    Thomas Ndungo Lekunze Cameroon Focus at this stage for the designer has to be on; - source of data which is intrinsically linked to the targeted audience - the quality and validity of data collected - the mechanism to screen data collected to suit with the required inputs for the envisaged design.

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. When designing input, the programmer should put all these in considerations. i. Identify duplicate data ii. Identify methods of reducing input errors iii. Identify data validation checks iv.

    Jahidul Islam Bangladesh 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. 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. When designing input, the programmer should: Identify duplicate data - Efficient program design requires that the program only collect and store each data element once. Programmers should analyse the data requirements and identify where data is used more than once and ensure it is collected just once. It is important to do this - while it may be easier to collect data more than once, rather than create highly complex data structures, this approach compromises the integrity of the information produced, as it allows for more input errors and the creation of conflicting outputs.
