New file and form 2

  1. 1. Design is the process of developing specificationfor a candidate system that meet the criteriaestablished in system analysis.
  2. 2. 1.INPUT DESIGNIt is the process of converting user oriented inputsto a computer based format.CLASSIFICATION OF INPUT DESIGNA)Input dataThe goal of designing input data is to make dataentry as easy, logical, and free from errors aspossible.
  3. 3. •ContdIn entering date, operators need to know thefollowing:1.The allocated space for each field.2.Field sequence , which must match that in thesource document.3.The format in which data field are entered : For example, filing out the data field isrequired through the edited format mm/dd/yy .
  4. 4. Source documentA source document should be logical and easy tounderstand. Each area in the form should be clearlyidentified.For example a field as simple as date of birth may bewritten in four different ways:1.19 September 19352.Sept. 19,19353.9/19/354.19/9/35
  5. 5. Source data are input into the system in a varietyof ways:•Punch cards•Key-to-diskette•MICR•Mark-sensing readers•Optical character recognition•Optical bar code readers
  6. 6. 1.Computer output is the most important and direct sourceof information to the user.2.Efficient ,intelligible output design should improve thesystem ‘s relationship with the user and help in decisionmaking.The following media devices for computer output:1.Micr readers2.Line ,matrix and daisy wheel printers3.Computer output microfilm(COM)4.CRT screen display
  7. 7. The standards for printed output suggest thefollowing• Give each output a specific name or title• Provide a sample of the output layout, including areaswhere printing may appear and the location of eachfield.• State whether each output field is to include significantzero ,spaces between fields, and alphabetic or an otherdata• Specify the procedure for proving the accuracy ofoutput data
  8. 8. WHAT IS A FORM?Form is a business document that contain somepredefined data and may include some areawhere additional data is to be filled.It is a tool that carries data and information.
  9. 9. 1. Flat formA flat form is single copy form prepared manually orby machine and printed on any grade of paper.It is the easiest form of design , print, and reproduceIt has the low volume used , andIt is least expensive

  11. 11. 2. Snap out formsThese forms have an original copy and several copies with one-time carbon paper interleaved between them.
  12. 12. 3. Fanfold formsThese are multiple –unit forms joined together in a continuousstrip with perforation between each pair of forms.
  13. 13. The process of designing forms includes: •User-focused activity •Follows a prototyping approach •Requirements determinationCopyright © Amity University 14
  14. 14. A business document that contains only predefined data. In this we can‘t include any additional information. This is a passive document for reading or viewing data. A report generally contains data from many database records or transactions unlike form which based on one database record.Copyright © Amity University
  15. 15. Scheduled: produced at predefined time intervals for routineinformation needsKey-indicator: provides summary of critical information onregular basisException: highlights data outside of normal operating rangesDrill-down: provides details behind summary of key-indicatoror exception reportsAd-hoc: responds to unplanned requests for non-routineinformation needs   
  16. 16. Meaningful titles: It use clear, specific, version information, and current data Meaningful information: It include only necessary information, with no need to modify Balanced layout: It use adequate spacing, margins, and clear label.Copyright © Amity University 17
  17. 17.   Case: mixed upper and lower case, use conventional punctuation Spacing: double spacing if possible, otherwise blank lines between paragraphs Justification: left justify text, ragged right margins Hyphenation: no hyphenated words between lines Abbreviations: only when widely understood and significantly shorter than full textCopyright © Amity University
  18. 18. RULES AND CAPTIONIn designing form ,use rules(lines) to guide the human eye toread and write data groups.It specifies what information to write in the space provided.Rules can used to make boxes in which the user placed data.Caption tells the user what information goes in the particularposition.
  19. 19. BOX DESIGNWhile designing a form its easy to form box style rule , withcaptions in the upper left corner.Forming box design reduces the form size by 25 to 40 percent.SPACING REQUIREMENTSpacing requirement basically tells the space should be providedaccording to the information the form asked.
  20. 20. BALLOT BOX AND CHECK-OFF DESIGNUsing ballot or check-off questions that can beanswered or no can generally reduce the amount ofrequired writing.The user preference simply by checking off the desiredbox.
  21. 21. A well designed form with clearly stated caption should be selfinstructing.A sample of the instruction as follows:Date: fill in the current dateName: print the legal name in fullDescription: give title of each partSignature: your supervisor must sign here
  22. 22. Forms may be printed on paper of different colors, grades, andweight.Paper weight is based on a ream of 500 sheets that are 17 by22 inchesThree major factors to consider in paper selection:1.The number of times the form will be handled .2.The count of folding it will receive,3.The extent of exposure to the environment.
  23. 23. It basically tells that how much cost shouldincurred while making a actual form or printedform.The cost like:•Ink•Machine•Labor•Paper
