Formalized description of basic structure of representation of matrix universal object-relational databases
I. A. Miklyaev "Sevmashvtuz" – Severodvinsk Branch of Saint Petersburg State Marine University
Abstract:
A formal description of the relational structure of data representation (SRD) is expanded by its foreign level, corresponding to a set of databases that allows simultaneous work with several matrix universal object-relational data-bases (MUORDB). In MUORDB the possibility of formation of complex units of information is realized, for this the fifth dimension has been set. This does not contradict the properties of atomicity of relational databases. The concept of MUORDB formation is based first on the layout of the relational SRD in a joint matrix structure, i.e. metadata are represented in the same form as substantive information relational SRD. In MUORDB the structure of the tuple is deepened by one dimension and its element is extended from two to five components: a reference to a field (attribute) of the table, meaning, the boundaries of time of limited information relevance of the tuple element, the number of the parent element in the tuple, designed for tree-like structure of complex information unit. The fundamental step in creating a MUORDB database is to develop a universal data type. The value of the generic type is placed in a dynamic array of byte type, which hosted at the seventh dimension of the MUORDB matrix. Thus, the final seven-dimensional matrix, consisting of six dynamic arrays and the sixth static array responsible for the tuple element is obtained.
