XQuery XQuery is a query and functional programming language that is designed to query and transform collections of structured and unstructured data, usually in the form of XML, text and with vendor-specific extensions for other data formats (JSON, binary, etc.). The language is developed by the XML Query working group of the W3C. The work is closely coordinated with the development of XSLT by the XSL Working Group; the two groups share responsibility for XPath, which is a subset of XQuery. XQuery 1.0 became a W3C Recommendation on January 23, 2007. XQuery 3.0 became a W3C Recommendation on April 8, 2014. "The mission of the XML Query project is to provide flexible query facilities to extract data from real and virtual documents on the World Wide Web, therefore finally providing the needed interaction between the Web world and the database world. Features XQuery contains a superset of XPath expression syntax to address specific parts of an XML document. Examples "Hello World"
JSON World Wide Web Consortium The World Wide Web Consortium (W3C) is the main international standards organization for the World Wide Web (abbreviated WWW or W3). Founded and currently led by Tim Berners-Lee, the consortium is made up of member organizations which maintain full-time staff for the purpose of working together in the development of standards for the World Wide Web. As of 7 September 2013[update], the World Wide Web Consortium (W3C) has 383 members. W3C also engages in education and outreach, develops software and serves as an open forum for discussion about the Web. History The World Wide Web Consortium (W3C) was founded by Tim Berners-Lee after he left the European Organization for Nuclear Research (CERN) in October, 1994. W3C tries to enforce compatibility and agreement among industry members in the adoption of new standards defined by the W3C. It was originally intended that CERN host the European branch of W3C; however, CERN wished to focus on particle physics, not information technology.
get/ohaskell.pdf Web Services Interoperability It is governed by a Board of Directors consisting of the founding members (IBM, Microsoft, BEA Systems, SAP, Oracle, Fujitsu, Hewlett-Packard, and Intel) and two elected members (currently, Sun Microsystems and webMethods). Since joining OASIS, other organizations have joined the WS-I technical committee including CA Technologies, JumpSoft and Booz Allen Hamilton. The organization's deliverables include profiles, sample applications that demonstrate the profiles' use, and test tools to help determine profile conformance. WS-I Profiles According to WS-I, a profile is A set of named web services specifications at specific revision levels, together with a set of implementation and interoperability guidelines recommending how the specifications may be used to develop interoperable web services. WS-I Profile Compliance The WS-I is not a certifying authority; thus, every vendor can claim to be compliant to a profile. "We expect enforcement of that brand to be market-driven.
MySQL 5.7 Reference Manual :: 2 Installing and Upgrading MySQL Determine whether MySQL runs and is supported on your platform. Please note that not all platforms are equally suitable for running MySQL, and that not all platforms on which MySQL is known to run are officially supported by Oracle Corporation. For information about those platforms that are officially supported, see on the MySQL Web site. Choose which distribution to install. Several versions of MySQL are available, and most are available in several distribution formats.
XQuery and XPath Data Model The XQuery and XPath Data Model (XDM) is the data model shared by the XPath 2.0, XSLT 2.0 and XQuery programming languages. It is a W3C recommendation and forms an integral part of all three languages. Originally, it was based on the XPath 1.0 data model which in turn is based on the XML Information Set. Разборка и чистка ноутбука Acer Aspire E1-531 Мы разберем в этот раз Acer Aspire E1-531, прочистим его, и усилим охлаждение. Разборка и чистка ноутбука Acer Aspire E1-531 как всегда начнется с визуального ознакомления: Это у нас нижняя сторона,извлечем батарею сдвинув в стороны зажимы крепления ее. Как видим модель Q5WPH, но при покупке нам продали Acer Aspire E1-531. Снимаем нижнюю крышку (2 болта выкрутим и тянем на себя) и видим под ней оперативу (верхнее фото) и жесткий (нижнее фото): Оттягиваем жесткий влево и снимаем, и оперативу извлекаем, так же все болты что видим выкручиваем: Теперь переворачиваем и смотрим что первым разбирать — верхнюю панельку или клавиатуру: Снимаем клавиатуру, аккуратно отжимаем зажимы и постепенно освобождая от каждого зажима: Незабываем про шлейфик а аккуратно его снимаем: Что вышло: Освобождаем все порты и разьемы от наших пабрекушек (usb,SD,aux): Освобоождаем все шлейфы и зажимы: Теперь выкручиваем wi-fi и вытягиваем его провода со стороны клавиатуры: Вот наша крышечка сверху:
Web service A Web service is a method of communications between two electronic devices over a network. It is a software function provided at a network address over the web with the service always on as in the concept of utility computing. The W3C defines a Web service as: a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format (specifically WSDL). The W3C also states: We can identify two major classes of Web services:REST-compliant Web services, in which the primary purpose of the service is to manipulate XML representations of Web resources using a uniform set of stateless operations; andArbitrary Web services, in which the service may expose an arbitrary set of operations. Explanation Many organizations use multiple software systems for management. Rules for communication between different systems need to be defined, such as: Web API Automated design methods Criticisms
MySQL Commands This is a list of handy MySQL commands that I use time and time again. At the bottom are statements, clauses, and functions you can use in MySQL. Below that are PHP and Perl API functions you can use to interface with MySQL. Below when you see # it means from the unix shell. To login (from unix shell) use -h only if needed. # [mysql dir]/bin/mysql -h hostname -u root -p Create a database on the sql server. mysql> create database [databasename]; List all databases on the sql server. mysql> show databases; Switch to a database. mysql> use [db name]; To see all the tables in the db. mysql> show tables; To see database's field formats. mysql> describe [table name]; To delete a db. mysql> drop database [database name]; To delete a table. mysql> drop table [table name]; Show all data in a table. mysql> SELECT * FROM [table name]; Returns the columns and column information pertaining to the designated table. mysql> show columns from [table name]; Show certain selected rows with the value "whatever". Sum column. or
Service-oriented architecture See also the client-server model, a progenitor concept A Service-Oriented Architecture (SOA) is a design pattern in which software/application components provide services to other software/application components via a protocol, typically over a network and in a loosely-coupled way. The principles of service-orientation are independent of any vendor, product or technology. A service is a self-contained unit of functionality, such as retrieving an online bank statement. By that definition, a service is a discretely invokable operation. However, in the Web Services Definition Language (WSDL), a service is an interface definition that may list several discrete services/operations. And elsewhere, the term service is used for a component that is encapsulated behind an interface. Services can be combined to provide the complete functionality of a large software application. A SOA makes it easier for software components on computers connected over a network to cooperate. Overview
