1 of 7: Introduction to MS Visio and MS Access Scenario/Summary: 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. You will then open an existing Access database to explore database objects and to experiment with simple

Extensible Markup Language (XML) The similarities that I found are that Peter Chen’s‚ Information Engineering‚ and UML diagrams all use square cornered shapes for entities. Also that only Information Engineering diagram‚ ORM‚ UML‚ Richard Barker’s notation‚ and Peter Chen’s diagram contain the entity’s name in the shape

” 2.0 Explanation of Use Case Diagram Use case diagram is graphic description of the communication and interactions among the elements of a system. As mentioned before‚ use case is a methodology used in system to identify‚ clarify and organize system requirements. UML (Unified Modeling Language) is a standard notation for the modeling of real-world objects and systems and is been employed in use case diagram. There are 4 components contained in use case diagram‚ there are: • Boundary: Define the
