Q. Structured Analysis and Design Approach?
The objective of structured system analysis and design is to reduce maintenance time as well as effort. Modeling is the act of drawing one or more graphical representations of a System. Model driven development techniques lay emphasis on the drawing of models to help visualize and analyse problems, design Information systems and define business requirements. The first model driven scheme is Structured Analysis and Design approach.
Structured Analysis is a development method for analysis of existing automated systems or manual systems, leading to development of specifications (expected behaviour orfunctionality) for proposed system. The aim of structured analysis scheme is to organize the tasks associated with requirement determination to provide a complete and accurate understanding of a current situation. The primary tasks of structured system analysis scheme are:
It is a process-centred approach which is used to model business requirements for a system. Structured analysis introduced a process-modeling tool known as the Data flow diagram used to illustrate business process requirements. With the help of DFD systems analyst can show the system overview. Data modeling tools like Entity relationship diagrams are used to explain business data requirements. With the help of ER diagram analyst can show database overview.
DRAM consists of MOSFET's but the technique is to use the drain source capacitance to hold charge. If charge is present logic '1' is held, no charge logic '0'. As you know capacito
