You will get good results from our work Brazil Email Database Primary data are obtained as a result of so-called field marketing research conducted specifically to solve a specific marketing problem; they are collected through observations, surveys, and experimental studies, usually carried out on a part of the total population of objects being studied—a sample.
Secondary data , used in so-called desk marketing research, refers to data previously collected from internal and external sources for purposes other than marketing research. In other words, secondary data is not the result of special marketing research.
Since desk research is the most accessible and inexpensive method of conducting marketing research, the collection of secondary data usually precedes the collection of primary data. For small and sometimes medium-sized organizations, desk research is practically the dominant method of obtaining marketing information.
Internal sources include organizational reports, interviews with sales personnel and other managers and employees, the marketing information system, accounting and financial reports, reports from managers at shareholder meetings, sales personnel reports, business trip reports, customer complaint and claim reviews, letters of thanks, production and R&D plans, minutes of management meetings, business correspondence, etc.
The secondary information that a continuous monitoring system of the external marketing environment must work with is extensive and, as a rule, scattered across a multitude of sources, which are almost impossible to list in full.
