Sub system is basically a module of the system performing a particular task. A big system may be seen as a set of interacting smaller systems known as subsystems or functional… units each of which has its defined tasks. All these work in coordination to achieve the overall objective of the system.
he advantages of questionnaires# Practical# Large amounts of information can be collected from a large number of people in a short period of time and in a relatively cost effe…ctive way# Can be carried out by the researcher or by any number of people with limited affect to its validity and reliability# The results of the questionnaires can usually be quickly and easily quantified by either a researcher or through the use of a software package# Can be analysed more 'scientifically' and objectively than other forms of research# When data has been quantified, it can be used to compare and contrast other research and may be used to measure change# Positivists believe that quantitative data can be used to create new theories and / or test existing hypothesesThe disadvantages of questionnaires# Is argued to be inadequate to understand some forms of information - i.e. changes of emotions, behaviour, feelings etc.# Phenomenologists state that quantitative research is simply an artificial creation by the researcher, as it is asking only a limited amount of information without explanation# Lacks validity# There is no way to tell how truthful a respondent is being# There is no way of telling how much thought a respondent has put in# The respondent may be forgetful or not thinking within the full context of the situation# People may read differently into each question and therefore reply based on their own interpretation of the question - i.e. what is 'good' to someone may be 'poor' to someone else, therefore there is a level of subjectivity that is not acknowledged# There is a level of researcher imposition, meaning that when developing the questionnaire, the researcher is making their own decisions and assumptions as to what is and is not important...therefore they may be missing something that is of importance
system analysis and design is a process in doing a program........ and there a step on how to do a program first you study the data , second is analyze the data or program, th…ird is draw your data, fourth is coding the data, next is testing the data that you do,next is implication and the last is maintenance. :-) hehehe
The objectives are to determine specific needs of a system and ultimately facilitate a comprehensive design around these needs. ☺ describe different life cycle models an…d explain the contribution of the system analysis and design within them; ☺ discuss various approaches to systems analysis and design and explain their strengths and weaknesses; ☺ evaluate the tools and techniques of systems analysis and design that may be used in a given context; ☺ use appropriate methods and techniques to produce an analysis of a given scenario; ☺ use appropriate methods and techniques to produce a system design for an given scenario; ☺ provide suitable documentation for systems analysis and design activities
That`s what me too searching for... What is input designs in system design?
Systems are created to solve problems. One can think of the systems approach as an organized way of dealing with a problem. In this dynamic world, The subject System Analysis …and Design, mainly deals with the software development activities.
Leveling is the process of drawing a series of increasingly detailed diagrams, until all functional primitives are identified.
The purpose of systems analysis and design is for a business to increase their efficiency, because when you look at a current system you will see flaws that need fixed ans wit…hin the new system that you design you will take these into consideration. A new system will make the the business more profitable.
Information gathering is an art & science.
what is systems documentation in system analysis and design? what is systems documentation in system analysis and design? Systems Analysis and Design: Mary …Pozo Answered: Practitioners of systems analysis are often called up to dissect systems that have grown haphazardly to determine the current components of the system. In business, for example, if a retail business is using an old POS system, a consultant analyst could recommend updating to a better system like Microsoft Dynamics NAV (business management solution) or MS Retail Management Solution.
Because people can think and write natural language much quicker than they can code, so you can iterate through different ways of doing it in your head to find a good solution… much quicker than you can rewrite a program. Joel on Software has an article on why to do design, see related link. A quote from the article: You can not change things in code "just as easily" as you could change them in the design documents. People say this all the time and it's wrong. "We use high-level tools these days, like Java and XML. We can change things in minutes in the code. Why not design it in code?" My friend, you can put wheels on your mama but that doesn't make her a bus, and if you think you can refactor your wrongly-implemented file-copy function to make it preemptive rather than threaded as quickly as I could write that sentence, you're in deep denial.
Types of System Following are some of the types of System Deterministic System: A system which acts in a predictable manner where stepwise execution and the output is alread…y known is called as Deterministic System. example: A program to find the factorial of the entered number. Probabilistic System: The system which acts in a unpredictable manner and where the outcome is not predictable is known as a Probabilistic system. There is always a some degree of error present in such system. example: Weather forecasting. Open System: The system which interacts with the environment is known as an Open system. These system change their organization in response to the changing environment. example:Organizational system. Closed System: A system which doesn't interact with the outside environment is known as the closed system. All the operation are controlled automatically by the system itself. example:Chemical reaction in the sealed tube.
I would say technical architects...
