Form-based lookup: When using a data entry form to perform a look-up operation for a specific record, what is the typical interaction pattern?

Difficulty: Easy

Correct Answer: you type the key in an entry line, and the correct form is displayed

Explanation:


Introduction / Context:
Forms are a common user interface for CRUD tasks (create, read, update, delete). Efficient lookup minimizes user effort and reduces errors by retrieving a specific record based on a key or search criterion rather than browsing sequentially through many records.


Given Data / Assumptions:

  • The form supports keyed search (e.g., by ID, code, or unique attribute).
  • The database backend can fetch the targeted record efficiently via index.
  • We want the standard, efficient workflow for users.


Concept / Approach:
The most efficient pattern is to enter a key (or search value) into a designated field and have the form display the matching record immediately. Sequential browsing is inefficient and error-prone. Modern form frameworks offer search boxes, combo boxes with autocomplete, or dedicated lookup dialogs to reduce friction.


Step-by-Step Solution:

Identify the presence of a key field suitable for indexed search.Enter the key and trigger the lookup (press Enter or click Search).Confirm the form loads the target record, enabling edit or view.


Verification / Alternative check:
Usability guidelines recommend direct lookup by key or unique attribute; database indexing ensures fast retrieval compared to manual paging through forms.


Why Other Options Are Wrong:

  • Enter any value without key semantics: ambiguous; key-based lookup is standard.
  • Sequentially scanning each form: inefficient and not typical of modern systems.
  • All of the above: includes inefficient behavior and is not the typical pattern.


Common Pitfalls:
Relying on manual browsing when indexes and search fields exist; not validating keys before executing the lookup.


Final Answer:
you type the key in an entry line, and the correct form is displayed
