...Pre-Requisite: Completion of 1st Year Courses Introduction: Systems Design is a central part of systems development. It comprises the process of turning a set of user requirements into an implementable system and encompasses various activities to achieve this end. Alternative models are challenging the traditional systems development life cycle. Alongside this, two approaches to systems development are emerging: the traditional structured approach; and the object oriented approach. The systems design activity will be studied in the context of these trends. Students should make themselves familiar with at least one traditional approach (e.g. SSADM) and one object oriented approach (e.g. UML). Aims: To understand the role of systems design within various systems development life cycles To develop awareness of the different approaches that may be taken to systems design To understand and apply the tools and techniques that are currently used by systems designers Formatted: Superscript Objectives: Describe different life cycle models and explain the contribution of systems design within them Discuss various systems development approaches and explain their strengths and weaknesses 1 30/09/1123/09/10 Evaluate the tools and techniques that may be used by a system designer in a given context Use appropriate methods to produce a system design for a given scenario Provide suitable systems documentation for a design Discuss the CASE tools currently available Content: Week...

...prepared by the Information Technology (IT) team describing a new information system required by our Advanced Services Network Consulting Engineers (NCEs). The information provided has been summarized and is intended to provide an overview of the proposed project. Executive Summary Within our organization we have a group of Network Consulting Engineers (NCEs) that provide Planning, Design, Implementation, and Operational (PDIO) services to contracted enterprise and service provider clients. On a number of recent occasions, it has come to light that one NCE is struggling with a design or planning issue that has already been addressed by another NCE. And in some cases, the solutions provided to our clients were not consistent between the NCEs. It has been determined a new system is needed that will provide an orderly and organized data repository that would be available to all NCEs. This system needs to provide an easy method for the NCEs to access and leverage previously defined design solutions. This system will provide several key benefits to the NCE team: ▪ NCE will be able to search for data related to the solution being considered ▪ NCE will save time in that we will not "reinvent the wheel" ▪ NCE provided solutions will be more standardized ▪ Using the same solution repeatedly simplifies supporting our solutions ▪ Allows our NCEs to be able to provide backup to one another ▪ With standard solutions we increase the probability that we will continually...

...------------------------------------------------- 1. Explain the main difference between a file-oriented system and a database system. A file-oriented system utilizes data in a regular OS file based format where a database system uses a database engine that organizes data in a database in a table format utilizing rows for each record. 2. What is a DBMS? Briefly describe the components of a DBMS. DBMS stands for Database Management System. A DBMS is a collection of tools, features, and interfaces that enables users to add, update, manage, access, and analyze the contents of a database. A DBMS is made up of a DML (data manipulation language), Schema and subschemas, Physical data repository, and an Interface to allow access to the database from DBA’s, Users, and Related Information Systems. 3. Describe a primary key, candidate key, secondary key, foreign key, and common field. Primary Key – a field or combination of fields that uniquely and minimally identifies an entity. Candidate Key – Any field or combination of fields that can act as the primary key but are not. Secondary Key – Any field of combination of fields that can be use to identify a entity. Foreign Key – A field that exists in an entity that is the PK of another entity. Common Field – An attribute (field) that appears in more than one entity (record). 4. What are entity-relationship diagrams and how are they used? What symbol is used to represent and entity in an ERD? What symbol...

...concepts that are the basis for current computers. The computer lies at the heart of computing. Without it, most of the computing disciplines today would be a branch of theoretical mathematics. To be a professional in any field of computing today, one should not regard the computer as just black box that executes program by magic. We, students of computing should acquire some understanding and appreciation of a computer system’s functional components, their characteristics, their performance, and their instruction. There are practical implications as well. In describing computer systems, a distinguishing feature is frequently made between Computer Organization and Computer Architecture. Computer Organization explains the function and design of the various units of digital computers (displaying information as numbers rather than with hands and a dial) that store and process information. It also deals with the input units of the computer which receive information from external sources...

...benefit analysis in data warehouse design” This research seeks to address the issue of identifying the set of data which has the potential for producing net value for the organization through a model that helps to perform the cost benefit analysis. Typical data warehouse store a set of data tables which are of 2 types: base table and materialized view that are generated from the existing data tables. Data warehouse is used to support a set of decision support views. There is a need to identify the set of DSV’s that provide the most net value to the organization and this will determine the set of data tables that should be stored in the data warehouse. DSV’s are used to perform particular tasks that are beneficial for the organization and also helps to achieve the organization goals. In the data warehouse formulation phase who needs what data has to be considered which is identifying the needs of the IT and business users of the DW. According to Kalfus et al, all data are essential and must be stored and interesting patterns can be extracted from it. But the disadvantage of this is if all the data is stored the space consumed by it will be very high. Data warehouse quality is also an important factor for those who design the use of systems that support decision makers. The cost for improving the quality is high. The cost benefit analysis can be used to identify the DSV’s that give the most net value to the organization, suitable quality levels and the data tables that are to be...

...Introduction This memorandum addresses our recommendation for Product Data Management and Visionary Design System employees. First, it states the principal and agent relationships. Second, it addresses the sources of problems with PDM. Third, it discusses solutions and recommendations for PDM and VDS employees. Finally, it discusses other organizational changes and concludes with a summary of our recommendations. Principal-Agent Relationships The PDM software provides organizational efficiency for VDS. As a result, the VDS executives serve as the principal and PDM is the agent. The executives of VDS pride themselves on working closely with the customers and departments as well, therefore, VDS serves as agents to customers. VDS has the greatest potential to achieve a great competitive advantage because it captured a large portion of the market from its previous services. As a result, VDS has the advantage of the opportunity to explain its extensive benefits for consumers’ design process during its consultations. PDM needs VDS’s respected brand in the market and it has the technological advances to bring in greater revenue for VDS as a whole. Sources of Problems with PDM VDS’s advantage develops from its consultation advice and the benefits and simplicity of the PDM software; however, without the cooperation and understanding from the Sales Representatives, this advantage fails. The consulting services were first cut to save money, but without them, the PDM service...
