Registering Data Targets Specify Physical Storage Information for the New Table 145 Specify Physical Storage Information for the New Table Use the physical storage window to specify the format and location of the table that you are registering, as shown in the following display. Display 9.6 Physical Storage Window In this window you specify the database management system that is used to create the target, the library where the target is to be stored, and a valid name for the target. Follow these steps: 1 Because the target is a SAS data set, in the DBMS field, accept the default value of SAS. 2 In the Library field, use the selection arrow to select Report Table Lib. 3 In the Name field, enter a valid SAS name for the target. (For details about SAS names, see the SAS Data Integration Studio Help.) For this example, accept the default: Total_Sales_By_Employee. 4 When you are finished specifying physical storage information, click Next. The Custom tree group selection window displays. Usage Hints for the Physical Storage Window Remember the following as you use the physical storage window: The name that you specify in the Name field must follow the rules for table names in the format that you select in the DBMS field. For example, if SAS is the selected DBMS, the name must follow the rules for SAS data sets. If you select another DBMS, the name must follow the rules for tables in that DBMS. For a SAS table or a table in a database management system, you can enable the use of mixed-case names or special characters in names. See “Setting Name Options for Individual Tables” on page 109. You can specify new libraries or edit the metadata definitions of existing libraries using the New and Edit buttons. 146 Specify a Custom Tree Group for the Current Metadata Chapter 9 You can use the Table Option button to specify options for SAS tables and tables in a DBMS. Specify a Custom Tree Group for the Current Metadata Use the Select Group window to specify a Custom tree group for the table that you are registering. A Custom tree group is a folder that you can use to keep similar kinds of metadata together in the Custom tree on the SAS Data Integration Studio desktop. Display 9.7 Select Group Window For this example, assume that you do not want to specify a Custom tree group for the table. Select Foundation and click Next. The finish window displays. Registering Data Targets Check In the Metadata 147 Save Metadata for the Table Use the finish window to review the metadata that you entered. Display 9.8 Finish Window If the metadata is correct, click Finish. The metadata for the table is written to a current metadata repository. Note: The table does not yet exist on the file system. You have only specified the metadata that is used to create the table. At this point, you could add the metadata that you just created to a job, or you could check in the metadata. Check In the Metadata Follow these steps to check in the metadata for the target table: 1 In the Project tree, select the repository icon. 2 From the SAS Data Integration Studio menu bar, select Project Check In Repository. All objects in the project repository are checked into the change-managed repository. The new table is now ready to be used in a job, as described in “Example: Creating a Job That Joins Two Tables and Generates a Report” on page 150. 148 Next Tasks Chapter 9 Next Tasks After you have specified the metadata for one or more targets, you can specify metadata for the job that will read the appropriate sources and create the desired targets on a file system. 149 CHAPTER 10 Example Process Flows Using Jobs to Create Process Flows 149 Example: Creating a Job That Joins Two Tables and Generates a Report 150 Preparation 150 Check Out Existing Metadata That Must Be Updated 151 Create the New Job and Specify the Main Process Flow 151 (Optional) Reduce the Amount of Data Processed by the Job 153 Configure the SQL Join Transformation 155 Specify Column Mappings 155 Change One Column to a Calculated Column 157 Specify GROUP BY Options for the Join 160 Update the Metadata for the Total Sales By Employee Table 161 Configure the Loader Transformation 161 Run the Job and Check the Log 162 Verify the Contents of the Total_Sales_By_Employee Table 163 Add the Publish to Archive Transformation to the Process Flow 163 Configure the Publish to Archive Transformation 166 Run the Job and Check the Log 166 Check the HTML Report 167 Check In the Metadata 167 Example: Creating a Data Validation Job 167 Preparation 167 Create and Populate the New Job 168 Configure the Data Validation Transformation 170 Run the Job and Check the Log 172 Verify Job Outputs 173 Example: Using a Generated Transformation in a Job 174 Preparation 174 Create and Populate the New Job 175 Configure the PrintHittingStatistics Transformation 176 Run the Job and Check the Log 178 Verify Job Outputs 179 Check In the Metadata 179 Using Jobs to Create Process Flows After you have specified the metadata for one or more sources and targets, you can specify metadata for the job that will read the appropriate sources and create the desired targets in physical storage. Use the examples in this chapter, together with the general steps that are described in “Creating, Running, and Verifying Jobs” on page 99, to specify jobs that will create and load the desired targets. . In the Name field, enter a valid SAS name for the target. (For details about SAS names, see the SAS Data Integration Studio Help.) For this example, accept the default: Total_Sales_By_Employee. 4. tree group is a folder that you can use to keep similar kinds of metadata together in the Custom tree on the SAS Data Integration Studio desktop.
