates an output table that contains correlation statistics.
Correlations
- Report
creates an HTML report that contains summary correlation statistics.
Distribution
Analysis
creates an output table that contains a distribution analysis.
Distribution
Analysis -
Report
creates an HTML report that contains a distribution analysis.
Forecasting generates forecasts for sets of time-series or transactional data.
Frequency
Frequency -

Report
creates an output table that contains frequency information.
Summary
Statistics
creates an output table that contains summary statistics.

Control Folder
The following table describes the transformations in the Control folder in the Process
Library.
Table A1.3 Control Folder Transformations
Name Description
Loop marks the beginning of the iterative processing sequence in an iterative job.
Loop End marks the end of the iterative processing sequence in an iterative job.
Return Code
Check
provides status-handling logic at a desired point in the process flow diagram for a
job. Can be inserted between existing transformations and removed later without
affecting the mappings in the original process flow.
Data Transforms Folder
The following table describes the transformations in the Data Transforms folder in

the Process Library.
Table A1.4 Data Transforms Folder Transformations
Name Description
Append creates a single target table by combining data from several source tables.
Apply
Lookup
Standardization
applies scheme data sets to transform source columns.
Create
Match Code
establishes relationships between source rows using match code analysis or cluster
analysis.
Data
Transfer
moves data directly from one machine to another. Direct data transfer is more
efficient than the default transfer mechanism.
Data
Validation
cleanses data before it is added to a data warehouse or data mart.
Extract selects multiple sets of rows from a source and writes those rows to a target.
Typically used to create one subset from a source. Can also be used to create
columns in a target that are derived from columns in a source.
Fact Table
Lookup
loads source data into a fact table and translates business keys into generated keys.
