Hi i need someone to complete my milestones 2 and 3 for me. I need them ASAP.
Part 1
Synopsis
1. Level 0 Data flow Diagram
T
he requirements analysis phase answers the question What does the user need and want from a new system? The requirements analysis phase is critical to the success of any new information system! In this milestone we need to identify what information systems requirements need to be defined from the system users perspectives.
The Data Flow Diagram (DFD) is a graphical representation of system which shows systems structure and components. The DFD shows how the data transforms in the system what the source of the input is and what is the destination. Also the DFD presents data structure and how its stored.
In this milestone you will explode the Context level DFD to Level 0 DFD to show sub-systems (processes). The Level 0 DFD shows internal data stores and how data flows through the processes.
2. Child diagram definition
C
hild level diagrams show details and are built till needed level of details is reached. First we show the information system as a single process on the Context diagram. Then we decompose and show more details until all processes are functional primitives. Not all processes are exploded to the same number of levels- its not required to explode all processes to the same level. The main target is to reach the functional primitive which will be translated into units of program code.
Objectives
After completing this milestone you should be able to:
Prerequisites
Before starting this milestone the following topics should be covered:
Process Modeling – Chapter 9
Assignment
As a systems analyst or knowledgeable end-user you must learn how to draw data flow diagrams to model business process requirements. The preliminary investigation and problem analysis phases of the methodology have been completed and you understand the current systems strengths weaknesses limitations problems opportunities and constraints. You have already built the Context models (Milestone 3) to document business requirements for the new system. You now need to build the Level 0 (System) DFD and corresponding process models.
Activities
Deliverable format and software to be used are according to your instructors specifications. Deliverables should be neatly packaged in a binder separated with a tab divider labeled Milestone 5-Part II.

Part 2
Synopsis
Each process from primitive DFD may be developed as the individual module.
The software design technique which is based on the composing software from separate interchangeable components is known as the module.
Modular design is a way to organize the complex system as a set of distinct components. Components may be developed tested independently and then plugged together.
Modular design is supported by three types of logic:
– Sequential;
– Decision making or control;
– Iteration or repetition.
Sequential execution of steps one after another.
Decision making – execution of step depends on results of condition or set of conditions. Decision making is also called the selection or control.
Iteration execution of steps is repeated until the specific condition changes. Iteration is also called as repetition or looping.
In this milestone you will write the Structured English for primitive process.
Objectives
After completing this milestone you should be able to:
Prerequisites
Before starting this milestone the following topics should be covered:
1. Child level DFD Chapter 9
2. Physical level DFD Chapter 9 and12
3. Structured English Chapter 9
4. Fact-finding results Chapter 6
Assignment
The goal of this part of project is to write Structured English.
Activities
1. Write the Structured English for one-two primitive processes. Include sequential decision making and iteration logics. Your instructor will indicate what specific processes to document.

MILESTONE 5 PROCESS MODELING – Part III (User Interface)
Synopsis
Management and users make important decisions based on system outputs. Outputs present information to system users. Outputs the most visible component of a working information system are the justification for the system. These outputs are produced from data that is either retrieved from databases or more often input by users.
Good input and output design can make the difference in whether or not an information system is used effectively. User interface design provides a roadmap or dialog that integrates the inputs and outputs.
In this milestone you will design outputs inputs and user interface for the Employee Benefits System..
Objectives
After completing this milestone you should be able to:
Design a GUI output screen and printed computer outputs.
Design a GUI input screens that use the proper screen-based controls.
Design a GUI screen that integrates the above outputs and inputs.
Prerequisites
Before starting this milestone the following topics should be covered:
1. Output design Chapter 15
2. Input design Chapter 16
3. User interface design Chapter 17
Assignment
The goal of this project is to design outputs inputs and a user interface to track employee data.
Activities
1. Design at least one of the following outputs for the Employee Benefits System: Employee participation Report Savings Bond Contribution Report United Way contribution Report and Employee Telephone Listing. Your instructor will indicate what specific outputs you are to design.
2. Design at least one of the following input screens for the Employee Benefits System: Employee Contact Info (add/update) Employee Profile (add/update) and Emergency Contact Info (add/update). Your instructor will indicate what specific inputs you are to design.
3. Design a user interface that integrates the above outputs and inputs. [Note: this requirement is for the main system screen and all subsequent screens that may be used to arrive at the screens designed for Activity 1 and 2.]
The above designs should represent prototypes (thus include sample data in your designs). To develop the prototypes use any available tool: Visio CASE tool personal DBMS (e.g. Access) or RAD tool (e.g. Visual Basic MS Visual Studio). Your instructor may indicate what specific design tool you should use.
Your instructor will specify deliverable format and software to be used. Deliverables should be neatly packaged in a binder separated with a tab divider labeled Milestone 5-Part III and accompanied with a Milestone Evaluation Sheet.
