Data, information, and knowledge

In the endeavor to deepen understanding of chemistry, many an experiment has been performed, and many data have been accumulated. Chapter 6, on databases, gives a vivid picture of the enormous amount of data that have been determined and made accessible. The task is then to derive knowledge from these data by inductive learning. In this context we have to define the terms, data, information, and knowledge, and we do so in a generally accepted manner. 

Data, information, and knowledge can have short shelf-lives... 

The terms data, information, and knowledge are often used interchangeably for diverse purposes by researchers in all scientific disciplines. In the scientific enterprise, however, they are not interchangeable, despite arguments to the contrary. As a matter of fact, Chemometrics, the subject of this Symposium, may spring at least in part from the real...

In modem approaches to drug discovery there are numerous approximations, assumptions and accuracy or error limitations. Inevitably, this affects the reliability of the data, information and knowledge with the obvious implication that some of the knowledge will be incorrect. Appreciating the differences between the types of parameters can help to ensure that when possible the appropriate statistical techniques are used and that the reliability of knowledge is considered when making important decisions. 

It is crucial to distinguish between the terms data, information, and knowledge so that vve can think clearly about the goal of data accumulation in our own industry sector. There are two views a tiered hierarchical view and a more formally correct scientific view. 

Integrated Because the warehouse relies on data, information, and knowledge produced by other software applications or humans, a data warehouse is a solution that is well integrated into the software environment of an organization. A unique representation of data is required for effective analytical processing of large amounts of information stored in a data warehouse. 

Expert systems are literally applications rather than theoretical research topics. Their application addresses parts of a larger context that incorporates a series of different data, information, and knowledge management systems. Interoperability is therefore one of main features of an expert system.

Data, information and knowledge or insights are different, but interrelated. Figure 37-1 illustrates the logical flow of data to information, knowledge and insights. 

The exchange of data, information and knowledge is supported by a wide range of methods and standards, as detailed in Chap. 6. The most well-known and widely used standard in this regard is ISO 10303 Standard for the Exchange of Product model data (STEP), with its various application protocols (APs), which is maintained and updated continuously. 

The three cases here illustrate public health informatics concerns with data, information, and knowledge management in areas where local governments have responsibilities for service delivery—maternal and child health, disaster rapid response, and promotion of healthy lifestyles. 

The material scope of the data, information and knowledge transfer in a supply chain must be broad, as the marketing and supply of a product or service require measures involving research and development, finance, purchase, production, logistics, marketing and sales. 

Thus, data, information and knowledge on the purchase market suppliers, product structure and design the subjects of flow (raw materials, production materials, work-in-progress, finished products, packaging, returns, waste and residual products) the sales market and end-consumers are aU transferred in supply chains. This means that there are multiple soiuces of data. Information and knowledge. These sources are presented in Table 6.1, taking into accoimt the internal and external sources, divided into primary and secondary somces.
