Across
- 2. The extent to which information contained on one level of a set of nested DFD is also included on other levels.
- 7. That part of a decision table that lists the conditions relevant to the decision.
- 8. The lowest level of decomposition for a DFD
- 12. An interactive process of breaking the description of a system down into finer and finer detail, which creates a set of charts in which one
- 13. A DFD that is the result of a nested decompositions of a series of subprocesses from a process on a level-0 diagram.
- 15. The process of discovering discrepancies between two or more sets of DFD or discrepancies within a single DFD.
- 16. Data at rest, which, may take the for of many different physical representations
- 17. A DFD that represents a system major process, data flows, and data stores a a high level of detail.
- 18. The origin or destination of data; sometimes referred to as external entities
Down
- 1. The work or actions performed on data so that they are transformed, stored, or distributed.
- 3. An overview of an organizational system that shows the system boundary, external entities that interact with the system, and the major information flow between the entities and the system.
- 4. A picture of the movement of data between external entities and the processors and data stores within a system.
- 5. The extent to which all necessary component of a DFD has been included and fully described
- 6. A matrix representation of the logic of a decision; it specifies the possible conditions for the decision and the resulting actions.
- 9. The part of a decision table that lists the actions that result for a given sets of conditions.
- 10. In a decision table, a condition whose value does not affect which actions are taken for two or more rules.
- 11. The part of a decision table that specifies which actions are to be followed for a given set of conditions.
- 14. The conservation of inputs and outputs to a DFD process when that process is decomposed to a lower level.
