Web SQL Database is a deprecated web browser API specification for storing data in databases that can be queried using SQL variant. The technology was only ever implemented in Blink-based browsers like Google Chrome and the new Microsoft Edge, and WebKit-based browsers like Safari. WebSQL is being phased out in favor of WebStorage and IndexedDB and OPFS, but still available in some contexts under restrictive conditions. 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. In January 2010, Google announced availability of WebSQL Database API in Google Chrome. Mozilla Corporation developers publicly opposed the technology and at the same were the main proponents behind an 'alternative storage' standard, IndexedDB. Mozilla argued that ratification of WebSQL as a standard would codify the quirks of SQLite implementation.

In November 2010, the W3C Web Applications Working Group ceased working on the specification, citing a lack of independent implementations (i.e. using database system other than SQLite as the backend) as the reason the specification could not move forward to become a W3C Recommendation. In September 2019, Apple released Safari 13 which removed WebSQL entirely. In November 2021, Chrome 97 removed WebSQL support in third-party contexts. In February 2023, Chrome 110 removed WebSQL support in insecure contexts but allowed exceptions set with an enterprise policy. In October 2023, Chrome 119 was shipped with WebSQL disabled in all contexts by default, with an ability to re-enable it until Chrome 123 via a deprecation trial in some contexts. In April 2024, Chromium-based browsers, including Chrome 124 and Edge 124 have removed support WebSQL completely. Nelson, Anne Fulcher, and Nelson, William Harris Morehead. 2001).

Web SQL support is completely removed. In prior releases, Web SQL support was disabled by default but could be re-enabled via the WebSQLAccess policy. After this change, there is no longer any mechanism to enable Web SQL support. This change is happening in the Chromium project, on which Microsoft Edge is based.

The Internet has revolutionized the way we communicate. E-mail has been the most rapidly adopted form of communication ever known. Less than two decades ago, not many people had heard of it. Now, many of us e-mail instead of writing letters or even calling people on the phone. People around the world send out billions of e-mail messages every day. But sometimes even e-mail isn't fast enough. You might not know if a person you want to e-mail is online at that moment. Also, if you're e-mailing back and forth with someone, you usually have to click through a few steps. This is why instant messaging (IM) has become so popular. You can IM with anyone on your buddy list or contact list as long as that person is online. You type messages to each other into a small window that shows up on both of your screens. In this article, you will learn about the history of instant messaging and how it works.

You will also learn what the major IM programs are, what makes them different from each other and what the future holds for IM. The major online services, such as America Online (AOL), Prodigy and CompuServe, were the main way that ordinary people could connect and communicate with each other online. Online services provide the actual interface that you use when you're connected to the service, which creates a targeted experience for users. ­In the early 1990s, people began to spend more and more time on the Internet. Creative software developers designed chat-room software and set up chat rooms on Web servers. In a chat room, a group of people can type in messages that are seen by everyone in the "room." Instant messages are basically a chat room for just two people. That's when Mirabilis introduced ICQ, a free instant-messaging utility that anyone could use. ICQ, shorthand for "I seek you," uses a software application, called a client, that resides on your computer.
