Tutorial Week 7 - Class and Entity-Relationship Diagrams 1 Class Diagrams and Entity Relationship Diagrams (ERD) Class diagrams and ERDs both model the structure of a system. Class diagrams represent the dynamic aspects of a system: both the structural and behavioural features. ERDs‚ depicting only structural features provide a static view of the system. 2 Class Diagrams 2.1 Elements of a class diagram: 2.1.1 class A class is a general concept (represented as a square box). A class defines

4.3 DATA FLOW DIAGRAM A data flow diagram is a graphical technique that depicts information flow and transforms that are applied as data move from input to output. The DFD is also known as Data Flow Graph or Bubble Chart. The DFD is used to represent increasing information flow and functional details. Also DFD can be stated as the starting point of the design phase that functionally decomposes the requirements specifications down to the lowest level of detail. A Level 0 also called a fundamental

Two Headed weaver Once upon a time‚ there was a weaver by the name Mantharaka. One day when he was weaving the cloth‚ the wooden frames of his loom broke. He took an axe and went to the forest to bring wood in order to make new frames. He went round the forest but didn’t find the adequate wood for the frames. From the forest‚ he drifted towards the seashore where he saw a huge tree. He thought that if he could cut wood from the tree‚ he would have enough wood for all frames and would stay throughout

Free Data Flow Diagrams Tutorial DFD Tutorial Data Flow Diagrams - Introduction Data flow diagrams can be used to provide a clear representation of any business function. The technique starts with an overall picture of the business and continues by analyzing each of the functional areas of interest. This analysis can be carried out to precisely the level of detail required. The technique exploits a method called top-down expansion to conduct the analysis in a targeted way. [pic] The

Models of communication Main article: Models of communication The studies on information theory by Claude Elwood Shannon‚ Warren Weaver and others‚ prompted research on new models of communication from other scientific perspectives like psychology and sociology. In science‚ a model is a structure that represents a theory.[5] Scholars from disciplines different to mathematics and engineer began to take distance from the Shannon and Weaver models as a ’transmissible model’: They developed a model

TYPES OF DATA FLOW DIAGRAM: LOGICAL DFD PHYSICAL DFD Data Flow Diagrams (DFDs) are categorized as either logical or physical. A logical DFD focuses on the business and how the business operates. It describes the business events that take place and the data required and produced by each event. On the other hand‚ a physical DFD shows how the system will be implemented. Design Feature Logical Physical What the model depicts How the business operates How the system will be implemented

CHAPTER 4 HARDWARE DESCRIPTION 4.0 Arduino: The Arduino Uno is a microcontroller based on the ATmega328. It has 14 digital input/output pins in which 6 can be used as PWM‚ 6 analog inputs‚ a 16 MHz ceramic resonator‚ a USB port‚ a power jack‚ an ICSP header‚ and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.[11] The Uno differs from all preceding boards in
