  • Rita Musoke United Kingdom The design phase factors must be considered when the designing of the input requirements as to assist in the successful creation of the computer system

  • Thomas Ndungo Lekunze Cameroon This process is very important in the designing phase because if the wrong or incorrect inputs are collected, the end product will not fit the purpose of the design and will defeat the essence of the whole production process.

  • Oluwole Fasakin Nigeria This course content is so rich but can I ask one question? Why are most of our examples focused on software development. I think we can consider some other fields so we can have a more broadened view of the course

  • Veronica Brown Australia Most SDLCs today recommend the use of a number of the software engineering techniques for displaying the processes and data of a system. Therefore, the SDLC itself should use these techniques. It could use hierarchy charts, data flow diagrams and structured English to describe the processes. It could use entity-relationship diagrams and data structure charts to describe the data produced. There are many alternative structured techniques for displaying this information. The specific techniques chosen are less important than the fact that a set is used consistently throughout the SDLC.

  • Franklin King Liberia Having established what the system needs to produce to meet its goals, the next area of interest is establishing what data needs to be obtained to produce that output. The design of the input is vital to the successful creation of a computer system. Put simply, the input must be collected from the various sources with a minimal amount of errors, and with the greatest possible speed. A common term used to describe data entry is GIGO - garbage in, garbage out. This expression highlights the importance of input design to the quality of the program produced. The final output will only be as accurate as the data put into the system - and the quality of that data will be partly determined by the quality of the design of the collection methods

  • Larry Covington United States of America prevent duplication of data or re-entering same data more than once

  • Thomas Ndungo Lekunze Cameroon At this stage data is collected from the different sources into a pool in a programmed maner to avoid dublicity an errors and later screened to retain only that wich is relevant to the production of inputs for the sysytem.

  • Thomas Ndungo Lekunze Cameroon Data collection ,analysis and streamlining in alignment to the information require to put in place the respective inputs for the entire system is premodial at this level.

  • Caroline Omoro Kenya is it possible to limit the user choice to pre determined choices?

  • Caroline Omoro Kenya in order to establish what data is needed to obtain required output, the input design is important fot the computer.Therefore Garbage In Garbage Out should be observed.The number of techniques to ensure data collected must be of best quality that will ensure no wrong data is entered.when designing input the programmer should identify the following; -duplicate data -methods of reducing input errors -data validation checks and -input screen method/design

  • Zinabie Tadesse Gebremedhin Ethiopia There are a number of techniques that a good programmer will use to ensure that the data they collect is of the best quality possible. They will limit the opportunities for the user to enter the wrong data, and will ensure the user does not have to enter data twice. 1 Identify methods of reducing input errors 2 Identify data validation checks 3.Input screen/method design
