Question 1 Characteristics of bad systems To be useful‚ the information system must possess the characteristic of reliability‚ relevance‚ understandability‚ complete‚ accurate and comparability. However‚ in order for Encik Khalid to detect problems occur with the current or new system are based on the characteristics of bad system which are unreliable‚ irrelevance‚ not understandable‚ incomplete‚ inaccurate‚ and incomparable. The first characteristic is unreliable. Encik Khalid may detect the

14‚2012 1. What is set? Answer: A set in mathematics is a collection of well defined and distinct objects‚ considered as an object in its own right. Sets are one of the most fundamental concepts in mathematics. Developed at the end of the 19th century‚ set theory is now a ubiquitous part of mathematics‚ and can be used as a foundation from which nearly all of mathematics can be derived. In mathematics education‚ elementary topics such as Venn diagrams are taught at a young age‚ while more

Entity Relationship Diagram - ERD Database – is a large data repository that stores a shared collection of logically data. A database can be modeled as: A collection of entities and relationship among entities. What is Entity Relationship Diagram? An entity-relationship (ER) diagram is a specialized graphic diagram that illustrates the relationships between entities in a database‚ simply it illustrates the logical structure of databases. ER diagrams often use symbols to represent different types

Reading Response (Diagrams Matter by Stan Allen) “A diagram architecture is not necessary an architecture produced through diagrams.... Instead‚ diagram architecture is an architecture that behaves like a diagram‚ indifferent to the specific means of its realization." (Par. 13) This paragraph points out the answer that beginners architecture students struggled to find. In the process of design‚ I try to find the potential through the translation from reality to the abstract diagram. While I wonder

Before starting this homework assignment‚ please review the AIB simulation in this week’s Lecture. This simulation will provide you with an understanding of how to create a network diagram‚ and how to do a forward and backward pass to determine the ES‚ LS‚ EF‚ LF and slack (float). You will also learn how to determine the duration of the project‚ and the critical path. In this homework assignment‚ you will be working through four Activity In Box (AIB) problems. Using the activity‚ duration‚ and

Research Question My research question proposed is: Does the amount of education one receives impact the individual’s participation in elections? Theory The Political Participation Theory: As education increases‚ the amount of civic responsibility an individual participates in‚ such as voting in elections‚ increases. Hypothesis Individuals who go to universities and other higher education institutions are more likely to vote in elections on a regular basis than individuals who have not

The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but

Fishbone Diagram Part 1 Individual Project Fishbone diagram allows Hotel Escargo to turn the problem upside down working through the roots so that the issue is fixed. It is also easier to fix the smaller problems that lead to the main problem. Looking at the check-in delays‚ there are a lot of small issues that have led to this occurrence. The first issue is computer malfunctions. Often times‚ computers tend to freeze due to glitches in the used software

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
