FIELD: information technology. ^ SUBSTANCE: invention relates to ordered information arrays logically organised into databases stored in physical carriers, e.g. magnetic discs, and to methods of managing databases realised in form of software tools which process information using computers. The method of managing databases involves the following operations. Information is identifying by comparing actual data coordinate values with unified (sorted into types according to recording format) values recorded in the database. The obtained set of standard coordinate values defines the set of cells of address pointers and recording blocks for the identified data. Recording, reading, alteration, deleting and compression of information is carried out through multidimensional space cell referencing and subsequent switching to the data block according to the address pointer. In case of index structure application, multidimensional space cell referencing is carried out by bypassing the binary index tree. ^ EFFECT: reduced database exchange and time for accessing the database. ^ 16 cl, 4 dwg |
