This document outlines the phases of program development: problem analysis, design, coding, testing, and documentation. Problem analysis involves completely defining the problem in writing, understanding the definition, and identifying inputs and desired outputs. Design breaks the project into smaller pieces and describes desired features. Coding translates the design into a programming language. Testing examines outputs for errors and runs the program with different test data. Documentation includes user manuals and materials to help future programmers understand the program.
Program analysis
- 2. Program Development • Tells your computer to dp particular job in desired manner. OR • List of instructions in specific language to tell the computer to do job in sequence.
- 3. Phases of program development Whenever any problem has to be converted into a program then following steps are to be followed: • Analyzing the problem • Designing the solution • Coding the solution • Testing the solution • Documenting the solution
- 5. Problem Analysis • Complete definition in written form • Understanding the written definition • Defining the input facts and identifying the source • Produce desired results • Major areas involved: Input, Process, Output, Storage
- 6. Program Design • Breaking the project into small pieces and designing logic for each part. • Describes desired features and operations in detail, including screen layouts, business rules, process diagrams, pseudocode and other documentation.
- 7. Program Coding • Translating the program design into appropriate computer programming language. • Approach: – Top to bottom – Bottom to top
- 8. Testing Programs Examine the output screen and determine what is wrong? • Check for alignment problems with output information. • Check for missing information • Verify computation information and check formula • Take different set of test data and run the program.
- 9. Documentation • User documentation – User Manual • Programmer documentation – Copy of original written specifications – Copy of input, output, process and storage analysis – Copy of source code, flowcharts, pseudo code or other designs if used. – Printed copy of input facts used to test program – Printed copy of all possible output reports or screens.
