5.2.1 Physical Design Process We all have the concept of dimensional modeling technique. Logical model can be built from dimensional modeling technique. Physical model can be derived from logical model. Computing platform‚ the database software‚ hardware‚ and any third-party tools need to be considered while designing physical model. Logical Data Model: It comprises of all entities and their relationships. Each entity includes their attributes and primary keys. Foreign keys are specified in this

3HRC (HR) Understanding organisations and the role of Human Resources Activity 2 The following report contains information on how Human Resources can support the organisation with both internal processes and meeting key business objectives. Human resources and the services they provide can be seen as the crucial link between staff and the achieving the business goals and objectives. They are there to create‚ produce and maintain all policies and procedures. And more importantly ensure that

CIST 1601 Information Security Fundamentals Physical Design Phase – Intrusion Detection Assignments Answer the following questions. Use complete sentences. 1. How does a false positive alarm differ from a false negative one? From a security perspective‚ which is least desirable? A false positive attack is where the system IDPS was alarmed but no attack ever occurred. The false negative is where an actual attack occurs and the IDPS isn’t alarmed at all. The least desirable would definitely be

He showed us the famous channel in the world the Istanbul‚ Turkey. He shared his experiences in navigating in this channel. He taught us the Traffic Separation Scheme (TSS). It has the north bound and south bound just like the road in land. Counter flowing is not allowed also in narrow channeling. When joining the Traffic

Abstract The “Chemical Kinetics” experiment was done to investigate the changes in the rate of reaction under the effect of concentration‚ temperature‚ and presence of a catalyst. It was determined that as the concentration of reactants and the temperature increases‚ the rate of the reaction increases as well. Also‚ the reaction was run by the presence of catalyst‚ and the rate of the reaction increased drastically in the presence of it. The order of the reaction with respect to each reactant

More than 80 percent of the youth do not do enough aerobic physical activity to meet the guidelines for Healthy People 2020. (Physical Activity‚ 2011‚ pg.1). At least half of youth do not engage in physical activity that promotes long-term health. (Exercise‚ 2011

Activity 1: Simple diffusion Introduction: Simple diffusion is the net movement of substances from a region of high concentration to a region of low concentration so its overall net movement is along the concentration gradient‚ simple diffusion does not require energy therefore it is ’passive’‚ substances are diffused across the membrane between the phospholipids.

Usually‚ the changes that occur within the bar is not instantaneous and will be different at both end. 2. Radial conduction heat transfer Fluid motion that resulted by force over the surface by an external source‚ such as fans or pumps. Small movement of air is generated which limits the heat transfer rate from the hotter surface to the surrounding air
