Abstract: A digital computer system and method for storing and retrieving data contained in a "relational data table" in such a way that individual items of data are readily accessible and the data itself is compressible. The items of data are arranged in the table in a plurality of rows and columns. The items of data in each given column are of the same type (fixed length character, variable length up to a prescribed maximum length, etc.). The items of data are arranged in a particular data format which comprises a plurality of "column descriptor" or "C" records, each of which is associated with one column of the table, followed by a plurality of "data" or "D" records which include the items of data in the table. The D records and C records contain the following information: Each D record includes one or more of the items of data from a particular table row. It is therefore associated with this table row and with at least one table column.
