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

Entity Relationship Diagram The bellow diagram is what is refered to as an "Entity Relationship Diagram". Its purpose is to show the relationship between different data in the hotel management program ‚ and the actions that are performed on it. And how data from different objects relate to each other. Legend The Data Entities represent data that will need to be stored on the system‚ in general terms. The Relationships represent actions that will occur to the Data Entities‚ or Weak Entities.

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

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

Circular Flow Diagrams Introduction Money flows into and out of the economy. The circular flow diagram explains how money moves through the economic system involving households‚ businesses‚ the government‚ and foreign agents (Editorial Board‚ 2011). Circular flow diagrams are visual models that show firms who employ workers‚ the workers then spend on goods produced by firms‚ and the money is then used to compensate the worker and buy raw materials to make the goods and the circle continues.

Functional Decomposition Diagram An analyst first must understand an organization’s business functions before he or she can begin developing information systems. The functional decomposition diagram (FDD) is a business planning tool that depicts the hierarchy of business functions‚ processes‚ and subprocesses within an organization that are later described in detail using process models (chapter 6). The exercise of breaking down‚ or decomposing‚ the business functions into processes makes complex
