Future of web DB

A web database is a system for storing and displaying information that is accessible from the Internet / web.

A web database is a system for storing information that can then be accessed via a website.

A web database is a database that can be queried and/or updated through the World Wide Web (WWW). As web technologies are evolving, the WWW turned out to be the preferred medium for many applications, e.g., e-commerce and digital libraries. These applications use information that is stored in huge databases and can only be retrieved by issuing direct queries to the back-end databases. Database-driven web sites have their own interfaces and access forms that create HTML pages on-the-fly. Web database technologies define the way that these forms can connect to and retrieve data from database servers.

Large businesses rely on databases to store customer information. Because this information is accessible wherever Internet access is available, customers don't have to go to a local banking branch, for example, to access their account information.

Client interacting with web server.

Step 1: The GET request.

Client interacting with web server.

Step 2: The HTTP response.

Checking that the request is authorized

The server first responds by sending a line of text that indicates the

HTTP version, followed by a numeric code and a phrase

describing the status of the transaction. For example,

HTTP/1.1 200 OK

(Indicates success)

Whereas HTTP/1.1 404 Not found

informs the client that the web server could not locate the

requested resource.
