Database Performance Assessment Methodology

The database of the automated control system is an artificial functioning object that provides information services. The process of database functioning occurs with some finite efficiency. To improve the information support of the automated system, it is necessary to obtain an accurate assessment of the efficiency of the basis – the database. Modern approaches to assessing the quality of databases based on the standards ISO / IEC 25012: 2008 "Software engineering – Software product. Quality Requirements and Evaluation (SQuaRE) – Data quality model" and ISO / IEC 25024: 2015 "Systems and software engineering – Systems and software Quality Requirements and Evaluation (SQuaRE) – Measurement of data quality" do not provide the ability to obtain objective numerical estimates. There is a contradiction between the need to obtain accurate estimates of the intensity of significant properties of the database and the available tools for solving this problem. Purpose. Development of a template of a parametric database model suitable for forming a list of operational and technical requirements for a database in the process of assessing the effectiveness of its functioning for its intended purpose. Results. A list of significant operational, result and resource properties of a typical database of an automated control system for a complex organizational and technical object has been formulated, using the example of a spacecraft flight control center (MCC). Measurable parameters of database functioning as an artificial object implementing a targeted process of satisfying the information needs of users (applied processes) have been put forward. Proposals have been developed for the structures of convolution of measurable parameters of database functioning, presented in the form of oriented graphs. Interpretations have been developed for formulating private indicators of the effectiveness of the functioning of the automated control system database. A methodological basis has been created for developing procedures for assessing the effectiveness of the database. Practical significance. A set of structural models of private performance indicators of the functioning of the database of an automated control system for an organizational and technical object, provided with measurable parameters, has been developed to form procedures for assessing the effectiveness of its functioning in the task of improving the management cycle.
