1.What is system analysis?
Systems analysis is the study of sets of interacting entities, including computer systems analysis. This field is closely related to requirements analysis or operations research. It is also "an explicit formal inquiry carried out to help someone (referred to as the decision maker) identify a better course of action and make a better decision than he might otherwise have made." 2.Information System Components.

The main components of information systems are computer hardware and software, telecommunications, databases and data warehouses, human resources, and procedures. The hardware, software, and telecommunications constitute information technology (IT), which is now ingrained in the operations and management of organizations. 3.How Business use Informatiomn System

STUDENT LEARNING OBJECTIVES Essentials of Business Information Systems Chapter 2 E-Business: How Businesses Use Information Systems What are the major features of a business that are important for understanding the role of information systems? How do information systems support the major business functions: sales and marketing, manufacturing and production, finance and accounting, and human resources? How do systems serve the various levels of management in a business and how are these systems related? How do enterprise applications, collaboration and communication systems, and intranets improve organizational performance? What is the role of the information system’s function in a business?

4. Research for the system development life cycle (SDLC).
The Systems development life cycle (SDLC), or Software development process in systems engineering, information systems and software engineering, is a process of creating or altering information systems, and the models and methodologies that people use to develop these systems. In software engineering, the SDLC concept underpins many kinds of software development methodologies. These methodologies form the framework for planning and controlling the creation of an information system:[1] the software development process.
