tailieunhanh - Lecture Systems analysis and design methods (7/e): Chapter 2 – Whitten, Bentley

Systems analysis and design methods are used to develop information systems for organizations. Before learning the process of building systems, you need a clear understanding of the product you are trying to build. This chapter takes an architectural look at information systems and applications. | Chapter 2 Information System Building Blocks Objectives Differentiate between front- and back-office information systems. Describe the role of information systems architecture in systems development. Identify three high-level goals that provide system owners and system users with a perspective of an information system. Identify three technologies that provide system designers and builders with a perspective of an information system. Identify three areas of focus for an information system 2- Objectives (cont.) Describe four building blocks of the KNOWLEDGE goal for an information system. Describe four building blocks of the PROCESS goal for an information system. Describe four building blocks of the COMMUNICATIONS goal for an information system. Describe the role of network technologies as it relates to Knowledge, Processes, and Communications building blocks. 2- 2- Front- and Back-Office Information Systems Front-office information systems support business functions that | Chapter 2 Information System Building Blocks Objectives Differentiate between front- and back-office information systems.

Marketing Sales Customer management Back-office information systems support internal business operations of an organization, as well as reach out to suppliers (of materials, equipment, supplies, and services). Human resources Financial management Manufacturing Inventory control 2- A Federation of Information Systems 2- Information System Applications 2- Information Systems Architecture Information systems architecture - a unifying framework into which various stakeholders with different perspectives can organize and view the fundamental building blocks of information systems. 2- High-Level Goals of System Owners and System Users Improve business knowledge Improve business processes and services Improve business communication and people collaboration 2- Technology Perspectives of System Designers & System Builders Database technologies that support business accumulation and use of business knowledge .
