Assignment: Draw and explain a Use-Case diagram for a Library Management System. Introduction: Capturing the dynamic behaviour of a system is one the key aspects to create a model. Dynamic behaviour means the behaviour of the system under operation. Use case diagrams are used in Unified Modeling Language‚ a standard modelling language for the modeling of real-world objects and systems. A use case diagram is to explicitly define the working of a system with in a system boundary. Each system is primarily

Normalization of the ERD By: Vanessa Kennedy Normalization of the ERD The normalization of the ERD along with the driver’s log is taking all of the data within the database and putting the information into tables (World Book‚ 2011). In addition‚ after the data is normalized it then is put into an Entity Relationship Diagram or ERD (World Book‚ 2011). In this paper we will look at the ERD of the driver’s log. The normalization that I would perform on the driver’s log would be on the Driver’s

Venn diagram –Max-min 1. According to a survey‚ at least 70% of people like apples‚ at least 75% like bananas and at least 80% like cherries. What is the minimum percentage of people who like all three? Answer: Let’s first calculate the surplus: percentage of people who like apples + percentage of people who like bananas + percentage of people who like cherries = 70% + 75% + 80% = 225% = a surplus of 125%. Now this surplus can be accommodated by adding elements to either intersection of only
