7.2. The system of classification and coding of information.
The importance of systematizing information for its automated processing. The concept of classification and classifier. Objects of classification. The concept of classification. Hierarchical classification system. Facet
classification system. The concept of code, coding, coding system, code alphabet, code base, code length, code digit. Registration, classification, sequential, and parallel coding systems. Sequential, serial, positional, matrix, repetition, and combined coding systems.
Forms of classifiers. Types of classifiers. The State System of Classification and Coding of Information (SSCC), its functions. The purpose and function of
barcoding.
7.3. Unified documentation system.
Properties of a document as a component of information support.
The concept of a unified documentation system (UDS). Designing forms
for primary documents. Designing forms for source documents. The concept
of an electronic document form.
7.4. Machine-based information support.
Composition of machine-based IS. Composition of the machine information base. File classification. Input files, base files, operational files, reference and regulatory information files, working files, intermediate files, service files,
archive files. Independent files. Organization of logically interrelated
files in a database. Composition of the means of organizing and maintaining the machine IB. Software
tools for organizing and maintaining the IB.
