Articles in Data Storage Structures
As a result of the development of the chapters materials, students should know - classification of models and methods of storage and retrieval of data; basic design and operation of banks and databases; their assignment and functions; - the basis for building and operating information systems; and knowledge bases; work with information systems in database management; work with information in global computer networks and corporate data collection Data storage models and techniques exist both in the economy and in other areas, objects that need to be stored and all relate to each…
Storage structures in the tabular database and databases indices are usually stored on a hard drive in one of many forms, numbered / non-numbered non-numbered Flat Files, ISAM, Pupils, Hash baskets or B+ trees. They have different advantages and disadvantages discussed in this section. B+ trees and ISAM are the most commonly used. Arbitrary storage - usually stores records in the order in which they were placed. While the efficiency of the bidding is good, it may appear that the extraction time would be ineffective, but this is usually never very important, as most databases…
CIO, IT directors, business development directors, project managers, IT managers and specialists, communications, weak enterprise systems responsible for establishing and operating the organizations IT resources. Companies facing the task of modernizing and/or establishing data storage and processing systems. Space is virtual, information is real. Monitor Virtualization was not new and was introduced by IBM in the 1960s. Virtualization is a proven software technology that quickly transforms the IT infrastructure and radically changes the way users and computers interact. The…
The first five columns of the table use traditional SQL data types and track the information on the product sold, including its identification number, the manufacturer, the name of the goods, the storage unit (stock-keeping unit, SKU) and the proposed retail price (suggested retail price, SRP). The commentstable contains XML data containing information on goods received from buyers. Please note that the internal structure of XML-data is not specified when the XML table is established. It s defined by design itself. XML documents describe themselves and their internal structure…
We re developing dual-track tools. In the platform, we added a set of battle functions to work with numbers. With their help, you will be able to deal with the spreading tasks easier and easier. Tell your friends: We have developed a new mechanism to restructure the database, which allows the configuration to be upgraded at an average of 3-4 times and, in some cases, in order. Tell your friends: Now, with enhanced configuration, you can add to the application decision your own data storage structures: directories, documents, data registers. Tell your friends: We have implemented…
This article is an anon to new functionality. It is not recommended that the contents of this article be used to develop new functionality. A full description of the new functionality will be provided in the documentation to the relevant version. A complete list of changes in the new version is provided in the v8Update.htm file. Planned in version 8.3.11. Now, with enhanced configuration, you can add to the application decision your own data storage structures: directories, documents, data registers. In expansion, you add (or modify) an appropriate configuration facility. When…
PDF version (310 Kb) The article describes the basic architectures of data warehouses and addresses some general principles for their construction. Details are provided on how to present hierarchies in the data relay structure. The introduction in the early eighties of the past century, while registering information systems are rapidly developing, has created an understanding of the limited availability of data for data analysis and the building of support and decision-making systems. Recording systems were established to automate routine business operations generating accounts…
Alexandre Sviridenkov of the Database is usually not self-reliant, is part of the information system. Irrespective of the number of links in the system, the interface with the user is located on the other side of the OBD end, and the programmers task is to provide a simple and understandable way of dealing with OBD data and facilities. With all its coherence and visibility, the classic way of storing and presenting the facilities of the developed entity has some of the disadvantages encountered by any developer who has attempted to implement such a system with sufficient complexity…
Platform 1C is a high-level tool for handling databases. In general, the developer does not need to wonder what and what happens on the side of the OBD system, because the platform itself decides how many tables and what fields within it will be. However, in major projects, there is a need to work directly with data, for example, to analyse information from outside means or, as in my case, to integrate the database with external applications. In such a situation, there is a need to know in which fields of physical tables we need information. This is the case where the built-in…
For starters, we will learn to program for this the function of obtaining the control of Bazan. It returns information on the structure of the database tables of all configurations (as a table of values). If a storage structure is needed not for the entire base but only for certain facilities, either the configuration itself or their names (as a mass) can be transferred as a parameter. For example: Massive Metadata = New Massive; Massive Metadata. Added by Masters. Structured = Receive the Bazinian control system (Massiv-Metada); Structured OBD = Receive the Bazinian control…
