Research and Data: General Overview

A.1 Introduction of researchers Research is the process of generating and analyzing information. The system for collecting data for research projects is called research method. You can collect data for theoretical or practical research. These are different profiles of researchers. Insider Inside researcher is a researcher who studies his own organization and workplace. If researchers are involved in the field of their work at their own workplace, that is a researcher.

Data modeling context overview: The data model is based on data, data relationship, data meaning, and data constraints. The data model provides details of the information to be stored and the data model is mainly based on the final product preparing the computer software code for the application or preparing functional specifications to aid in the computer software manufacturing or purchase decision . This figure is an example of the interaction between process and data model. Managing large amounts of structured data and unstructured data is a major function of information systems. The data model represents aspects of the structure, operation, and consistency of the data stored in a data management system such as a relational database. Normally we will not discuss unstructured data such as word processing documents, e-mail messages, pictures, digital audio, video, etc.

Data storage within a digital machine readable medium is sometimes referred to as digital data. Computer data storage is one of the core functions of general purpose computers. Electronic documents can be stored in much less space than paper documents. Bar code and magnetic ink character recognition (MICR) are two methods of recording machine readable data on paper. A recording medium is a physical material that holds information. The newly created information is distributed and stored in 4 storage media (printing, film, magnetic, optical) and viewed in 4 streams (telephone, radio, TV, internet, direct observation). . Digital information is stored in electronic media in various recording formats

Data storage is to record (store) information (data) in a storage medium. DNA and RNA, handwriting, recording, tape and compact disc are all examples of storage media. Recording can be done with almost any form of energy. Electronic data storage requires electricity to store and retrieve data.
