System Architecture 1. Define the term system architecture. Define the term scalability, and explain why it is important to consider scalability in system design. * System architecture translates the logical design of an information system into a physical structure that includes hardware, software, network support, and processing methods. Scalability is the measure of a system’s ability to expand, change, or downsize easily to meet the changing needs of a business enterprise. Scalability is especially important in implementing systems that are volume-related, such as transaction processing systems. 2. When selecting an architecture, what items should a systems analyst consider as part of the overall design checklist? * Before selecting a system architecture, the analyst must consider the following issues: * Enterprise resource planning (ERP) * Initial cost and (TCO) * Scalability * Web integration * Legacy system interface requirements * Processing options * Security issues 3. What is enterprise resource planning (ERP) and why is it important? What is supply chain management? * Enterprise resource planning (ERP) defines a specific architecture, including standards for data, processing, network, and user interface design. It is important because it describes a specific hardware and software environment that ensures hardware connectivity and easyintegration of future applications, including in-house software and commercial packages. ERP also can extend to suppliers and customers in a process called supply chain management. In a totally integrated supply chain, a customer order could cause a production planning system to schedule a work order, which in turn triggers a call for certain parts from one or more suppliers. 4. Explain the term server and provide an example of server-based processing; explain the…...

...IT 460 Unit 1 Kaplan University Harold Boyd The first thing I am going to talk about is JAD (Joint Application Development). Joint Application Development (JAD) is a development technique used to help IT developers build systems. This technique was developed by IBM in the 1970's. In this technique, a team is formed of members of different backgrounds. These members are made up of end-users, management, and IT staff. This team meets and discusses the current project in a number of workshops/sessions. These workshops are used to define the project and to design a solution. Since the team includes actual users of the current system, the system analyst will have a better picture of what the clients would want in a new system. There are four thoughts to consider when working in a JAD. First, the best people that understand the job functions are the people that perform those duties. Needless to say, these people are the best source of information when a question comes up about a particular process. On the other end, IT people understand the "behind the scenes" workings of the current system and can answer question on those topics. These two points introduce the third idea, which is the difference between business professionals and IT professionals. At times, business professionals do not understand subjects in the IT realm (i.e., they are "computer illiterate"). On the other side of the spectrum, IT professionals have issues understanding subject matter in the business realm......

...System Analysis Phase The System Analysis Phase is used to identify requirements for hardware and software components of the proposed system. Our main purpose of the system analysis for Polly's Towing was to identify and document the requirements for an information system to support organizational activities in the payroll and customer billing department. The key output of this phase is a summary document of system/data requirements that explains what the system should be built to, how data should be processed and what technical or support requirements may exist (System Development Life Cycle Policy, 1999, p. 5). During this phase interviews are conducted to identify the needs of the end users. The pros and cons are weighed of the interviews and the requirements are designed based on the information collected.

...THE SYSTEMS DEVELOPMENT LIFE CYCLE LECTURE NOTES DEVELOPING INFORMATION SYSTEMS SOLUTIONS The Systems Development Cycle: The systems approach can be applied to the solution of many types of problems. When this involves the development of information system solutions to business problems, it is called information systems development or application development. Most computer-based information systems are conceived, designed, and implemented using some form of systematic development process. In this process, end users and information specialists design information systems based on an analysis of the information requirements of an organization. Thus, a major part of this process is known as systems analysis and design. When the systems approach is applied to the development of information system solutions, a multistep process or cycle emerges. This is frequently called the information systems development cycle, also known as the systems development life cycle (SDLC). Steps involved and products produced in the traditional information systems development cycle: 1. Systems investigation - Product: Feasibility Study 2. Systems analysis - Product: Functional Requirements 3. Systems design - Product: Systems Specifications 4. Systems implementation - Product: Operational System 5. Systems maintenance - Product: Improved System 1. All the activities involved are highly related and interdependent. 2. Several developmental activities can occur at the same time...
