APPLICATION DEVELOPMENT SYSTEM / ONLINE

INTRODUCTION

The CA-ADS is a tool used to develop modular applications.

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.

Add process logic Process and retrieve data from

IDMS database, Online entries,

3

Typical steps when creating a CA-ADS application

• Data analysis• User requirements• System requirements

• Define the application structure (Online tool: ADSA)

• Define the prototype maps (Online tool: MAPC)

• Define the prototype dialogs (Online tool: ADSC)

• Create the process module (Online tool: IDD)

• Enhance maps and dialogs (Online tools: MAPC, IDD)

Analyze the system

Develop an executable prototype

• Implement production application

Develop the test application

4

ADS Application Components Application Functions (A named procedure or activity

within an application) Dialogs (A dialog enables interaction

between the user and the application)

5

ADS Application Components

Responses A named entity that establishes a relationship

between two functions Processing control is directed by the valid

responses of a function The screen may list valid responses A response can be a control key or A response value entered in the response field

by the user

6

Processes Maps Sub-schemas Data Records Tables

7

ADS Application Structure

8

ADS Features Scratch Management

Temporary storage Access by Name, Record Id Currency maintenance

Queue management Recoverable across system shutdown Sequentially, Randomly accessible Automatic Trigger Initiation Randomly Delete-able Both-end insertion

9

ADS Features Different types of Control flow

Execute next function Invoke dialog Link dialog Transfer dialog Return [dialog] Leave Display Continue

Subroutines Include modules

51

ADS/O Process Commands

Arithmetic commands

Add

Compute

Divide

Move

Multiply

Subtract

52


Conditional commands

IF/THEN/ELSE - NEXT Conditional testing

WHILE/EXIT repeats the commands

DO/END executes the group of commands

Subroutine Control Commands

CALL passes control to predefined

subroutines

DEFINE defines subroutine

GOBACK terminates subroutine

INCLUDE includes source code in a process

53


Dialog Control Commands

Invoke passes control to lower level dialog

Leave Terminates ADS/O application

Link passes control to lower level dialog

Return Returns controls to calling dialog

Transfer Transfers control to a dialog at

same level

Execute next function - Terminates a response process

54


Queue Commands

Delete queue delete queue

records

Get queue retrieve queue

records

Put queue stores queue

records

55


Scratch Commands

Delete scratch

Get scratch

Put scratch

Data base access Commands

Accept, Commit, Connect, Disconnect, Erase, Find, Get,

Keep, Modify, Obtain, Ready, Return DB-Key, Rollback, Store,

Map Commands

Display Map

Modify Map

56


Utility Commands

Abort - aborts an application

Accept - retrieves runtime status info like

user-id, dialog name, terminal identifiers

Commit Task - writes a check point & releases

locks

Initialize records - reinitializes record buffers

Rollback Task - initiates task recovery procedures

Snap - requests a snapshot dump

Write printer - transmits data to a printer

57

Map display Commands

Display

to display Map on the terminal screen

mapout function

normally premap process ends with display command

can be used in response process too

Display continue

used in response process to display the map by

reexecuting the premap

DISPLAY MESSAGE TEXT IS 'INVALID PF KEY - REENTER'

58

Dialog control Commands

Invoke

passes control to a lower level dialog in the application structure

INVOKE “dialog name”

Return : passes control back in invoking dialog (map is displayed)

Return continue : passes control back in invoking dialog premap

process

Link

passes control to another dialog or program ( lower level )

Return : passes control to the next command in sequence

59

Dialog control Commands

Transfer

passes control to another dialog at same level,

first dialog becomes non operative

second dialog becomes operative

to go back to first, need to use Link/Invoke/Transfer

Leave

to terminate ADS/O application

control is passed back to Runtime system

60

Map Commands

Attribute commands

To change the attributes of the map fields

Ex: Brighten, Normalize, Protect & Unprotect

Modify Map

a single command to change no. of map fields

61

Do-end

if ’’’condition’’’

then

do.

--------------

--------------

end.

Else

do.

--------------

--------------

end.

62

While ‘’’ condition’’’

repeat.

-----------------------

----------------------

end.

Call subrtn-name.

Define subroutine subrtn-name.

Goback.

63

Like work records

allows to pass info between dialogs or programs

Maintained in data dictionary

Scratch records

data stored from dialogs executed at same terminal

cleared at the time of system start

Queue records

data stored from dialogs executed from any terminal

data maintained for few days even across system shutdowns

commands : PUT/GET/DELETE

Queue & Scratch management
