the engine room of stage 1 because it is where other techniques are used to thoroughly examine update and inquiry processing

the engine room of SSADM and the part where we enhance the data model and where real change occurs where bottom level processes are merged into functions.

Detailed explanation-1: -Stage 3 – Requirements specification This is probably the most complex stage in SSADM. Using the requirements developed in stage 1 and working within the framework of the selected business option, the analyst must develop a full logical specification of what the new system must do.
Detailed explanation-2: -Data Flow Modeling examines processes (activities that transform data from one form to another), data stores (the holding areas for data), external entities (what sends data into a system or receives data from a system), and data flows (routes by which data can flow).
Detailed explanation-3: -SSADM (Structured Systems Analysis and Design Method) is a widely used computer application development method in the United Kingdom, where its use is often specified as a requirement for government computing projects. SSADM is in the public domain and is formally specified in British Standard BS7738.
Detailed explanation-4: -SSADM combines three methods, complementing each other within a systems development cycle: Logical Data Modelling, Data Flow Modelling, Entity Event Modelling. Its main benefits are: Improvement of quality, detailed documentation of the development stages, and reusability for similar projects that follow.
