1. what is the traditional approach to systems development?
2.what is the object oriented approach to systems development?
3.what text books,journals and/or websites might be useful to search for articles about comparing and contrasting the traditional and object oriented approaches to systems development?
Following are the various fact finding techniques for the above,which might vary with each approach
· Document review
· Observation
· Questionnaires and surveys
· Sampling
· Research
With the traditional approach to systems development , document review is the first and foremost technique in finding the facts.document review is nothing but it is a plan to implement a project and it explains how the system works and then the observation is also used to verify the statements or queries to implement in systems development.In traditional approach the questionnaires and surveys doesnot satisfy because in this we will discuss a lot about how the projects are going but in this we cant implement this technique.In traditional approach we will take some records,files to perform the project
So in this sampling is satisfied.And finally research is satisfied because in traditional approach we also get the information through mails,news and books.These are the fact finding techniques that support traditional approach to systems development.
As with object oriented analysis where as the processors and data are treated as separate components,the only fact finding technique used for this approach is research only.Where research identifies an issues own properties and inherited properties for example the person class includes the student objects in which we will identify the characteristics.The research technique is effectively used in sending information between objects.None of the other fact finding techniques are useful for the object oriented approach to systems development , with document review because in this we use only how to plan but in object oriented this we cant plan anything we simply implement a program through the object oriented programming languages.And similarly with observations,questionairesand surveys,sampling the object oriented analysis approach to systems development doesnot satisfy the fact finding techniques.In object oriented approach to systems development we satisfy onlyresearch technique the remaining all is not satified.
The fact finding technique that is used to find the textbooks,journals,website we mostly use the questionnaires and surveys,research techniques.In this we use how to find the sites about the information regarding the systems development in traditional approach and object oriented approach.In this these are the fact finding techniques that are mainly used in traditional approach and object oriented approach to systems development.
