Reflective model In this report I am going to evaluate the difference between Gibbs (1988) and Kolb (1984)‚ drawing primarily on Gibbs’s reflective model. The Kolb cycle 1984 was published before Gibbs 1988‚ David A. Kolb published his conception after an experimental test on a book “Experience as the Source of learning and development” while Gibbs published his theory by developing on the existing Kolb cycle (ehow[07/10/2014]). Kolb’s theory is based on 4 cycles. It starts with doing something

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.

1. What is an Entity Relationship Diagram? An entity relationship diagram is a graphical representation of an organisation’s data storage requirements. Entity relationship diagrams are abstractions of the real world which simplify the problem to be solved while retaining its essential features. Entity relationship diagrams are used to: identify the data that must be captured‚ stored and retrieved in order to support the business activities performed by an organisation; and identify the data required

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

The Entity Relationship Diagram (ERD) depicts a conceptual data model that incorporates some of the important scientific information about the real world. It adopts a natural view that the real world consists of entities and relations (Chen‚ 1976). One objective of the ERD is to create a simple‚ easy to understand and conveniently presented data model consisting of entities‚ attributes‚ relationships and cardinalities. The model serves as tool for database design‚ where the model can facilitate communication

Producers are the plants and the tress in the ecosystem that provide the energy to the ecosystem. As for the desert the producers are cactus and grass. The consumers of the ecosystem are in three different kinds‚ they are herbivores‚ carnivores‚ and omnivores. Herbivores are the consumers

Component Diagram Notations The component diagram’s main purpose is to show the structural relationships between the components of a system. In addition‚ component diagrams are useful communication tools for various groups. In creating a component diagram‚ there are different notations that can be used to show the different relationship of each component within the system. The component diagram notation set now makes it one of the easiest UML diagrams to draw: * COMPONENT A component can
