Theinput design is the link between the information system and the user. Itcomprises the developing specification and procedures for data preparation andthose steps are necessary to put transaction data in to a usable form forprocessing can be achieved by inspecting the computer to read data from awritten or printed document or it can occur by having people keying the datadirectly into the system. The design of input focuses on controlling the amountof input required, controlling the errors, avoiding delay, avoiding extra stepsand keeping the process simple.
The input is designed in such a way so that itprovides security and ease of use with retaining the privacy. Input Designconsidered the following things:Ø Whatdata should be given as input?Ø How the data should bearranged or coded?Ø The dialog to guide theoperating personnel in providing input.Ø Methodsfor preparing input validations and steps to follow when error occur. OBJECTIVES 1.
Input Design isthe process of converting a user-oriented description of the input into acomputer-based system. This design is important to avoid errors in the datainput process and show the correct direction to the management for gettingcorrect information from the computerized system. 2.
It is achieved bycreating user-friendly screens for the data entry to handle large volume ofdata. The goal of designing input is to make data entry easier and to be freefrom errors. The data entry screen is designed in such a way that all the datamanipulates can be performed. It also provides record viewing facilities.3. When the data isentered it will check for its validity.
Data can be entered with the help ofscreens. Appropriate messages are provided as when needed so that the user will not be in maize of instant. Thus theobjective of input design is to create an input layout that is easy to follow
