Input Forms Content and Organization

• Need for forms
• Event analysis and forms
• Relationship between input forms and tables
• Types of input forms
• Single-record entry form
• Tabular entry forms
• Multi-table entry forms

Input Forms Content and Organization

• Means of data entry
• 4 ways to enter data
• 1. Internal agent types in the data
• 2. Internal agent selects data to be entered
  using a look-up table, radio button, or check box
• 3. Internal agent scans the bar code of a product
  or the identification card of a customer
• 4. User enters the data using a form at the
  companys Web site

Input Forms Content and Organization

• Identifying forms required
• The need depends on
• What data need to be collected and
• How the data will be collected
• A UML use case is a sequence of steps
• A use case diagram is a graphical presentation
  providing a list of use cases that occur in an
  application
• CRUD framework a tool used as an aid in
  developing use case diagrams

Input Forms Content and Organization

• Documenting form content and organization - form
  design template
• Attributes recorded in tables
• Attributes displayed from tables
• Calculated fields
• Foreign keys
• Queries

Interaction with Forms Controlling AIS Inputs

• Form interface elements
• Text boxes
• Labels
• Look-up feature
• Command buttons
• Radio buttons
• Check boxes

Interaction with Forms Controlling AIS Inputs

• Improving accuracy and efficiency of data entry
• Primary key
• Look-up feature
• Scanning
• Record-checking
• Confirmation
• Referential integrity
• Format checks
• Validation rules

Interaction with Forms Controlling AIS Inputs

• Improving accuracy and efficiency of data entry
• Defaults
• Application-level default
• Agent-level default
• Transaction-level default
• Prohibit blank fields
• Computer-generated values
• Prompt user to accept/reject data

9
Interaction with Forms Controlling AIS Inputs

• Input controls and workflow controls
• Key difference
• Input controls refer to checks performed
  automatically by the computer itself
