Business System development Lecture in Hindi and Urdu |Handout Notes

About the course

• Systems Analysis and Design (SAD) is an exciting, active field in which analysts continually learn new techniques and approaches to develop business systems more effectively and efficiently.
• The course gives an understanding of organizational behavior concepts like change management and team building which are very important for any type of business process.
• It gives the information on how all projects require analysts to gather requirements, model the business needs, and create blueprints for their business system.

The course is comprised of 32 lectures and is divided in following parts:

Part – 1: Foundations for Systems Development

Part – 2: Systems Planning and Selection

Part – 3: Systems Analysis

Part – 4: Systems Design

Part – 5: Systems Implementation and Operation

Lecture 1: The Systems Development Environment

Outlines

• Information systems analysis and design.
• Different types of information systems.
• The information Systems Development Life Cycle (SDLC).

Objectives

• To understand and distinguish between different types of Information Systems.
• To understand and distinguish between different SDLC

Introduction

Information Systems Analysis and Design

• Complex organizational process whereby computer-based information systems are developed and maintained

Application Software

• Computer software designed to support organizational functions or processes

Systems Analyst

• Organizational role most responsible for analysis and design of information systems
• A Modern Approach to Systems Analysis and Design
  • 1950s: focus on efficient automation of existing processes
  • 1960s: advent of 3GL, faster and more reliable computers
  • 1970s: system development becomes more like an engineering discipline
  • 1980s: major breakthrough with 4GL, CASE tools, object oriented methods
  • 1990s: focus on system integration, GUI applications, client/server platforms, Internet
  • The new century: Web application development, wireless PDAs, component-based applications

Types of Information Systems and Systems Development

Transaction Processing Systems (TPS)

• • Automate handling of data about business activities (transactions)
  • Process orientation

Management Information Systems (MIS)

• • Converts raw data from transaction processing system into meaningful form
  • Data orientation

Decision Support Systems (DSS)

• • Designed to help decision makers
  • Provides interactive environment for decision making

Involves data warehouses, executive information systems (EIS)

• • Database, model base, user dialogue
  • SummaryIn this lecture we learned about:
    • Information systems analysis and design.
    • The different types of information systems.
    • The phases in the information Systems Development Life Cycle (SDLC).

Overview of Next lecture

We will continue our discussion on SDLC

Precisely, we will talk about the problems with the existing waterfall approach

We will also see some other SDLC: Methodologies
