Both Class Diagrams and Use Case Diagrams are used in the requirements determination of object oriented development. Object oriented development is an approach to system development that uses the object as the basic unit of systems analysis and design. Use case shows the relationships among actors and use cases within a system. Class diagrams are widely used to describe the types of objects in a system and their relationships The purpose of Use case diagram is that it shows the interaction

Jarboe I February 8‚ 2011 Logical Fallacies Before we can understand what a logical fallacy is‚ we establish some common background information for the purposes of accurate communication. There are two types of reasoning‚ inductive and deductive. The primary difference between the two is that inductive reasoning automatically allows for an appeal to probability‚ the assumption that what could happen will happen‚ while deductive reasoning considers this a logical fallacy. Thus for the purposes

FISHBONE DIAGRAM The cause-and-effect diagram was initially developed by Japanese quality expert Professor Kaoru Ishikawa. In fact‚ these diagrams are often called Ishikawa diagrams; they are also called fishbone charts for reasons that will become obvious when we look at an example. Cause-and-effect diagrams are usually constructed by a quality team. For example‚ the team might consist of service designers‚ production workers‚ inspectors‚ supervisors‚ quality engineers‚ managers‚ sales representatives

Entity-Relationship Diagrams (ERD) Data models are tools used in analysis to describe the data requirements and assumptions in the system from a top-down perspective. They also set the stage for the design of databases later on in the SDLC. There are three basic elements in ER models: Entities are the "things" about which we seek information. Attributes are the data we collect about the entities. Relationships provide the structure needed to draw information from multiple entities. Generally

PI and ID Flowchart and Narrative The following information provides two flow charts and then a comparison of the information. These charts are performance improvement flow and the ADDIE model. Image 1 - Performance Improvement flow Image 2 – ADDIE model After reviewing both flows you can see that there are strong similarities. Both models require that analysis be completed first‚ this is important as the gap‚ need‚ or desire outcome must be determined. Using past data can show areas

Weathering Process Physical Weathering Processes Freeze Thaw (Frost Shattering) Temperatures need to fluctuate above and below freezing. When the temperature drops below 0 degrees‚ water collected in rock cracks freezes and expands. When temperatures rise again the ice melts. Pressure created by expansion results in progressive weakening of the rock. At high altitudes frost-shattered material forms scree slopes. Heating & Cooling Thermal expansion & contraction of rock in response

2. A medium-sized engineering firm has three separate engineering offices. In each office‚ a local LAN supports all the engineers in that office. Due to the requirement for collaboration among the offices‚ all the computers should be able to view and update the data from any of the three offices. In other words‚ the data storage server within each LAN should be accessible to all computers‚ no matter where they are located. Draw a network diagram that will support this configuration. 3.

Logical Fallacies Logical fallacies have existed since the dawn of time. As defined by Bassham et al a logical fallacy "is an argument that contains a mistake in reasoning." With this definition one must keep in mind that the definition of an argument according to Bassham et al is "a claim put forward and defended by reasons." The ability to recognize logical fallacy will enable one to break down an argument. This ability is crucial to the critical thinking process. Logical fallacies can

Also known as logical empiricism‚ rational empiricism or neo-positivism‚ logical positivism is the name given in 1931 by A.E Blumberg and Herbert Feigl to a set of philosophical ideas put forward by the Vienna Circle. This Vienna Circle was a group of early twentieth century philosophers who sought to re-conceptualize empiricism by means of their interpretation of then recent advances in the physical and formal sciences. Hence‚ the Vienna Circle represented a radical “anti-metaphysical” stance which
