2.3 CASE tools can help developers create computer software quickly and reliably.
2.4 Adding staff to a project to shorten the project’s length is usually a wise move, because adding staff normally translates into increased productivity.
2.5 In the development phase of the SDLC, programmers either create software from scratch or purchase commercially available software.
2.6 During the needs analysis phase, developers must determine what issues exist with the current system, then decide whether to proceed with development.
2.7 In a data flow diagram, arrows are used to represent data stores.
2.8 The system development lifecycle defines the temporal, causal and I/O relationships among the processes of the organization learned.
2.9 Participants at a Joint Application Development (JAD) workshop meeting identify system requirements.
2.10 An entity in an ER diagram is basically the identical as an entity in a DFD, the only difference being that in the former it stores data and in the latter it processes data.
