  1. Question : (TCO 5)Some systems developers believe that a data model is the most important part of the statement of information system requirements because
  • the characteristics of data captured during data modeling are crucial in the design of databases, programs, computer screens, and printed reports.
  • data rather than processes are the most complex aspects of many modern information systems and thus require a central role in structuring system requirements.
  • the characteristics about data are reasonably permanent.
  • structural information about data is essential to generate programs automatically.
  • All of the above

Question 2. Question : (TCO 5) A detailed, logical, and graphical representation of the entities, associations, and data elements for an organization or business area best describes a(n)

  • logic model.
  • data-flow diagram.
  • entity-relationship diagram or E-R diagram.
  • structure chart.
  • data tree.

Question 3. Question : (TCO 5) A collection of entities that share common properties or characteristics best defines

  • entity type.
  • entity instance.
  • entity occurrence.
  • entity collection.
  • data set.

Question 4. Question : (TCO 5) An attribute (or combination of attributes) that uniquely identifies each instance of an entity type defines

  • data element occurrence.
  • trigger.
  • candidate key.
  • associative entity.
  • data marker.

Question 5. Question : (TCO 5) A relationship between the instances of one entity type is a(n)

  • unary relationship.

  • requirements structuring step of the analysis phase.
  • alternative generation and selection step of the analysis phase.
  • testing step of the implementation and operation phase.
  • project initiation and planning step of the planning and selection phase.
  • designing the human interface step of the design phase.

Question 9. Question : (TCO 6) Enumerating different potential implementation environments that could be used to deliver the different sets of capabilities occurs during the

  • requirements structuring step of the analysis phase.
  • alternative generation and selection step of the analysis phase.
  • testing step of the implementation and operation phase.
  • project initiation and planning step of the planning and selection phase.
  • designing the human interface step of the design phase.

Question 10. Question : (TCO 6) Constraints on systems development may include such factors as

  • available financial and human resources.
  • elements of the current system that cannot change.
