Data flow diagram (DFD) - |
(Software Engineering) a modeling notation that represents a functional decomposition of a system |
Data modeling - |
(Software Engineering) an analysis method that models data objects and their relationships |
Data objects - |
(Software Engineering) an input or output that is user visible |
Data warehouse - |
(Software Engineering) a large, independent database that has access to databases that serve many different applications that are required by a business |
Debugging - |
(Software Engineering) the activity associated with finding and correcting an error or defect - a lack of conformance to requirements found in the software after delivery to the customer |
Defect amplification - |
(Software Engineering) when a defect is introduced early in the software process and remains undetected, it often is amplified into multiple defects later in the software process |
Defect removal efficiency (DRE) - |
(Software Engineering) a nondimension ratio (between 0 and 1) that provides an indication of the degree to which errors are removed from software before it is released to end-users |
Design - |
(Software Engineering) an activity that translates the requirements model into a more detailed model that is the guide to implementation of the software |
Design specification - |
(Software Engineering) a document that describes the design |
Design walkthrough - |
(Software Engineering) a formal technical review of the design |
