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 4 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

-Report

creates an HTML report that contains summary tables

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
