CIS321 Milestones 5 part 2 and 3 EBS




Hi i need someone to complete my milestones 2 and 3 for me. I need them ASAP.;;;MILESTONE 5 ? PROCESS MODELING - Part II (Exploded DFD);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 it?s 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- it?s 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;Create a Level 0 (System) Data Flow Diagram;Create a Child Data Flow Diagram;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 system?s 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.;A ctivities;Develop Level 0 DFD. Make assumptions where necessary.;Draw one Child Diagram using the Level 0 diagram.;Continue decomposition of one process up to primitive processes (Level 2, Level 3, etc.);Deliverable format and software to be used are according to your instructor?s specifications. Deliverables should be neatly packaged in a binder, separated with a tab divider labeled ?Milestone 5-Part II?.;References;? Context Data Flow Diagram Narrative ?

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;Write the Structured English for primitive process.;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.;References;Previous narratives and supplied forms;Templates;See on-line learning center website for the textbook.;Deliverables;Structured English: Due: __/__/;Time;-----------------------------------------------------------------------------------------------------------------------;;;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.;References;Previous narratives and supplied forms;Optional;Guidelines or additional technical requirements such as data dictionary.;Templates;See on-line learning center website for the textbook.;Deliverables;Input Design Form: Due: __/__/;Time;Output Design Form: Due: __/__/;Time;User Interface Form: Due: __/__/;Time;Milestone?s Point Value
