          RDBMS. Includes development, data compression, English-like commands
          and automatic or customized screen and report formatting. Provides
          abbreviation capability, ad hoc reports and operations.Îïèñàíèå-Ò 
          RDBMS. Offers a random binary file containing tables, dictionary,
          abbreviations and compressed data. Provides a self-contained data
          dictionary that names and classifies data elements. Places no limits
          on number of elements, items or file size. Provides dynamic memory
          allocation techniques to handle processes in memory, or use
          supplemental disk work space for long sorted reports. Allows fields
          and names up to 255 characters. Makes all elements key elements for
          query purposes, and every element in a sorted report a sort key.
          Makes databases smaller than input files with compression utilities.
          Includes a special unknown value to represent missing or erroneous
          data. Recognizes the unknown value in queries and computations. Does
          not distort averages or other computations. Provides the ability to
          hide individual items and elements for security purposes. Restores
          hidden items and elements, or purges them during the copy data base
          process. Updates using a reverse linking process to maintain database
          integrity. Offers three main data types. Offers computations in
          double precision providing 15 digits or more. Offers report two
          outputs, one to the terminal, the other to a printer. Automatically
          formats reports using information from the data dictionary. Includes
          abbreviation capabilities. Checks incoming data against the
          dictionary for validity. Includes four levels of error reporting for
          input data. Allows databases to be partially or completely replicated
          on mainframes and micros by up- or down-line loading using ASCII
          files.ÒÅÐÌÈÍÛ
