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.

Logical and physical models represent the key elements and processes of the software development. The logical model describes the processes, and data, in as much detail as possible, without giving regard to how the system will be implemented. Logical data models include

b. One of the issues in denormalized data is that it can result in many-to-many

If we encounter a strange situation or concept we try and search our databases for a similar model or a least one the may roughly match. This makes the construction of the new schema easier and we can utilize some of the existing schema’s model as an aid in construction. So we access “restaurant” when we create “food

briefly outlined in table 1.0 to help visualize the relationship between the models and frameworks. The

A conceptual model need not be detailed and complex. It can be just a simple representation of relationships to be studied. For example, if a dependence relationship is proposed as research objective, then the researcher has to specify the dependent and independent concepts. For an application of an interdependence technique, the dimensions of structure or similarity should be specified. Sometimes a concept or an idea, rather than specific variables, is defined in both dependence and interdependence situations.

This document is an entity-relationship diagram, or “ERD,” for a system to manage electronic resources. An ERD is a model that identifies the concepts or entities that exist in a system and the relationships between those entities. An ERD is often used as a way to visualize a relational database: each entity represents a database table, and the relationship lines represent the keys in one table that point to specific records in related tables. ERDs may also be more abstract, not necessarily capturing every table needed within a database, but serving to diagram the major concepts

For illustrating the results of the fact finding and problem formulation we used Problem Statements matrices, Problems, Opportunities, Objectives, and Constraints Matrices etc. For the analysis and design of the new system, we used DFDs (context diagram, diagram 0), use case diagram and use case narratives, ERD and interface design. The DFDs and ERD diagram are designed using Microsoft Visio 2007, and the interfaces are designed using visual studio 2008.

When expressing the holistic approach of agile information systems applied to business, it becomes imperative that one addresses the specific framework toward the approach. Although, holistic in theory the specific framework for strategy itself must break down into independent strategies and examined as an ongoing whole. Take the company Amazon.com for example, their information system strategy combines the independent strategies of the framework however, they independently transpire and flow from one to another through a process of ever-changing information collaboration. In the year 2000, Amazon.com chose to provide this service to customers, which included a network of retailers

A conceptual management tool is a structured, model based way of proceeding to improve the problem solving or decision making process either individually or for a group in an organizational context. A conceptual tool achieves this by providing thought structures, action steps, and representation formats to facilitate convergent (analytical) or divergent (creative) thinking.

With respect to the web warehouse, schema integration is one of its important perspectives. There are heterogeneous sources of data in World Wide Web which vary in their schema configuration. Schemas from different
