Relatively new for the Windows operating system is the PowerShell command shell, that was designed to replace the elder task automation tools, which are the *** command shell and the Windows Script Host. At the appearance of PowerShell many problems were solved, in particular, the problem of integrating the command line with objects that are supported in the operating system, and working with random data sources. The main feature of the PowerShell com-mand shell is that all results of its commands are represented as sets of objects of certain .NET classes, because this command shell is built on the .NET platform. At the same time, the capabilities of PowerShell are not thoroughly studied. The article presents a study of this command shell in the context of an object database and simple On-Line Analytical Processing (OLAP) system building based on the described classes directly in PowerShell scripts. Main results of building an OLAP system by means of standard PowerShell commands, .NET classes, and creating classes for storing multidimensional data are also presented.

The categorical relationships play a crucial role for choosing of computer database. Based on it, association rules display the link among the 2 categories. Because the object oriented elegance for the computer code cultivates, the relationships among the categories. Additionally rise near the complicated computer code style. However, one will develop improved object-oriented style through right association rules among groups or categories. The present paper deals to style the proper association rules for the object-oriented databases taken from the categories. A true scenario of Electricity Bill Deposit System (EBDS) and user interested items by analyzing user behavior history in social network environment. Both applications are taken into account in Indian situation and Apriori Algorithmic rule is employed for locating the employment of recurrent information sets through the proper association rules. The association rules area unit deliberate through famous Unified Modeling Language. The current paper work is to the associate degree carrying out of Apriori algorithmic rule towards the information of EBDS.

We create the computing and information system to study prospective interstate power grids. As a part of the system, an object-oriented database for storing and processing energy and power data is constructed. The software tool for data extracting, with their subsequent processing and output of the computing results in the form of tables, graphs and charts on geographical maps have been developed. For research of the interstate power grids expansion, the optimization math Model as a main computing part of the developed software is used. © 2019 IEEE.

The paper presents Data processing and optimization system for studying and making rational decisions on the formation of interstate electric power interconnections, with aim to increasing effectiveness of their functioning and expansion. The technologies for building and integrating a Data processing and optimization system including an object-oriented database and a predictive mathematical model for optimizing the expansion of electric power systems ORIRES, are described. The technology of collection and pre-processing of non-structured data collected from various sources and its loading to the object-oriented database, as well as processing and presentation of information in the GIS system are described. One of the approaches of graphical visualization of the results of optimization model is considered on the example of calculating the option for expansion of the South Korean electric power grid.

A New Approach for Query Processing and Optimization in Fuzzy object-oriented Database 1

For enhancing the efficiency of processing users' queries, all database management systems (DBMSs) must conduct query preprocessing, or query optimizing. This paper proposes a new model for the Fuzzy object-oriented DBMS (FOO-DBMS), which optimizes the query statements and processes the data before returning back to users based on fuzzy object algebra and equivalent transformation rules. Discussions on this model are also presented with computation and analysis.

45th International Conference on Very Large Data Bases, VLDB 2019

Database applications are often developed with object-oriented languages while using relational databases as the backend. To accelerate these applications, developers would manually design customized data structures to store data in memory, and ways to utilize such data structures to answer queries. Doing so is brittle and requires a lot of effort. Alternatively, developers might automate the process by using relational physical design tools to create materialized views and indexes instead. However, the characteristics of object-oriented database applications are often distinct enough from traditional database applications such that classical relational query optimization techniques often cannot speed up queries that arise from such applications, as our experiments show. To address this, we build CHESTNUT, a data layout generator for in-memory object-oriented database applications. Given a memory budget, CHESTNUT generates customized in-memory data layouts and query plans to answer queries written using a subset of the Rails API, a common framework for building object-oriented database applications. CHESTNUT differs from traditional query optimizers and physical designers in two ways. First, CHESTNUT automatically generates data layouts that are customized for the application after analyzing their queries, hence CHESTNUT-generated data layouts are designed to be efficient to answer queries from such applications. Second, CHESTNUT uses a novel enumeration and verification-based algorithm to generate query plans that use such data layouts, rather than rule-based approaches as in traditional query optimizers. We evaluated CHESTNUT on four opensource Rails database applications. The result shows that it can reduce average query processing time by over 3.6x (and up to 42x), as compared to other in-memory relational database engines. © 2019, is held by the owner/author(s).

Data modeling across the evolution of database technology

Studies in Big Data

Studies in Big Data 2018年 31卷 221-234页

作者： Atzeni, Paolo Cabibbo, Luca Torlone, Riccardo Dipartimento di Ingegneria Università Roma Tre Rome Italy

Data modeling has always been a fundamental issue across the whole evolution of database technology, as it is witnessed by the vast literature addressing this issue across the last thirty years. In this paper, we present the studies done by members of the database and big data research group of Roma Tre University on the issue of data modeling in the context of several milestones in field of databases: logic-based and object-oriented databases, data warehousing, and NoSQL systems. We also discuss our proposal for a general framework that allows the description of different models and the translation of schemas from one to another. © Springer International Publishing AG 2018.

The number of 3D models available on the web is growing exponentially, given the enormous digitized objects with 3D scanners and synthetic objects produced by modeling software. Traditional text-based search techniques are not always effective for 3D data and aren't very helpful to users. 3D models indexing and searching is a process of coding and describing the shape of 3D models. It aims to facilitate the query on large 3D object databases. To accomplish this task, two approaches can be discussed: the 3D/3D approach that acts directly on the shape of the 3D model, and the 2D/3D one that is based on the projection of the 3D object onto a given plane. In this work, we discuss for each approach the available the main characteristics. © 2017 Copyright is held by the owner/author(s).

The main objective of the work presented is to help architects to develop solutions based on unconventional approaches and to do so, a conceptual framework is presented. The whole framework starts from the requirements and the use cases capture and the Architectural object database construction. Then it continues with an architectural automated synthesis. The framework uses concepts taken from the System Engineering field and the graph theory and can be applied to several system to design of different domains. The helicopter dynamic systems are multi-domain and totally encounter the scope of the framework. © 2017 by the American Helicopter Society International, Inc.
