2. using the data requirements and the business rules provided, develop a conceptual model (ERD), including attribute data types and required field lengths; and

The Verification and Validation, or V-model, Software Development Paradigm will be used to define the development life cycle of the software product. This paradigm was chosen because it allows us to test the software during each stage of the project in an inverse way. Also, because the validation and verification of

As the information system is designed, implementation decisions describing how the system will work are made. Data flow diagrams offer those implementation details, including data stores that refer to files and database tables, programs and human actions that perform processes. The automated parts of the system are differentiated from the manual parts by the human-machine boundary (Dennis, Wixom,

A. Lab # : BSBA BIS245A-1 B. Lab 1 of 7 : Introduction to MS Visio and MS Access C. Lab Overview--Scenario/Summary TCOs: 1. Given a business situation in which managers require information from a database, determine, analyze and classify that information so that reports can be designed to meet the requirements. 2. Given a situation containing entities, business rules, and data requirements, create the conceptual model of the database using a database modeling tool. Scenario: You have been asked to create two conceptual database models using MS Visio Database Model Diagram Template. The purpose of this lab is to have you gain familiarity with the various modeling tools needed to create a conceptual model (entity relationship diagram) of a

One of the first steps involved in carrying out a preliminary investigation include understanding the problem or opportunity in sight. The analyst must first identify which department, users and business processes the system request is involved in to evaluate and assess the causes and effects related in the proposed system. Defining the project scope and constraints is the second step. With clear indications of the projects boundaries or extent the project scope is determined, while the requirements or conditions the system must confer to or achieve determine the projects constraints. The third step in a preliminary investigation consists of fact finding techniques, that involve the analyses of charts, interviews with users, managers and review of documents , observing operations and finally user surveys. Followed by the fourth step that includes the process of evaluating feasibility. This step consists of evaluating the feasibility of the proposed projects operational, technical, economical and

The following analysis document provides an entity relationship (E-R) diagrams in support of a car-insurance company requirements as detailed in the assignment statement.

Data Flow Modelling – This is the process of modelling and recording how data flows around a system. A Data Flow Model is made up of connected Data Flow Diagrams (DFD) which are supported by appropriate documentation. DFDs represent the processes and functions within a system (activates that transform data from one form to another), data stores (file storage, external entities (things that send data into a system or receive data from a system) and finally data flows (show the flow of data around the system).

Purpose of this assignment: To demonstrate understanding of principles of software design, in relation to specific programming scenarios, and how these principles relate to the software development life cycle.

This tool provides graphical process and makes a better understanding of the business information. It also helps to reduce the time to document business processes, reduce costs, and increase customer satisfaction.

System development can generally be thought of having two major components: systems analysis and systems design. In System Analysis more emphasis is given to understanding the details of an existing system or a proposed one and then deciding whether the proposed system is desirable or not and whether the existing system needs improvements. Thus, system analysis is the process of investigating a system, identifying problems, and using the information to recommend improvements to the system. System design is the process of planning a new business system or one to replace or complement an existing system.

Though many people interchange system engineering models and software engineering life cycle models, they are defined as two different approaches to software development. System engineering is the technical and technical management process that results in delivered products and systems that exhibit the best balance of cost and performance. As the program progresses from one phase to the next one, so does the system engineering process. It deals with the overall management of engineering project during their life cycle. Its main focus is knowing what the clients and end users wants and needs are satisfied and developing just that all the way through the system’s entire life cycle. Whereas, on the other hand, software engineering focuses on the quality of the product or system, how cost effective it is, is it done within the time-constraints given, whether it is easy to maintain and enhance, and does it work as the requirements defined. Its main focus is on delivering a product that meets the requirement specifications. There are so many models to choose from, as it all depends on what the project needs and entails. Depending on the requirements, allows for the choice of what mode to use.

The interview session has been done by include an open-ended and closed-ended question which are related to the implemented project. Next, sampling technique is executed by system analyst who does evaluation to the current system or prototype. These processes give feedback in evaluation form that filled after tested the system. Lastly, observation is performed by using questionnaire form. According to Burch (1992), the questionnaire is analyzed and transform into structured form that easy to understand. After all information has been collected, structuring of system requirement takes place. It focused on development process modeling which perform “graphically representing the process, or actions, that capture, manipulate, store, and distribute data between a system and environment” (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is structured by system analyst using special tools and techniques to create a decision table. According to Hoffer, George and Valacich (2012), decision table is a “diagram of process logic where the logic is reasonably complicated” (p. 200). This table is useful to help system analyst to make a decision toward the project. Then all information’s gained from this phase are documented in System Analysis Report (SAR) that acts as a guideline or reference to the future system development project (Burch, 1992).
