Data Processing as a Business
Need
 Electronic data processing is
  growing because it is
  capable of handling a vast
  amount of data efficiently
  and accurately.
Demands of Modern Business

   Number of transactions
   Cost
   Accuracy
   Speed
   Selectivity
   Information
   Record Keeping
   Service
   Mechanization
Number of Transactions

   Number of transactions increase
    with the growth in the size of
    business.
   Computer, with its high speed
    and capacity can process
    thousands of records.
   Computer processes records
    better than any previous method.
Cost
   Competitive pressure has made
    it essential for companies to
    adopt computerized data
    processing.
   Large number of transactions
    increase labour cost and hence
    electronic data processing is
    more feasible.
Accuracy
   Businesses      require    great
    accuracy in many areas.
   Calculations must be performed
    accurately and an error of
    fractions can create a great
    problem.
   Electronic   data     processing
    performs      thousands       of
    calculations with virtually no
    errors.
Speed

   Pace of modern business is fast.
   Decisions must be taken on
    short notices.
   Computer can process at a
    speed unequalled by any other
    means.
Selectivity

   Business       people    demand
    selectivity in the way data is
    reported.
   Manually, it is hard to present
    the data in different ways.
   Computers can display the
    same data in different ways and
    angles.
Information

   Good      decision-making    is
    essential for success of a
    business.
   Computer generates information
    precisely and quickly.
Record Keeping

   Computers can keep large
    amounts of records.
   It takes large space to store the
    records manually. Computers
    can store large number of
    records for long times
Service

   It is difficult to provide customer
    service manually.
   Computerized customer service has
    become extremely popular because
    of its speed and efficiency.
