 Last topic of the chapter
 Computer Based Accounting Systems
 Batch systems
 Real time Systems
 Secondary Storage

4.  How many types of computerized AIS we had
studied in Chapteer1?
 Three
 What are there names?
 Turnkey (fully tested)
 Vender supported (fully customized)
 Backbone (in between fully tested --
customizable)

5.  Group
 Continuous
 Collection
 Batch processing permits the efficient
management of a large volume of
transactions.
 A batch is a group of similar transactions
(such as sales orders) that are accumulated
over time and then processed together.
 Payroll processing is an example of a typical
batch system

6.  Two Benefits
 Efficient allocation of resources:
 By grouping similar transaction and allocating
processing resources saves our cost and time
 One can make an efficient allocation, cost
effective and specialized procedures to deal
with these batches.
 Batch processing is an economical and high-
volume transaction processing method.

7.  Better Control over the transaction process
 The accuracy of the process can be
established by periodically reconciling the
batch against the control figure.
 For example, total value of a batch of sales
orders is $100,000.
 This number can be recorded when the
batch is first assembled and then
recalculated at various points during its
processing.

8.  Large batches will surely reduce the cost of
processing for a single transaction
 Is there any allegation on this?
 Yes
 Finding an error in a very large batch may
prove difficult. When a batch is small, error
identification is much easier.?
 What is Solution and who is responsible?

9.  Real-time systems process transactions
separately as they occur
 No grouping means “no time interval”
between occurrence and recording.
 An example of real-time processing is an
airline reservations system, which processes
requests for services from one traveler at a
time while he or she waits.
 improved productivity and enhanced
customer satisfaction.

11.  Explain computer Based Accounting system,
its types, characteristics and benefits and
disadvantages.
 Which is a better computer based system?
 What are different alternatives to Computer
Based accounting systems?
