Create Match Code and Apply Lookup Standardization Transformations

The Process Library tree includes two transformation templates that require SAS Data Quality Server software: Create Match Code and Apply Lookup Standardization These transformations enable you to increase the value of your data through data analysis and data cleansing

To use these transformations, the SAS Data Quality Server software must be installed, a SAS application server must be configured to access a Quality Knowledge Base, and the Quality Knowledge Base must contain the locales that you need to reference in your SAS Data Integration Studio jobs When the prerequisites have been met, you can drag and drop these transformations into your process flow diagrams

SAS Data Quality Functions in the Expression Builder Window

SAS Data Integration Studio provides an Expression Builder window in the properties window of some transformations (For a description of this window, see

“Expression Builder Window” on page 16.) If SAS Data Quality Server software is available to you, the Expression Builder window includes a wide range of data quality functions One way to see the data quality functions is to open the properties window of

the SQL Join transformation and select the Where tab For detailed information about

the data quality functions, see the SAS Data Quality Server: Reference, which is

available in the online SAS Help and Documentation for Base SAS and in SAS OnlineDoc

Data Validation Transformation

When incorporated into SAS Data Integration Studio jobs, the Data Validation transformation enables you to detect error conditions and specify responses to those errors Error conditions include blank or missing values, duplicate values, and invalid values The actions that you can take in response to erroneous values include stopping the job, changing the value, or writing the row to an error table instead of to the target The Data Validation transformation does not require SAS Data Quality Server software

Using a Physical Table to Update Table Metadata

The Update Table Metadata feature compares the columns in a physical table to the columns that are defined in the metadata for that table If column metadata does not match the columns in the physical table, the metadata is updated to match the physical table

For existing tables, the Update Table Metadata feature adds new columns, removes deleted columns, and records changes to all column attributes When you select and run this feature against one or more tables simultaneously, the update log lists which tables have been successfully updated and which have failed

When you use the Update Table Metadata option on a physical table in DBMS format and the DBMS table has more than one schema, the Update Table Metadata option selects the first schema The Update Table Metadata feature uses the following resources: the current metadata server and the SAS application server to read the physical table the current metadata server to update the metadata to match the

physical table

You are prompted to provide a user name and password for the metadata server if this was not already saved with the current metadata profile If you have not provided

a user name and password for the SAS application server during the current session, you are prompted to provide them A warning message displays if the SAS Workspace Server component of the SAS application server is older than SAS 9.1.3, Service Pack 3 Follow these steps to use the Update Table Metadata feature:

1 If you are working under change management, check out one or more tables that contain the metadata that you want to update

2 From the Project tree, select one or more tables for which you want to update the

metadata and then select Update Table Metadata from the Tools menu.

You might be prompted to supply a user name and password for the relevant servers When the update is finished, you can choose to view the resulting SAS log

Updating Metadata for Transformations

Overview

A transformation is a metadata object that specifies how to extract data, transform data, or load data into data stores A number of standard transformations are provided

in the Process Library for SAS Data Integration Studio For a description of the standard transformations, see Appendix 1, “Standard Transformations in the Process Library,” on page 217

There are two main reasons to update the metadata for a transformation:

3 to update the default metadata for a transformation when it is first added to a job

3 to change the behavior of a transformation in a process flow Use the property window for a transformation to update its metadata For a description of the transformation properties window, see “Transformation Properties Window” on page 27

Update the Default Metadata for a Transformation

When you drag a transformation template from the Process Library and drop it into the process flow for a job, the default metadata for the transformation is mostly blank You must update the default metadata according to your goals for that transformation

in the process flow

The general steps for updating the default metadata for a transformation are described in “Update the Job as Needed” on page 100

Examples of how to update the default metadata for transformation are provided in Chapter 10, “Example Process Flows,” on page 149 To see more examples of how to update the default metadata for transformations, follow these steps to display the relevant Help topics:

1 From the SAS Data Integration Studio menu bar, select Help I Contents The

online Help window displays

2 In the left pane of the Help window, select Examples I Process Library Examples.

Other Updates to the Metadata for a Transformation

After you have made the initial updates to the default metadata for a transformation, you might have to update the transformation again later For example,

you might need to change the options on the Options tab for the transformation The

following steps describe one way to update the metadata for a transformation Assume that the metadata for the job that contains the transformation is currently checked into

a change-managed repository

2 In the Inventory tree, expand the Jobs folder.

6 Use the tabs in the properties window to make changes to the metadata for the

transformation Each tab has its own Help button.

8 Close the Process Designer window and save your changes to the job

Setting Name Options for Individual Tables

Overview

SAS Data Integration Studio cannot access tables or columns with case-sensitive names or with special characters in the names unless the appropriate options have been specified in the metadata for the table

Prerequisites

For tables in DBMS format, it is assumed that the appropriate name options have already been set for the database library that is used to access the table, as described in

“Supporting Case and Special Characters in Table and Column Names” on page 73 Name options do not need to be set on the library that is used to access a table in SAS format

Task Summary

The following steps describe one way to enable name options for a table whose

metadata has been saved to a metadata repository It is assumed that the metadata repository is under change management

2 In the Inventory tree, open the Tables folder or the External Files folder.

3 Select the table that you want to update, then select Project I Check Out The

metadata for the table is checked out A check mark is displayed next to the table

in the Inventory tree An icon indicating a checked-out table appears in the

Project tree

4 In the Project tree, select the metadata for the table, then select FileI

Properties from the menu bar The properties window for the table is displayed.

5 In the properties window, click the Physical Storage tab.
