The optimum language for ADS/Online replacement is based on centralization, processing speed and platform preferences requirements. ATERAS ADS/Online applications will differ based upon the target platform and languages selected.

Conversion Components

ATERAS uses DB-Shuttle™ to convert all ADS/Online component types and hundreds of customization options are possible:

• ADS/Online Dialogs and all related process modules
• IDD Records and Modules
• IDMS Database Access Calls
• IDMS Maps
• IDMS ADSA Structures, including security
• IDMS Edit and Code Tables
• IDMS Automatic Editing
• IDMS-DC Scratch and Queue processing
• IDMS-DC Printing

Architecture

All IDMS ADS/Online dialog conversion includes generation of a multi-tiered architecture that ensures each replacement dialog performs exactly as the original ADS/O:

• Presentation Layer
  Replace ADS/Online functionality formerly handled by the IDMS ADS run-time system
• Map Edit Layer
  Perform editing and formatting functions formerly handled within the IDMS map and the ADS/Online run-time system
• Business Layer
  Replace IDMS process modules formerly stored in the Integrated Data Dictionary
• Database IO Layer
  Perform SQL database access and updates

Conversion of IDMS ADS/Online applications also includes replacement of components that are not specific to the ADS/Online language itself:

• ADSA Structure Definitions
  Application flow-of-control replacement module
• ADSA Security
  Application subsystem delivered in language of choice to replace the security processing formerly handled by the IDD and ADSA
• Task Definitions
  IDMS task code and application task replacement

IDMS ADS/Online conversion is no longer a manual, time-consuming, error-prone process. The DB-Shuttle™ automation technology ensures the ADS/Online conversion produces a functionally equivalent relational application.
