  2. 2. Input Data Persistent Data Process Output
  3. 3. Why be concerned about INPUT DESIGN? <ul><li>Self-checking digits or check-digit </li></ul><ul><li>Completeness checks </li></ul><ul><li>Get the exact output </li></ul>Data Verification & Validation (V&V):
  4. 4. “ Input” involves 3 steps: <ul><li>Batch </li></ul><ul><li>On-Line (real-time) </li></ul><ul><li>Hybrid </li></ul>“ Input” Methods: 1. Collecting 2. Entering 3. Processing
  5. 5. <ul><li>Collecting and Entering can be done off-line. </li></ul><ul><li>Entering data can be done by trained personnel. </li></ul><ul><li>Processing can be done very quickly. </li></ul><ul><li>Processing can be done during non-peak times. </li></ul>BATCH INPUT - ADVANTAGES
  6. 6. <ul><li>Data collection usually has to be a centralized activity. </li></ul><ul><li>Data entry usually needs to be done by specially trained personnel. </li></ul><ul><li>The processing activity is delayed, hence the possibility exists for data to be considered old or untimely when it finally gets processed. </li></ul><ul><li>Since processing is usually done during off-hours, input errors detected during processing would not get corrected until the next regularly scheduled processing of input data. </li></ul><ul><li>The off-hours computer operator may have to call the systems analyst or programmer if the program malfunctions. </li></ul>BATCH INPUT - DISADVANTAGES
  7. 7. <ul><li>The data can be entered by its owners. </li></ul><ul><li>The data can be entered as close to their origination as possible. </li></ul><ul><li>Immediate feedback can usually be given regarding the correctness and acceptability of the data. </li></ul><ul><li>The input data can immediately update a database thus making it as current as possible. </li></ul>ON-LINE INPUT - ADVANTAGES
  8. 8. <ul><li>Equipment may be more costly to perform the input. </li></ul><ul><li>Users are not always well trained to input data. </li></ul><ul><li>User data entry procedural controls may be lacking. </li></ul><ul><li>Software must have additional controls to handle it. </li></ul><ul><li>Data is often only entered during business hours thus impacting the normal computer load. </li></ul><ul><li>The data entry activity could actually be slower than the equivalent batch processing for the same data. </li></ul>ON-LINE INPUT - DISADVANTAGES
  9. 9. <ul><li>Keyboard </li></ul><ul><li>Magnetic Ink Character Recognition (MICR) </li></ul><ul><li>Optical Character Recognition (OCR) </li></ul><ul><li>Optical Mark Recognition (OMR) </li></ul><ul><li>Digitizer </li></ul><ul><li>Image Scanner & Facsimile (Fax) Machines </li></ul><ul><li>Point-of-Sale Device (POS) </li></ul><ul><li>Automatic Teller Machine (ATM) </li></ul><ul><li>Mouse </li></ul><ul><li>Track Ball </li></ul><ul><li>Joystick </li></ul><ul><li>Pens </li></ul><ul><li>Scales </li></ul><ul><li>Voice Recognition </li></ul><ul><li>Touch Screen </li></ul>INPUT DEVICES
  10. 10. <ul><li>Input only necessary data </li></ul><ul><li>Let the system calculate or derive data </li></ul><ul><li>Use Business Codes where appropriate </li></ul><ul><li>Movement should be left-to-right, then top-to-bottom </li></ul>GENERAL GUIDELINES FOR INPUTING DATA
  11. 11. That’s all folks!
