Accessing Transdata
Most of the features of Transdata can be accessed through the user interface. This is available through a Transdata icon that is available at the desktop. 

Transdata

This will open the main "Transformation data manager" screen. You can then navigate to all the features of Transdata through the buttons and selection lists. Another method to access Transdata is through the macros. This includes

• %finddup - Finds duplicate variable names in the transformation models.
• %join - Join input data used in transformation for final output data.
• %print_model - Generate an output report for all models.
• %trans - Transfer the data model to a new structure as specified by a specification.
• %verification_rep - Generate verification reports for review of transformation.

Transdata also generates code that you can submit in batch mode. This allows you to transform many datasets in an efficient manner.

Touring Transdata
The main screen entitled Transformation Data Manager is the control center listing all your source and transformation models. It contains buttons to most of the features of Transdata.

Clicking on the report button will navigate you to the report generator screen. This allows you to select the transformation objects and different types of reports.

You can also join datasets and have the merge program generated through join screen.

New transformation model information can be configured or an existing transformation can be edited through the transformation data screen. This contains attributes pertaining to the transformation.

The transformation model can be edited with CDISC recommended attributes with the edit transformation model screen.

You can create programs from the many tools within Transdata. The programs can be viewed and edit through the edit code screen.

Transdata Work Flow
The main goal for Transdata is to read in source data and transform it to a standardized destination dataset. In the process, the transformation is stored in a transformation data model.  The following components are involved within in this process.

• Source Data - These SAS datasets that are read in as input to be transformed.
• Transformation Model - Transdata stores the transformation information pertaining to datasets in datasets.  These datasets are referred to as transformation models or models for short.
• Transformation Code - The system generates code used to perform the actual data transformation. 
• Output Data - These SAS datasets that are the result of the data being transformed.

The workflow for Transdata is as follows:
