Designing a New System

After analysing the system the analyst has to design a new software ,programs,fourms etc...
In short design a new system different than the old one.

In most cases the new system will be computer-based. The ease with which computers can communicate and process data means that are usually the best tool for the job.

In the designing stage the analyst has to design most of the system parts like:
1- Designing the System Inputs
2- Choosing the Best Data Capture and Data Input Methods for the System
3- Designing On-Screen Forms for Data Input
4- Setting Data Validation Techniques
5- Setting Data Verification Techniques
6- Designing the System Processes
7- Designing the How the Data Will be Processed
8- Designing the System Outputs
9- Designing Printed Reports

1- Designing the system inputs :

To get data into a system is a two-part process:

- Data must first be ‘captured’ (collected in a way that then makes it easy to input)

- Data must be input into the computer

The systems analyst will select a data capture method and data input method that best suit the requirements of the new system.

Data capture and input methods:
* Manuall
* Paper Forms (Form can be a simple ones with spaces for numbers and text to be written in. The data form this form would then be typed into the computer)
Forms can also be machine-readable, such as OMR forms

* Barcode Reader (Barcode readers capture the numeric code that the barcode represents.
Typically used with POS systems and also stock-control systems)

* Card Reader (Many cards contain data stored on a magnetic strip or in a small bit of memory (smart cards) which can be captured with a card reader,used in systems such as EFTPOS)

* Camera ( Capture still or moving images which can then be input to a computer for processing)

* Fingerprint reader (employees could put a finger on the reader at the start and end of work (hard to cheat) )
