Structured System Analysis And Design

SSADM (Structured Systems Analysis and Design Method) is the government's standard method for systems analysis. This book describes the structural framework and techniques of SSADM, its application in an organization, and the way in which it relates to current issues faced by systems developers.

This text integrates traditional methodologies with modern technology. An update of the classic material on structured analysis.

Virtual presence of Internet and availability of infor-mation on the net have led to information systems becoming an inseparable part of organizations. Today, computer-based information systems are extensively used for acquisition, storage, and dissemination of data throughout the organizations. These information systems, however, need to be backed by sound software development activities. The systems analysts play a key role in development and implementation of the information systems in the organizations. It is, therefore, essential that they remain abreast of the latest software development methods and tools while using them. This concise book presents in an abstracted form, the essentials of theory and practice of structured systems analysis and design. It is aimed at getting the concep-tual framework across to the readers and thus aiding in concept implementation. Well-suited for teaching an academic course of one semester in systems analysis and design, the text is also suitable for conducting short term training programmes for software professionals. Armed with these concepts and ideas, the systems analysts will be able to tackle various aspects of systems analysis and design in real life situations.

This treatment of structured techniques in systems development is based on the author's actual project management experience. The author helps readers make a clear distinction between logical and physical systems, showing how the logical system is completely developed before the physical system starts. The presentation is descriptive and fairly elementary, requiring only some programming experience in a high-level language such as COBOL, FORTRAN or PASCAL. Topics covered include computer-based information systems, structured analysis, structured design, structured implementation, and contemporary issues in system development. The book contains many case studies.

This book describes the data flow diagram approach, which is considered to be the most popular method available for system analysis and design. This method is useful for the development of systems on micro as well as on mini/mainframe computers. It wiil also prove to be a useful book to those who wish to develop computerised systems for business applications using the data flow approach.

Presents system and program design as a disciplined science.
