The following is a brief description of the major components of 
                  		  Data Manager: 
                  		
               
 
               		
               
                  		  
                  			 
                  - Data Builder
                     			 
                  
- The core 
                     				Data Manager module that enables you to take inventory of your data, and store information in the 
                     				Data Manager Knowledge Base, which resides on z/OS. Data Builder works with both Data Masking and Data Subset Extraction.
                     			 
                  
- Data Masking
                     			 
                  
- The module that enables you to generate a test environment where personal and sensitive data has been made anonymous by using
                     predefined or customized masking routines.
                     			 
                  
- Data Subset Extraction
                     			 
                  
- The module that enables you to generate a test environment where a consistent and congruent subset of data has been extracted
                     to allow for a manageable volume of data.
                     			 
                  
- Workspace
                     			 
                  
- A two-dimensional working environment definition from which you can categorize and classify data stores for your test environment.
                     			 
                  
- Data Manager Knowledge Base
                     			 
                  
- A collection of tables within a database that contain all information about catalogued files, including properties and processing
                     rules. The Knowledge Base for the 
                     				Data Manager for z/OS solution is a Mainframe DB/2 repository located in your z/OS environment.
