Many scholars have defined research in a different ways. But the common definition used for the research is as follows:
Research is a systemic approach in collecting, organizing, analyzing and evaluating the data
The main issue in the research process is to identify the research problem. All the factors which are linked should be carefully collected, organized, analyzed and evaluated to find the solution to that particular research problem. The main activity is to properly link the related factors. There are lot of chances to link the factors which are not related to the research and thus if these factors are linked to find the solution, ultimately these unlinked factors will lead to the wrong analysis and the proper solution will not be evaluated for the research problem. So, finding the factors for the problem and linking them together is the important activity for finding the solution for the research problem.
