Application Of A Solid Foundation

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

Understanding the business model of enterprise and identifying the entities of that model is the first step in setting up database. Requirements analysis includes tasks of determining the needs or conditions to meet. Requirement specification document will be generated at the end of this step.

Process Model: Process Model is a flow chart of a business that explains the process stages involved in the production of goods and services. When planning, any project system diagram is significant. This will admit displaying the organizations view about their facts and whether or not they will solve the design problem.

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

This model demonstrates the data attributes logical entities and relationships between these entities within a business function. It also helps to create the physical data model. Moreover, it shows more details while integrate business logic and business rules. This model is used to describe the domain concept and their relationship of the domain problem.

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 database. You will create two conceptual models.

Provides UML modelling for database designs, with the ability to represent the integration of data and application requirements through logical and physical designs

From the list of entities and discussion of relationships create a fully-attributed Entity Relationship Diagram (ERD) to model the functional requirements of the Tarleton Gaming Solutions database. Because your client’s background in database design is quite limited provide a detailed explanation and justification of the ERD you are proposing. This includes but is not limited to the choice of entities, attributes, primary and foreign keys, relationships, and cardinality.

The next step in the database development effort is to select one process or a set of related processes for further analysis and improvement

A logical data model describes the data in as much detail as possible without concern how they will be physical implemented in the database.in data warehousing it is common for conceptual data model and the logical data model to be combined into a single step . Also translating conceptual data models into a format consistent with the architure used by the data management software to be used with the application. Logical data a model is the same for all data management technologies, while logical data model for one real-life scenario in generic, physical data model will depend upon a particular implementation.

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).

The systems development process can follow any number of methods, tools, and approaches and is not tied down to any specific one. Although there are some conventions, changes and additions can be arbitrarily adapted to suit the customized process.

Through the use of (DFDs), which emphasize the logic underlying the system, the systems analysts can put together a graphical representation of data movement through the organization.

The Logical view of the system describes the functional requirements of the system i.e. what the system should provide in terms of services to its users [2]. The Logical Architecture is described with the help of class diagrams statechart diagrams. This view has a Main Diagram by default. Additional diagrams can be added through out the analysis and design process. [7]
