IndexedDB
The Indexed Database API (commonly referred to as IndexedDB) is a JavaScript application programming interface (API) provided by web browsers for managing a NoSQL database of objects. It is a standard maintained by the World Wide Web Consortium (W3C). As an alternative to the Web storage standard, IndexedDB can provide more storage capacity. Web storage has fixed limits per website, but IndexedDB limits are "usually quite large, if they exist at all". Use cases for IndexedDB include caching web application data for offline availability. Some browser modules, such as devtools or extensions, may also use it for storage. History Support for IndexedDB was added to Firefox version 4, Google Chrome version 11, Internet Explorer version 10, Safari version 8, and Microsoft Edge version 12. Web SQL Database was a prior API developed by Apple. But Firefox refused to add support for it and argued against it becoming a standard because it would codify the quirks of SQLite. It was thus de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web SQL Database
Web SQL Database was a web browser API specification for storing data in databases that can be queried using SQL variant. Introduced in 2011 and quickly deprecated in favor of Web Storage API and IndexedDB, WebSQL was removed from browsers by April 2024. The technology was only ever implemented in Blink-based browsers like Google Chrome and the new Microsoft Edge, and WebKit-based browsers like Safari. Support The API is supported by Google Chrome, Opera, Microsoft Edge, and the Android Browser, albeit support is slowly being phased out. Web SQL was deprecated and removed for third-party contexts in Chromium 97. Web SQL access in insecure contexts is deprecated as of Chrome/Chromium 105 at which time a warning message was shown in the Chrome DevTools Issue panel. The API will be entirely removed from Chrome 124. Timeline In January 2010, Google announced availability of WebSQL Database API in Google Chrome. Mozilla Corporation developers publicly opposed the technology and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SQLite
SQLite ( "S-Q-L-ite", "sequel-ite") is a free and open-source relational database engine written in the C programming language. It is not a standalone app; rather, it is a library that software developers embed in their apps. As such, it belongs to the family of embedded databases. It is the most widely deployed database engine, as it is used by several of the top web browsers, operating systems, mobile phones, and other embedded systems. Many programming languages have bindings to the SQLite library. It generally follows PostgreSQL syntax, but does not enforce type checking by default. This means that one can, for example, insert a string into a column defined as an integer. Although it is a lightweight embedded database, SQLite implements most of the SQL standard and the relational model, including transactions and ACID guarantees. However, it omits many features implemented by other databases, such as materialized views and complete support for triggers and AL ...

The browser is also the main component of ChromeOS, where it serves as the platform for web applications. Most of Chrome's source code comes from Google's free and open-source software project Chromium (web browser), Chromium, but Chrome is licensed as proprietary freeware. WebKit was the original Browser engine, rendering engine, but Google eventually Fork (software development), forked it to create the Blink (browser engine), Blink engine; all Chrome variants except iOS used Blink as of 2017. , StatCounter estimates that Chrome has a 65% worldwide usage share of web browsers, browser market share (after peaking at 72.38% in November 2018) on personal comput ...

JavaScript
JavaScript (), often abbreviated as JS, is a programming language and core technology of the World Wide Web, alongside HTML and CSS. Ninety-nine percent of websites use JavaScript on the client side for webpage behavior. Web browsers have a dedicated JavaScript engine that executes the client code. These engines are also utilized in some servers and a variety of apps. The most popular runtime system for non-browser usage is Node.js. JavaScript is a high-level, often just-in-time–compiled language that conforms to the ECMAScript standard. It has dynamic typing, prototype-based object-orientation, and first-class functions. It is multi-paradigm, supporting event-driven, functional, and imperative programming styles. It has application programming interfaces (APIs) for working with text, dates, regular expressions, standard data structures, and the Document Object Model (DOM). The ECMAScript standard does not include any input/output (I/O), such as netwo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Wide Web Consortium
The World Wide Web Consortium (W3C) is the main international standards organization for the World Wide Web.

Web Application
A web application (or web app) is application software that is created with web technologies and runs via a web browser. Web applications emerged during the late 1990s and allowed for the server to dynamically build a response to the request, in contrast to static web pages. Web applications are commonly distributed via a web server. There are several different tier systems that web applications use to communicate between the web browsers, the client interface, and server data. Each system has its own uses as they function in different ways. However, there are many security risks that developers must be aware of during development; proper measures to protect user data are vital. Web applications are often constructed with the use of a web application framework. Single-page applications (SPAs) and progressive web apps (PWAs) are two architectural approaches to creating web applications that provide a user experience similar to native apps, including features such as smoo ...

Deprecation
Deprecation is the discouragement of use of something human-made, such as a term, feature, design, or practice. Typically something is deprecated because it is claimed to be inferior compared to other options available. Something may be deprecated when it cannot be controlled, such as a term. Even when it can be controlled, something may be deprecated even when it might be useful for example, to ensure compatibility and it may be removed or discontinued at some time after being deprecated. Etymology In general English usage, the verb "to deprecate" means "to express disapproval of (something)". It derives from the Latin deponent verb ''deprecari'', meaning "to ward off (a disaster) by prayer". An early documented usage of "deprecate" in this sense is in Usenet posts in 1984, referring to obsolete features in 4.2BSD and the C programming language. An expanded definition of "deprecate" was cited in the Jargon File in its 1991 revision, and similar definitions are found in ...
