Epidemiology

Systematic gathering of data for a particular purpose from various sources, including questionnaires, interviews, observation, existing records, and electronic devices. The process is usually preliminary to statistical analysis of the data.

Information application based on a variety of coding methods to minimize the amount of data to be stored, retrieved, or transmitted. Data compression can be applied to various forms of data, such as images and signals. It is used to reduce costs and increase efficiency in the maintenance of large volumes of data.,Using coding methods, such as calculating the changes in a signal intensity, to minimize a series of images from DIAGNOSTIC IMAGING.

Application of statistical procedures to analyze specific observed or assumed facts from a particular study.

Use of sophisticated analysis tools to sort through, organize, examine, and combine large sets of information.,Use of sophisticated tools to parse, organize, and examine textual information.

Software designed to store, manipulate, manage, and control data for specific uses.

The concept should be differentiated from DATABASES, FACTUAL which is used for collections of data and facts apart from bibliographic references to them.

The collection can be automated by various contemporary methods for retrieval. The concept should be differentiated from DATABASES, BIBLIOGRAPHIC which is restricted to collections of bibliographic references.

Databases devoted to knowledge about specific genes and gene products.

Databases containing information about NUCLEIC ACIDS such as BASE SEQUENCE; SNPS; NUCLEIC ACID CONFORMATION; and other properties. Information about the DNA fragments kept in a GENE LIBRARY or GENOMIC LIBRARY is often maintained in DNA databases.
