We present a new dynamic index structure for multidimensional data. The considered index structure is based on an extended grid file concept. Strengths and weaknesses of the grid files were analyzed. Based on that analysis we proposed to strengthen t

In the frame of our approach to data integration an extensible canonical model is developed. In the present paper we consider an extension of the canonical model to support materialized integration of data during data warehouse creation. The consider

Within the frame of an approach to information integration an extensible canonical model is created. A principle of kernel extension of canonical model is proposed. In order to create the justifiable data model mapping for heterogeneous databases int

An element algebra supporting the element calculus is proposed. The input and output of our algebra are xdm-elements. Formal definition of element algebra is offered. We consider algebraic expressions as mappings. A reduction of the element calculus

A minimal extension of relational data model for logical modeling of the category of time in databases is offered. The time is considered as a totally ordered set. In the frame of suggested datamodel the homogeneous model of representation of time in
