Methods of upgrading the standard modules typical configuration based technology platform "1C: Enterprise 8" with minimal modifications
Engineering Education # 08, August 2012
DOI: 10.7463/0812.0450231
In this article the authors propose a method of upgrading the standard configuration "1C: Payroll and HR budget entity 8" with minimal modifications of standard objects. The method consists of three schemes to change the types of configuration, through which one can describe the basic concepts of the subject area. The application of this technique allows to automatically install updates, to differentiate objects of typical configuration from objects that were improved. The authors show urgency of development of the proposed method in the implementation of the standard configuration "1C: Payroll and HR budget entity 8" in universities. Application of the method allows to refine the typical configuration of the structure, staffing and personnel records.
Overview of methods of creating systems based on temporal relational database
Engineering Education # 08, August 2012
DOI: 10.7463/0812.0441884
The article presents an analysis of approaches to implementation of temporal systems based on relational database. In this paper the authors give definitions of temporal data and temporal databases. The authors present approaches to time modeling on the basis of which the types of time stamps used in temporal databases are described. The paper identifies two main ways to implement temporal systems using current relational database: implementation of temporal support at the application level and expansion of the non-temporal relational model to the temporal one. As a result, for each approach the authors identified respective advantages and disadvantages.
77-30569/225699 Temporal relational data model adaptation in the multidimensional space
Engineering Education # 09, September 2011
The article is devoted development of the technique of temporal relational data model adaptation in the multidimensional space. Limitations of temporal relational data models with modified data structure have been described if existing methods of their implementation are used. The multidimensional space structure for temporal relational model is offered and the multidimensional matrix algebra for operating with such space is specified to reduce these disadvantages. Transformation from the relational data model to the multidimensional space and inverse transformation have been developed based on particular structure of the multidimensional space and the algebra of multidimensional matrixes. As a result the technique of temporal relational data model adaptation has been specified which includes the single transformation from an initial relational data model to multidimensional space, change and performance of queries to such multidimensional temporal relational model with modified data structure.
Multidimensional matrix algebra for adapted data model processing
Engineering Education # 07, July 2011
The article is devoted development of the mathematical tool for processing of the adapted data model. The generalized structure of the multidimensional space which describes the relational model is offered for the adapted data model. The offered structure of multidimensional space is considered as a multidimensional matrix. The multidimensional matrix set based on the multidimensional matrix of the whole multidimensional space defines various parts of this space. Different operations for the multidimensional matrix set are entered and the multidimensional matrix algebra is defined.
Adapted model of the data on the basis of multidimensional space
Engineering Education # 10, October 2010
The article is devoted development of the adapted data model. Disadvantages of the table data representation used in relation databases have been investigated and the data model based on the multidimensional space has been offered. The structure of the multidimensional space has been offered for the adapted data model and the workflow scheme with such multidimensional space has been resulted.
Model of representation of knowledge at creation of adaptive information system
Engineering Education # 03, March 2010
The article is devoted development of adaptive information system based on the knowledge base. The class of adaptive information systems has been defined and the structure of such system has been described in this work. The decision example of one problem from domain connected with human resources management has been considered for illustration of the offered logic model of the knowledge base.
