ADSO
Application Development System Online 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 : Used to develop and compile processes/applications
- ADSG : Used to generate the screens/Maps for online application and compile the maps.
- ADSR : 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 – This is an editor which is used to write the application programs. The programs created through IDD are stored in the IDD.
- MAPC – This utility is used to design user interfaces i.e. screens.
- IDDM – This is a menu driven utility which facilitates adding, modifying and querying objects in the Integrated Data Dictionary.
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
