Apache Solr
Solr (pronounced "solar") is an open-source enterprise-search platform, written in Java. Its major features include full-text search, hit highlighting, faceted search, real-time indexing, dynamic clustering, database integration, NoSQL features and rich document (e.g., Word, PDF) handling. Providing distributed search and index replication, Solr is designed for scalability and fault tolerance. Solr is widely used for enterprise search and analytics use cases and has an active development community and regular releases. Solr runs as a standalone full-text search server. It uses the Lucene Java search library at its core for full-text indexing and search, and has REST-like HTTP/XML and JSON APIs that make it usable from most popular programming languages. Solr's external configuration allows it to be tailored to many types of applications without Java coding, and it has a plugin architecture to support more advanced customization. Apache Solr is developed in an open, collaborat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Apache ( ) are several Southern Athabaskan language-speaking peoples of the Southwest, the Southern Plains and Northern Mexico. They are linguistically related to the Navajo. They migrated from the Athabascan homelands in the north into the Southwest between 1000 and 1500 CE. Apache bands include the Chiricahua, Jicarilla, Lipan, Mescalero, Mimbreño, Salinero, Plains, and Western Apache ( Aravaipa, Pinaleño, Coyotero, and Tonto). Today, Apache tribes and reservations are headquartered in Arizona, New Mexico, Texas, and Oklahoma, while in Mexico the Apache are settled in Sonora, Chihuahua, Coahuila and areas of Tamaulipas. Each tribe is politically autonomous. Historically, the Apache homelands have consisted of high mountains, sheltered and watered valleys, deep canyons, deserts, and the southern Great Plains, including areas in what is now Eastern Arizona, Northern Mexico (Sonora and Chihuahua) and New Mexico, West Texas, and Southern Colorado. These areas are c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

JSON
JSON (JavaScript Object Notation, pronounced or ) is an open standard file format and electronic data interchange, data interchange format that uses Human-readable medium and data, human-readable text to store and transmit data objects consisting of name–value pairs and array data type, arrays (or other serialization, serializable values). It is a commonly used data format with diverse uses in electronic data interchange, including that of web applications with server (computing), servers. JSON is a Language-independent specification, language-independent data format. It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data. JSON filenames use the extension .json. Douglas Crockford originally specified the JSON format in the early 2000s. Transcript: He and Chip Morningstar sent the first JSON message in April 2001. Naming and pronunciation The 2017 international standard (ECMA-404 and ISO/IEC 21778:2017) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hadoop
Apache Hadoop () is a collection of Open-source software, open-source software utilities for reliable, scalable, distributed computing. It provides a software framework for Clustered file system, distributed storage and processing of big data using the MapReduce programming model. Hadoop was originally designed for computer clusters built from commodity hardware, which is still the common use. It has since also found use on clusters of higher-end hardware. All the modules in Hadoop are designed with a fundamental assumption that hardware failures are common occurrences and should be automatically handled by the framework. Overview The core of Apache Hadoop consists of a storage part, known as Hadoop Distributed File System (HDFS), and a processing part which is a MapReduce programming model. Hadoop splits files into large blocks and distributes them across nodes in a cluster. It then transfers JAR (file format), packaged code into nodes to process the data in parallel. This appro ...

Enterprise Content Management
Enterprise content management (ECM) extends the concept of content management by adding a timeline for each content item and, possibly, enforcing processes for its creation, approval, and distribution. Systems using ECM generally provide a secure repository for managed items, analog or digital. They also include one (or more) methods for importing content to manage new items, and several presentation methods to make items available for use. Although ECM content may be protected by digital rights management (DRM), it is not required. ECM is distinguished from general content management by its cognizance of the processes and procedures of the enterprise for which it is created. Definitions * Late 2005: The technology was used to capture, manage, store, preserve, and deliver content and documents related to organizational processes * Early 2006: ECM tools and strategies allowed the management of an organization's unstructured information, wherever that information exists. * Early 2 ...

Content Management System
A content management system (CMS) is computer software used to manage the creation and modification of digital content ( content management).''Managing Enterprise Content: A Unified Content Strategy''. Ann Rockley, Pamela Kostur, Steve Manning. New Riders, 2003. It is typically used for enterprise content management (ECM) and web content management (WCM). ECM typically supports multiple users in a collaborative environment, by integrating document management, digital asset management, and record retention. Alternatively, WCM is the collaborative authoring for websites and may include text and embed graphics, photos, video, audio, maps, and program code that display content and interact with the user. ECM typically includes a WCM function. Structure A CMS typically has two major components: a content management application (CMA), as the front-end user interface that allows a user, even with limited expertise, to add, modify, and remove content from a website without the interve ...

Kubernetes
Kubernetes (), also known as K8s is an open-source software, open-source OS-level virtualization, container orchestration (computing), orchestration system for automating software deployment, scaling, and management. Originally designed by Google, the project is now maintained by a worldwide community of contributors, and the trademark is held by the Cloud Native Computing Foundation. The name ''Kubernetes'' originates from the Greek language, Greek κυβερνήτης (kubernḗtēs), meaning 'governor', 'helmsman' or 'pilot'. ''Kubernetes'' is often abbreviated as ''K8s'', counting the eight letters between the ''K'' and the ''s'' (a numeronym). Kubernetes assembles one or more computers, either virtual machines or bare machine, bare metal, into a Computer cluster, cluster which can run workloads in containers. It works with various container runtimes, such as containerd and Cloud Native Computing Foundation#CRI-O, CRI-O. Its suitability for running and managing workloads of ...

WAR (file Format)
In software engineering, a WAR file (Web Application Resource or Web application ARchive) is a file used to distribute a collection of JAR (file format), JAR-files, Jakarta Server Pages, Jakarta Servlets, Java (programming language), Java class (file format), classes, XML files, tag libraries, static web pages (HTML and related files) and other resources that together constitute a web application. Content and structure A WAR file may be digital signature, digitally signed in the same way as a JAR (file format), JAR file in order to allow others to determine where the source code came from. There are special files and directories within a WAR file: * The /WEB-INF directory in the WAR file contains a file named web.xml which defines the structure of the web application. If the web application is only serving JSP files, the web.xml file is not strictly necessary. If the web application uses servlets, then the servlet container uses web.xml to ascertain to which Jakarta Servlet, serv ...

Carrot2
Carrot² is an open source search results clustering engine. It can automatically cluster small collections of documents, e.g. search results or document abstracts, into thematic categories. Carrot² is written in Java and distributed under the BSD license. History The initial version of Carrot² was implemented in 2001 by Dawid Weiss as part of his MSc thesis to validate the applicability of the STC clustering algorithm to clustering search results in Polish. In 2003, a number of other search results clustering algorithms were added, including Lingo, a novel text clustering algorithm designed specifically for clustering of search results. While the source code of Carrot² was available since 2002, it was only in 2006 when version 1.0 was officially released. In the same year, version 2.0 was released with improved user interface and extended tool set. In 2009, version 3.0 brought significant improvements in clustering quality, simplified API and new GUI application for tuning ...

HTML
Hypertext Markup Language (HTML) is the standard markup language for documents designed to be displayed in a web browser. It defines the content and structure of web content. It is often assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript, a programming language. Web browsers receive HTML documents from a web server or from local storage and browser engine, render the documents into multimedia web pages. HTML describes the structure of a web page Semantic Web, semantically and originally included cues for its appearance. HTML elements are the building blocks of HTML pages. With HTML constructs, HTML element#Images and objects, images and other objects such as Fieldset, interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, Hyperlink, links, quotes, and other items.
