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. Standard Transformations in the Process Library Data Transforms Folder 219 Name Description Summary Statistics - Report creates an HTML report that contains summary statistics. Summary Tables - 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. .
