System Specifications: Formalize the design of an application’s user interface methods and products, database structures, and processing and control procedures. Therefore, systems designers will frequently develop hardware, software, network, data and personnel specifications for a proposed system. Systems analysts work with you so they can use your knowledge of your own work activities and their knowledge of computer bases systems to specify the design of a new of improved information system.
The final system design must specify what types of hardware resources (machines and media), software resources (programs and procedure), network resources ( communications media and networks), and [people resources (end users and information systems staff) will be needed. It must specify how such resources will convert data resources (stores in files and databases they design) into information products (displays, responses, reports, and documents). These specification are the final product of the systems design stage.
o
User Interface Specifications
Use handheld optical scanning wands to automatically capture product
data on bar-coded tags. Use data entry screens with key data highlighted for
better readability.
|
o
Database Specifications
Develop databases that use a relational structure to organize access
to all necessary customers and merchandise data.
|
o
Software Specifications
Develop or acquire a sales processing program that can accept entry
of optically scanned bar codes, retried necessary [product data, and compute
sales amounts In less than one second. Acquire a rational database management
package to manage stores databases.

o
Hardware and Network
Specifications
Install POS terminals at each checkout station connected to a system
of network station connected to a system of networked micro computers in each
store that are also connected to the corporate headquarters network.
