It is often, though not exclusively, studied as a branch of computer science and information technology and is related to database, ontology and software engineering.

Information science is primarily concerned with the structure, creation, management, storage, retrieval, dissemination and transfer of information. Information science also includes studying the application of information in organizations, on its usage and the interaction between people, organizations and information systems. Within information science attention has been liven in recent years to human computer interaction (HCI) and to the ways people generate, use and find information. Two definitions of Informatics taught in an introductory class at Indiana University Bloomington are "The Art, Science and Human Dimensions of IT" and "The study, application, and social consequences of technology". Informatics focuses on understanding problems and then applying information (and other) technology as needed. In other words, it tackles the problem first rather than technology first, as has been too often done in many areas, such as business and scientific research.

A note on international terminology. The words informatique in French and Informatik in German do not mean the same as the English informatics. Rather, they are much closer to computer science. Information theory is a branch of the mathematical theory of probability and mathematical statistics, that quantifies the concept of information. It is concerned with information entropy, communication systems, data transmission and rate distortion theory, cryptography, data compression, error correction, and related topics. It is not to be confused with library and information science or information technology.

Econometrics literally means 'economic measurement'. It is the branch of economics that applies statistical methods to the empirical study of economic theories and relationships. It is a combination of mathematical economics, statistics, economic statistics and economic theory. The two main purposes of econometrics are to give empirical content to economic theory and also to empirically verify economic theory. For example, econometrics could empirical; verify if indeed a given demand curve slopes downward as economic theory would suggest. Empirical content is also given in that a numerical value would be given to this slope, while economic theory alone is usually mute on actual specific values.

An econometrician often changes qualitative statements into a quantitative mathematical form that lends itself to measurement. These statements can then be empirically proven, disprove n, measured, and compared. Econometrics differs from statistics done in other fields since controlled experiments are often impractical, so econometrics has to frequently deal with data as is. Arguably the most important tool of econometrics is regression analysis (for an overview of a linear implementation of this framework, see linear regression). Econometric analysis can often be divided into time-series analysis and cross-sectional analysis. Time-series analysis examines variables over time, such as the effect of interest rates on national expenditure.

Cross-sectional analysis studies relationship between different variables at a point in time. For instance, the relationship between income, locality, and personal expenditure. When time-series analysis and cross-sectional analysis are conducted simultaneously on the same sample, it is called panel analysis. If the sample is different each time, it is called pooled cross section data. A simple example of a relationship in econometrics is: Personal Expenditure = Propensity to Spend Income + random error This statement asserts that the amount a person spends is dependent on their income and their willingness to spend money. If we can observe personal expenditure and income techniques such as regression analysis can then be applied to find the value of the coefficient here just the propensity to spend.

The estimated coefficient can then be compared across samples (such as different countries or income brackets) and conclusions made. -., , , , , , , ... , ... informatique, Informatik., informatics., . -, , , , ) -, , , ., , , , . )., (, ).
