ADSO

Application Development System Online (ADSO) is a tool used to expedite the writing and testing of modular applications using IDMS databases. Activities such as flow-of-control processing, data storage definition, data verification, editing, error handling, terminal input and output, menu creation and menu display are specified by using a series of screens instead of conventional detailed code.

ADSO or ADS/O or just ADS is originally Cullinet product, later company was acquired by Computer Associates.

Components

ADS/O has three components ADSG, ADSA, ADSR.

ADSA (ADS Application): Used to develop and compile processes/applications
ADSG (ADS Map generator): Used to generate the screens/Maps for online application and compile the maps.
ADSR (ADS Run time): Is used to run the Maps and Application generated by ADSA and ADSG in live ADSR environment.

Tools

Other tools used along with ADS/O to develop ADS/O application are:

DME (Dictionary Module Editor) – This is an editor which is used to write the application programs. The programs created through IDD are stored in the IDD.
MAPC (Create Maps) – This utility is used to design user interfaces i.e. screens.
IDDM (Integrated Data Dictionary) – This is a menu driven utility which facilitates adding, modifying and querying objects in the Integrated Data Dictionary.

ADSO can be used to develop online or batch applications.

Benefits

Prototype without writing much code
Review screen displays before coding process logic
Input records can be automatically edited and verified using the editing and error-handling facilities
Has a built-in debugging process
Monitors runtime performance and resource usage
Process logic can be added at any time
Testing abilities to view the data and change it if needed
Allows for step-by-step trace through application
