Systems Analysis - Logical Design

We focus on the business problem, independent of technology in the phases and activities of system analysis.
  1. the survey and planning of the system and project
  2. the study and analysis of the existing business and information system
  3. the definition of business requirements and priorities for a new or improved system
bulletPrototyping 
  1. Feasibility Prototyping
  2. Requirements Prototyping
bulletRAD - Rapid Application Development for Prototyping
bulletJAD - Joint Application Development emphasizes participative development among business analysts, system architects, software engineers and users for Joint Requirements Planning and Joint Application Design.
bulletModern Structured Analysis - a process-centered technique to model business requirements for the systems.
  1. Process Modeling - Data Flow Diagram
  2. Interface Modeling - Context Diagram
  3. Network Modeling - Decomposition Diagram and Location Connectivity Diagram
bulletInformation Engineering - a data-centered, but process-sensitive technique that is applied to the organization as a whole or a significant part, such as a division, rather than on an ad-hoc, project-to-project basis as in Modern Structured Analysis.
  1. Information Strategy Planning - applies systems analysis methods to examine the business as a whole to define an overall plan and architecture for subsequent information systems development.
  2. Business Area Analysis - uses systems analysis methods to study the business area and define the business requirements for a highly streamlined and integrated set of information systems and computer applications to support that business area.
  3. Other System Analysis and Design Methods - include some combination of structured analysis and design, prototyping, and object-oriented analysis and design.

          1.  Data Modeling - Entity Relationship Diagram (ERD)

          2.  Process Modeling

bulletObject-Oriented Analysis - We utilized this technique to study existing objects to see if they can be reused or adapted for new uses and define new or modified objects that will be combined with existing objects into a useful business computing application.
  1. Our Object-Oriented approach is centered around Object Modeling - UML (Use Case Vs. Class Diagram)
  2. We apply Object-Oriented Principles to the Object-Oriented analysis        

          1.  Inheritance - methods and/or attributes defined in an object class can be inherited or reused by another object class.

          2.  Polymorphism - the same named behavior may be completed differently for different objects/classes.

          3.  Encapsulation - the packaging of several items together into one unit.

bulletFAST System Analysis - We integrate all the popular techniques in FAST System Analysis: Structured Analysis via process modeling, Information Engineering via data modeling, Prototyping via Rapid Application Development, Joint Application Development for all methods, and Object-Oriented Design.
