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

ABSTRCT Every day when you wake up and explore the world‚ you tend to notice that the world around you is changing drastically. Technology is growing faster than the growth of population in world. But not all Technology is utilized for the betterment of the life of people. One of the greatest effects of technology is its utilization in the field of robbery. People have become so greedy that they find new and unique way of robbery. But not all brains work in worked way. We have utilized our

POTENTIAL ENERGY DIAGRAM In physics the terms of mechanical energy usually refers to Potential energy (U) and Kinetic Energy (K). In the absence of non-conservative‚ or dissipative forces‚ these energies obey the law of conservation of energy‚ or ΔU + ΔK = 0. That is‚ when a system is only acting under the influence of conservative forces its total energy content never changes‚ the energy just converts between forms. At any point in the cycle‚ the total energy is constant‚ U + K = Umax = Kmax

4.6.2 Class Diagram: • In software engineering‚ a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system’s classes‚ their attributes‚ operations (or methods)‚ and the relationships among objects. • The class diagram is the main building block of object oriented modeling. • It is used both for general conceptual modeling of the systematic of the application‚ and for detailed modeling translating

USE-CASE DIAGRAM EXERCISE 1. Draw a use case diagram for an ATM machine with the following functionality. A customer’s interaction with the system involves logging in‚ making withdrawal requests‚ deposit requests‚ and balance inquiry requests. If the customer logs in‚ there is a possibility (although rare) that the system will confiscate the card (for example‚ if the login is incorrect or if the bank determines that the customer’s balance is significantly under zero). Card confiscation involves

Explain errors of omission and errors of commission. Ans - == Errors of commission == An error of commission occurs when you record an incorrect value in posting. Such errors include original entry errors‚ transposition errors‚ calculation errors and reversal of entries. An original entry error occurs when an incorrect figure is recorded and posted. A prime instance of this is the ten-key error‚ where you accidentally hit the number above the correct key. For example‚ if you enter 7‚ instead
