Design and Implementation of Real-Time Processing In Accounting Information System.
ABSTRACT
This research work empirically synthesizes the design and implementation of real time processing in accounting information system.
Real-time processing is an e-business term used to describe the situation whereby a user sends in transactions and awaits a response from a distant computer before continuing.
Response time on the data communications facility is crucial when a customer is utilizing a voice call to obtain information requiring a quick response, i.e. booking an airline flight or obtaining stock details.
In a real time processing, there is a continual input, process and output of data. Data has to be processed in a small stipulated time period (real time), otherwise it will create problems for the system.

INTRODUCTION
This is an extract from the work of renowned researchers, practitioners and expert in the field of real-time system. Their works are grouped into six parts, together encompassing twenty chapters.
Each part is devoted to a mainstream subject, the chapters therein developing one of the major aspects of real-time system theory, modeling, design, and practical applications.
Starting with a general approach in the area of formalization of real-time systems, and setting the foundations for a general systemic theory of those systems, the book covers everything from building modeling frameworks for various types of real-time systems, to verification, and synthesis.
