We know that data is the foundation of all information. A few aspect of data, source of data and methods of collecting the data for the purposes of converting them into information are described in the paragraphs which is follow:-
Primary Data and Secondary Data:
Data are the raw material used for obtaining information. Data is derived form a number of sources, both internal as well as external. If the data is collected for the first time by the researcher, it is Classified as a Primary data. if however, data is borrowed by the researcher form the other sources, it is referred to as secondary Data.
- Primary Data: Primary data could be gathered directly form the respondent. Different techniques like Observations, questionnaires, interviews etc. can be use for obtaining primary data, which can then be converted into information.
- Secondary Data: Secondary data sources include internal records as well as external records. Sources like Newspaper, Magazines, trades journals, Governments publications, Government policy documents, research reports, web sites etc are includes in secondary data Sources.
Management Information System and Information Concept
Management information system should provide the information which has a surprise value and which reduces the uncertainty in decision making. it should simultaneously build the knowledge base. While designing MIS due regard should be given to the communication theory of transmitting the information form the sources of the destination. MIS should use the redundancy of data and information as a measure to control the error in communication.
Information is a quality product for organization. The quality can be ensured if the inputs of the management information system MIS are controlled on the factors of impartiality, validity, reliability, consistency and age. MIS should give regard to the information used for planning, performance, control and knowledge database.
Recognizing that the information may be misused if it falls into wrong hands, The MIS design should have the features of filtering, blocking, suppression's and delay delivery.
