Task Electric Supply: UML Deployment and Implementation Languages for IT System

Scenario Overview

Task Electric Supply has over 40 years of experience in the residential and commercial field of electrical distribution sector. They specialize in recessed lighting, dimming, lamps, ballasts, and much more from quality manufacturers such as: Juno Lighting, Iris™, Lutron, Philips, Advance, GE, Pass & Seymour Legrand, Lithonia Lighting, as well as many others. The company is passionate about making your experience as a customer satisfying.They are not a retail company and they do not sell direct to the public.

However, they are not only wholesalers but also ready to assist you with product information, product selection, and all your order needs. The company is authorized distributors of all the above products and theykeep many in theirlocal inventory.The company headquarters are in Manchester, United Kingdom. This is where the Chief Executive and the Board are based, along with central support functions like HR, IT, Legal etc. The CEO and Board thus constitute the senior management and are responsible for all strategic decision-making.The company is global, large and complex and, as such, is structured along its product lines, with each product category being headed by a Product Director. Each Product Director is responsible for all aspects of that division and thus makes all tactical-level decision.

They are based around the world. Each Product Director reports directly to the Senior Management back in London. There are eight Product Directors, heading up the following product divisions:•Dimming (several different dimming optionsto achieve the exact light level)•Commercial Lighting (for restaurants,housing and commercial buildings)•Light Bulbs (LED, decorative, energy saving, spotlight and fluorescent tubes)•Wiring Devices (wiring devices portfolio extends to door entry, building automation and domestic circuit protection systems)•Ballasts (the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps.)

Circuit Breakers (Low-voltage, Magnetic, Thermal magneticand Magnetic-hydrauliccircuit breakers.)•Landscape Lighting(private gardens and public landscapes)•FloorHeat(for use under most floor finishes including carpet, wood, laminate, vinyl, tile and stone.)Within each product division there are many different factories and specialized manufacturing/testing facilities –some in urban settings, others in rural areas for field testing. Each site factory is under the control of a Site Managerwho is responsible for all local operational decision-making. Each Site Managerreports directly to the relevant Product Director. The date (DDMMYYYY), country of origin (UK, China, Singapore, etc.) and site number of each product made is recorded for quality control and auditing purposes and encoded into a fixed format Product Code. The serial number of each item and product name is also recorded

The company wishes to implement acomprehensive new IT system to support all these operations and data.You have been selected to lead the project.

This is simply an outline and we can further make our own assumptions and interpret or even extend the scenario.

Using the supplied case study, illustrate how the Unified Modelling Language (UML)may be deployed as part of an Object-Oriented (OO) software development project. You should ensure that you clearly demonstrate the following UML features:Class Diagrams•Activity Diagrams Sequence Diagrams•Use Case Diagrams

Compare and contrast two different commercial UML modelling tools that may be employed to do this work. Provide the web link to each tool

Critically evaluate two implementation languages that could be used to build the planned IT system –one procedural and the other object-oriented. You should include in your answers a brief overview of the following programming constructs and how your two chosen languages implement them: Sequence, selection & iteration Parameter passing and programming interfaces Modularity and programming ‘units.
